  1. Florida Anthropology Society Annual Meeting

    Posted 1 year ago
    Hi all,

    I have been getting ready for the FAS meeting. It is being held towards the beginning of May in Avon Park, which is somewhere near Sebring.

    Anyways, I am presenting a ridiculously long-title paper called: A preliminary study of the midden burials from the Spanish River Complex, and their potential application to questions concerning status in pre-contact southeast Florida. Oh, and I mean the paper’s title is ridiculously long, the paper itself should fit in the required 15 minutes, and it has turned out to be kind of interesting. Comparing the closely associated midden burials to the mound burials, it is clear that life expectancy is always greater in the mound population, and with the exception of the first cohort the survivorship is also greater in the mound. Looks like decent biological evidence of differential status expressed in different burial locations to me!

  2. Update and Cradle of Christianity Exhibit Brief

    Posted 1 year ago
    Hello all,

    Let me see, what has been going on? After two weeks of straight work I decided to take a few days off due to family commitments (birthdays, Easter, etc). We had this month's GCAS meeting, which went well. We have a big exhibit opening soon, but I cannot mention anything about it just yet. TRUST ME, it is (or at least it was) BIG. My family also took a trip down to Fort Lauderdale to see the Cradle of Christianity exhibit at the Museum of Art. If I have time I will post an in depth review, but it was a good exhibit. It ends in the middle of April, so if you want to see it you need to go quickly.
  3. Quick One Again

    Posted 1 year ago
    Hello all,

    Unfortunately, this is another quick update.

    The Gold Coast Anthropological Society (GCAS) had our tour of the Ft. Lauderdale Historical Society two Sundays ago. It was an extremely good day out, and I think we all learnt something new about the history of South Florida.

    We also did some activities in celebration of Florida Archaeology Month (FAM) at the Florida Atlantic University (FAU) library. I gave a lecture about The Prehistory of Southeast Florida in the morning and evening, along with a hands-on workshop in the afternoon. Everything went well, except that I forgot to bring calipers for measuring (plastic) human bones. Luckily, the FAU Anthropology Department allowed me to borrow a pair.

    I am trying to finish up the work on the Boca Weir site, ready to present at the Florida Anthropology Society (FAS) annual meeting in May. In addition, I am attempting to bring together funding to carbon date this midden material, along with some items from an adjacent mound. Once this is done, I should be able to publish this data.

    Speaking of publishing, I sent off the new version of my current article. This one addressed the issues raised by peer-review. I am still waiting to hear if there are further comments from the editors.

    I am still waiting to hear about my application to the Ph.D. Comparative Studies program at FAU. If that does not come through, I may try to turn my dissertation topic into a book.

    Once I have finished working on the paper presentation for the FAS conference, I may have more time to fully update.
  4. Life Tables

    Posted 1 year ago
    Hello all,

    I am still extremely busy, working on the paper I am presenting at the FAS conference. I took today off from doing the osteological work to confirm that I could still do the required math for the life tables. What are life tables? Basically, for this type of investigation they are an important tool for paleodemographic analysis that includes things like death rates, survivorship, and life expectancy (FYI, more general information can be found on the Life Tables entry in Wikipedia). So, was I able to remember how to do them? Yes, but only with quite a bit of arduous and tedious effort. Essentially, I had to use a combination of old college notes, various books and articles, along with reviewing a bunch of online sources. Still, at least now I am confident that once the last bits of data are collected, I can do the required math for proper analysis.
  5. Brief Updates

    Posted 1 year ago
    Hello all,

    Very quick updates.

    I have re-submitted the article following the peer-review comments. It merely needs to go through a second pass with the editor, fix any remaining problems, and then it should be ready to be published.

    I have sent in the abstract for the FAS conference. In-other-words, I need to have all the research done, get the write-up finished, and be ready to be presented by May.

    Both Florida Archaeology Month exhibits have been installed and look good. The folks over at the FAU Library added some greenery to the installation, which now looks even better. So, I took more photos.

  6. Quick Update and Florida Archaeology Exhibit at the FAU Library: Photo Gallery

    Posted 1 year ago
    Hello all,

    I have been extremely busy. In the last two weeks I have put the finishing touches on the exhibit at the Children's Museum, been involved with the opening event at the Kid's Museum (photos coming soon), built and installed the exhibit for the FAU library, continued working on the Spanish River Complex project ensuring that it is far enough along to send in an abstract for a paper presentation at the FAS conference on that same subject, and I have been working on the editor's and reviewer's notes on my article, which need to be resubmitted by March 19th if there is a hope of making the next issue. If I have time I will update with more specifics on each of these items. Until then, here is the photo gallery of the Florida Archaeology exhibit at FAU's Main Library.


    Click to Enlarge


    First, I had to finish construction of the mounts and signage. I did not stick the stands to the backs of these items beforehand, because I wanted to see how everything worked in the case.


    Next up, everything had to be put in the case, arranged, and finalized. The image on the right shows the final set-up.


    With this being a library, books were also important. So, next to the case the library staff put up a couple of bookshelves with volumes on Florida Archaeology. They also added a guest book, and I am looking forward to reading the comments.


    In these three shots you can see close-ups of each section of the case. Going from left to right is loosely moving from the oldest material to the more modern.


    Finally, a close-up of the pottery boards, and one more shot of the entire exhibit.
  7. FAU Library Exhibit--Signage

    Posted 1 year ago
    Hello all,

    I have some good news, but first some background

    One of the primary reasons behind my agreement to do two exhibits on the Prehistory of Florida for the upcoming Florida Archaeology Month (FAM) was the notion of getting ‘two for one’ on a few factors. While going through the boxes of archaeological artifacts, pulling two pottery sherds instead of one is obviously an easy task. Another reason was (I hoped) I could utilize similar signage for each exhibit. Thereby, significantly reducing the workload. Infact, the writing aspect was the hardest part, the actual going through the archaeological archives was fun.

    The good news, I have just finished editing the drafts for the signage of the FAU Library exhibit, and 90% of it was a straight ‘cut and paste’ from the text I wrote for the Children’s Museum installation. Now, I realize I am still up at 2am working, but without having to do significantly more writing for the signage, I can actually go to bed soon.

    Oh, and if you click on the FAM website (see the link two paragraphs above), and search for events in Palm Beach County. Well, those three things that come up are our events. Hope to see you there (unless you do not live in South Florida, because then I think you have a good excuse for not coming).
  8. Chimps and Spears

    Posted 1 year ago
    Hi all,

    I found this article quite intriguing. The implications for Hominin Evolution are obvious, but the problem is wooden tools would not survive in the record. However, the possibilities for theoretical reconstruction are limitless. Indeed, with modern chimps observed utilizing such a vast tool kit, maybe we need to redefine what truly makes humans, well human. Additionally, the dividing line between the Australopithecines and Homo is getting downright blurry. Maybe it is time to move Homo habilis over to the other side and start our genus with Homo erectus. Afterall, it is at that point that we jump from being four feet tall to six feet. Then again, the more controversial answer has already been proposed by some folks (I am thinking Jared Diamond here). Moving the Chimpanzees, and hence all the common ancestors we share, into our genus. This could get a little confusing, what with such animals as Homo troglodytes, Homo afarensis, and Homo robustus. Right now I would settle for the former, but I find the latter concept fascinating for what it says about us (modern humans) in relation to the rest of the planet.

    BBC NEWS: Chimpanzees 'hunt using spears'

    Chimpanzees in Senegal have been observed making and using wooden spears to hunt other primates, according to a study in the journal Current Biology.


    Read the original at BBC News or

    Researchers documented 22 cases of chimps fashioning tools to jab at smaller primates sheltering in cavities of hollow branches or tree trunks.

    The report's authors, Jill Pruetz and Paco Bertolani, said the finding could have implications for human evolution.

    Chimps had not been previously observed hunting other animals with tools.

    Pruetz and Bertolani made the discovery at their research site in Fongoli, Senegal, between March 2005 and July 2006.

    "There were hints that this behavior might occur, but it was one time at a different site," said Jill Pruetz, assistant professor of anthropology at Iowa State University, US.

    "While in Senegal for the spring semester, I saw about 13 different hunting bouts. So it really is habitual."

    Jabbing weapon

    Chimpanzees were observed jabbing the spears into hollow trunks or branches, over and over again. After the chimp removed the tool, it would commonly smell or lick it.

    In the vast majority of cases, the chimps used the tools in the manner of a spear, not as probes. The researchers say they were using enough force to injure an animal that may have been hiding inside.

    In one case, Pruetz and Bertolani witnessed a chimpanzee extract a bushbaby with a spear.

    In most cases, the Fongoli chimpanzees carried out four or more steps to manufacture spears for hunting.

    In all but one of the cases, chimps broke off a living branch to make their tool. They would then trim the side branches and leaves.

    In a number of cases, chimps also trimmed the ends of the branch and stripped it of bark. Some chimps also sharpened the tip of the tool with their teeth.

    Adult males have long been regarded as the hunters in chimp groups.

    But the authors of the paper in Current Biology said females and juveniles were seen exhibiting this behaviour more frequently than adult males.
  9. Children’s Museum Installation

    Posted 1 year ago
    Greetings all,

    I spent today at the Children’s Museum of Boca Raton installing the new exhibit: the Prehistory of South Florida. All went quite well, and I think the kids are going to like it. There are some ‘wow’ pieces that should visually interest people. However, there is also quite a bit of text. Infact, there is probably more text than 95% of kids are ever going to read. However, if only 1 in 20 learn something; fantastic…

    The opening event is this coming Sunday. The only thing that needs to be finished between now and then are four information/visual posters.

    Click to Enlarge

    First up, the bigger case, when it is empty and then when it is full. This one focuses more on paleontology, but many of these animals were hunted by the Paleo-Indians.


    Here are some close ups on that case. I know children are going to like some of these fossils. Also, I have an atlatl, to remind people of the earliest Floridian hunters.


    Second, we have the smaller case, which focuses more on archaeology.


    With this close up, you get an idea of each level. I tried to tell a specific story on each shelf: 1) Faunal Material, 2) Tools, and 3) European Contact.


    Along with the two cases, there are a few other things that come with this exhibit. On the left, the folks at the Kid’s Museum put together a selection of books for the kids to read. In the middle, a saber-toothed cat with its own hat. And, on the right, three boards to hand around to the kids for them to touch and compare.


    Finally, here is everything together. As I said above, the only thing missing are the four posters. Those will be put in on Sunday.
  10. Finishing Projects and Sebring Dig Photos

    Posted 1 year ago
    Greetings all,

    I have been slowly finishing all the various projects I have been working on. Obviously, the Darwin Day presentation is done, as that day happened a few weeks back. I have completed an article called Historical Archaeology and the Stranahan Stores. This will be printed in the Ft. Lauderdale Historical Society’s newsletter and will advertise the little exhibit we put in there last year. I have finished mounting all the artifacts and writing all the text for the signage at the Children’s Museum of Boca Raton. Most of the text from that exhibit will be ‘cut and paste’ into the signs for the exhibit at the FAU library. No point in reinventing the wheel. I also have many of the artifacts for that exhibit pulled out of the collection; they just need to be mounted.

    The main project remaining is the investigation of material from an archaeological site on the coast. Longtime readers should remember a few months back when I posted photos of a trip to the site. The plan is to finish the work, and present the findings at the upcoming FAS annual meeting. Once I get feedback at the conference, I hope to write another article for The Florida Anthropologist.

    Of course, once these various things are finished, there are always new projects and events to work on. Although, I hope to hear soon if I have been accepted into the Ph.D. program at FAU. If that is the case, I will have to adjust my schedule. Rather than concentrating on events, I will need to work on original research on the archaeological collection. My hope is to have a significant portion of the osteological material at least preliminarily studied for usage in my dissertation. If I do not get into this program, the same research will be undertaken, but at a slower pace. My hope is that our Anthropology Department at the museum will become a central resource for human osteological study in South Florida. Although, due to time, funds, and the like, it will take a number of years to get everything truly researched and established.

    Finally, here are the pictures from the dig over in Sebring.

    Click to Enlarge

    It took us about 3 hours to get up to Sebring. Because we still wanted to have a good day’s work in the field, we left at 6am in the morning.


    Next up, you can see us consulting the maps, parking the van, and finally disappearing into the brush. In the photo on the left, you can see my fellow archaeologist's Robert and Rudy. And, on the photo on the right, can you find the blue van?


    We were working in a variety of different environments on this site, and we had to track through them all. We had to deal with open plains, thick underbrush, and even a water feature.


    It is amazing how quickly your fellow archaeologists can disappear into the wilderness. Oh, and it being Florida, despite being winter, it was hot and sunny.


    Interestingly enough, a lot of our ‘work’ on this day was walking between the shovel tests. However, we did do some actual archaeology, as you can see. We dug 11 of these shovel tests, but we found nothing. Oh, and in the very last photo I decided I should be in at least one shot, so there I am.
  11. Darwin Day Photos

    Hello,

    As promised, here are the photos from the Darwin Day event.

    Click to Enlarge

    First up we have birthday cake, a certain blogger giving his presentation, and our museum’s set-up at the event.


    Here are some close shots of our tables. You can see the David E. Crawley Neanderthal Collection of skull replicas, along with some flyers for future events.


    In addition, we had several items for sale, including ‘junk bone’ fossil fragments of mammoths, triceratops, shark teeth, and edmontosaurus, along with T-shirts.



    Finally, here are some shots of the wildlife at Flamingo Gardens, including peacocks, night herons, and otters.

    I also want to note that some other folks took a few of these photos, and I appreciate them allowing me to use the shots on this journal.
  12. Archaeological Dig, GCAS Meeting

    Posted 1 year ago
    Hello everyone,

    I spent yesterday in the field doing some excavation. Three of us drove up to a site near Sebring. The locality was horse country and was relatively flat and open. The worst problem was some thick underbrush in some areas. In total, we put in 11 shovel tests. These tests went down about a meter, or down to the water table. Incase you are wondering, we found absolutely nothing. I do have some photos and video from this day, and they are in line to be edited and uploaded.

    However, I have had the chance to upload some photos from the last Gold Coast Anthropological Society Meeting. Basically, before the meeting I decided to take some shots of the new T-Shirts and of the skulls that were used for the February Discussion on Neanderthal Evolution. I also meant to take some photos when everyone arrived, but it slipped my mind.

  14. Darwin Day Wrap-Up and the Species Problem

    Posted 1 year ago
    Hi all,

    Darwin Day was yesterday, and it was hosted at Flamingo Gardens. We all agreed that we must return to the gardens, because (at least from what I saw) they are beautiful and populated by a wide range of animals. For example, I saw several (very active) otters, a pair of bobcats, and an entire flock of peacocks and peahens. There was also a tram tour through the gardens, but I only saw the tram station and nothing else. Although, I could extrapolate from everything else I saw that the tram tour would probably be quite good too.

    As for the actual event, it went very well. There was an excellent turnout; I’d estimate 150 people. We literally ran out of seats. The general schedule was video/lecture/video/lecture and so on; although, we did stop for birthday cake. Of the three speakers (myself included), we covered a number of interesting subjects, including Darwin’s life and impact, Hominin fossils and Natural Selection, along with a review of the entire tree of life. We took a number of photos and video. If time permits, I will start uploading them soon.

    Now, to go off on one of my tangents, I had a lengthy discussion about species/speciation with someone at the event. Indeed, I consider myself a moderate lumper (grouping animals into a smaller number of species, even if they have a few different morphological features), and my classification of the species representing Hominin evolution reflects this fact. But, as the discussion went, just what is a species? And moreover, how do you reflect evolutionary change and (eventual) speciation in your taxonomic classification? The problem originates from the fact that the Linnaean system was developed in a 2D world where an animal either was or was not a member of a particular species (length being the range of features seen in the species, and width being the chasm between these entities). That notion was one of definite, unchanged animal categories without any consideration of time. However, the evolutionary world is one of 3 dimensions, including that significant and central temporal factor (so, time is essentially depth). It is this disconnect that is problematic.

    The theory of universal common descent dictates connection between all life; every species is related at some point. For example, cats and dogs share some type of mammalian-based common ancestor. So at what position as you move backwards in time should they no longer be classified as cats and dogs, and they become the common ancestor (lets say Cogs). I have never been fully satisfied with the answers that the Evolutionary Species concept gives for that question. Nonetheless, and despite my reservation, I have always defined paleo-species by the possession of a certain suite of apomorphic features. However, accounting for the issues with the Biological Species concept (for example, the ever-increasing prevalence of clearly fertile hybrids being a concern), well even this seemingly simple definition of species is thorny; thus, what can be said about something through time? I do wonder if the very concept of paleo-species needs to be re-evaluated? How do you integrate discrete (although sometimes quite fuzzy) modern-day biologically-defined species, with the entire history of the planet? Now, it is not that I do not think clear taxonomic relationships can be demonstrated, it is just when you get down to the ‘nitty-gritty.’ Is there really such a thing as a species in the past? Indeed, do species really exist at all when you look in the time dimension?

    These various ramblings are not some new; the ‘species problem’ has been a fixture in biology for a number of years. Still, I sometime wonder if a novel system maybe developed to unify the Linnaean 2D world with the time component? Is that system going to be something akin to the ‘PhyloCode’? I simply do not know. Still, universal common descent is such a simple and majestic concept; it would be almost poetic to have a categorization system that matches this simplicity.
  15. Darwin Day, Apples, Children’s Museum

    Posted 1 year ago
    Greetings one and all,

    I decided to change around the Darwin Day presentation a little. I dropped Darwin's finches and some of the introduction stuff. I settle on being less technical. So, I have added a couple of new sections talking generally about Australopithecines and Homo erectus, which compliments my already planned sections on Homo heidelbergensis and the Neanderthals. I have also thrown together a couple of posters with photos of various fossils representing these groups. I will also employ a slightly different introduction, explaining what a scientific theory is, and using the theory of gravity as an example. That should hopefully combat the 'it is just a theory' retort. Afterall, our understanding of gravitation is merely the scientific hypothesis explaining various observations (like a certain little apocryphal tale about a certain apple hitting a certain famous scientist on his equally famous certain cranium). And, even if you do not believe in or do not understand the theory, you hardly float off the Earth's surface!

    Sometime tomorrow morning I plan to drop off a few more pieces of the Florida Archaeology exhibit at the Children's Museum. I will make sure I take some photos of the finished Glades Sequence Time Marker piece. It all has to be over there by sometime next week. Luckily, after tomorrow's delivery there will only be a few final pieces to finalize, mainly text on faunal bones and European contact. As soon as that is all finished, everything for the FAU library will need to be readied.
  16. Neanderthal Evolution and Glades Pottery Sequence

    Posted 1 year ago
    Greeting once again,

    I have been going over the material for the discussion I will be leading at the GCAS meeting, and I think this should be a good one. As I said before, it is based on the paper I gave at the 7ICVM. Basically, I trace the evolution of the Neanderthals from their ancestors, Homo heidelbergensis, through the accumulation of apomorphic (unique) 'Neanderthal' traits, and end with the appearance of some intriguing 'modern human like' features that appear in the very late Neanderthals. In the original paper I gave three possibilities for the appearance of this more gracile physiology: 1) adaptation to a similar environment as moderns (convergence), 2) interbreeding with moderns, and 3) tool traditions, i.e. the decreased use of the teeth as a 'tool' resulting in a reduction of facial prognathism (sticky-out-ness), with the resultant increasingly 'modern' face. I lean towards 3, but with some possibility of 2 thrown in.

    On a totally different track, last night I laid out the materials for the 'Glades Sequence/Time Markers' part of the Children's Museum exhibit. Nothing has been stuck down yet, and infact I still need to mount at least one piece of Glades I pottery (the one still in the bag), but I think the layout is looking good. Oh, and since I took the photo I decided to alter the two charts, the one on the left of the poster now has Glades I (red) at the top, and Glades III (green) at the bottom, and the Calendar Date and Glades Sequence has been flipped on the one on the right of the poster. I think that makes them both fit better with the layout of the pottery pieces. Another, half-sized poster board will be added to the right of this piece to explain what a ‘time marker’ is and how it relates to the Glades pottery sequence.

  17. Busy, Busy, Busy

    Posted 1 year ago
    Hi all,

    Recently, I have been very, very, very, busy, busy, busy. What am I working on?

    Well, first we have our February Gold Coast Anthropological Society meeting on Wednesday the 7th. I will be leading the after-meeting discussion on Neanderthal Evolution. This particular topic was chosen to compliment the upcoming Darwin Day event at Flamingo Gardens (but more on that soon). I have designed 5 posters that I will be using during the discussion, along with the museum's David E. Crawley Neanderthal Collection of replica skulls. Previously, I presented information on this subject at the 7th International Congress of Vertebrate Morphology. I always meant to submit a paper on the same subject, but never got around to finishing it. Still, the PowerPoint presentation I used at the 7ICVM was a great source for making these posters.

    Click to Enlarge










    Next up, we have Darwin Day at Flamingo Gardens on February 11th. I am also giving a lecture here; this one is on the 'physical evidence' of evolution. I have the outline for that presentation finished, and just need to fill in some of the details. I have also made two poster-size advertisements for our museum’s T-Shirts. Hopefully, some people will like the designs I put together.

    Third, by February 14th I need to have finished everything for the Florida Archaeology exhibit at the Children’s Museum. Why by that date? Because that is the day the exhibit is going to be installed. Then, on February 25th we have the opening event for that exhibit. There will be a number of activities including simulated artifact digs, how to use an atlatl, a guided tour through the exhibit, coloring now-extinct Pleistocene mammals, and designing your own pottery type.

    Finally, by February 27th everything for the FAU Library Florida Archaeology exhibit must be ready to be installed. At that point I need to work on the material for the lecture I will be giving on the same subject at the library on March 21st.

    Did you follow all of that?

    Still, the good news is that I am quite deep into finishing these various projects. It is amazing what a little time and a little hard work will do.
  18. Comp Study Ph.D., T-Shirts, Darwin Day, Kid’s Museum

    Posted 1 year ago
    Greetings all,

    Early this week I dropped off all the required material at the Comparative Studies office. They now have my application, 3 letters of recommendation, GRE scores, transcripts, and my letter of intent. Frustratingly, all that can be done now is to wait and see.

    The good news is that we have sold 7 T-Shirt since putting up all the designs on Wednesday. Unfortunately, the bad news is that those were all ‘internal’ sales to myself and some colleagues who will be helping at the upcoming Darwin Day event. However, the good news is that we will all look spiffy in out new PBMNH-Darwin Day 2007 shirts.

    Speaking of Darwin Day, I have begun to finalize the details of my lecture at that event. After the intro talking about evolution, selection, genetics, etc, I will cover three ‘examples’ of ‘physical evidence’ for evolution. I am planning to review the evolution of the Neanderthals using the replicas available through the David E. Crawley collection. Next, I will talk about something at the genetic level, probably cystic fibrosis and its relation to plague. Finally, I thought I would end on Darwin’s finches. The lecture itself will end on universal common descent, because I like that topic and I think it is quite intellectually provocative.

    Finally, I drove to Target yesterday to get the final supplies I needed to complete the exhibit at the Children’s Museum of Boca Raton. What did I need? 4 x posterboard, 1 x tape, 1 x glue, and 1 x colored paper. It is amazing how glue, tape, paper, and a little bit of work can transform mere bagged artifacts into exhibit-level materials.
  19. Museum T-Shirts

    Posted 1 year ago
    Hello all,

    The museum has a number of events and activities coming up, so I decided to put together some T-Shirts to offer for sale to the attendees. I have completed some basic museum shirts, and some specific designs for Darwin Day. These designs have been uploaded to CafePress. I hope to add more as I have time.

    So far, there are six different designs. Each design is available in a variety of different shirt styles. If you happen to like any of the designs, just click on the photo and it will take you to the appropriate place to chose the style you like and order the shirt.

    This first one is straightforward, a The Palm Beach Museum Natural History logo shirt.


    Some of you regular blog readers may remember this one, our Eat, Sleep, Dig shirt.


    Another simple shirt with our logo and Darwin Day 2007.


    This one is a little bit silly, but still amusing.

  20. Museum Blogs and Children's Museum Delivery 2 Photos

    Posted 1 year ago
    Hello all,

    I dropped off some of the material for the Comparative Studies program; however, they are still waiting for one or two other items. I will have to give FAU a call to make sure that everything is received and sent to the correct office by the deadline.

    On a different note, this blog has appeared on Museum Blogs. I am hoping we might get more exposure for both my work and the museum. And, if you found this blog through Museum Blogs; a big welcome to you.

    CLICK TO ENLARGE


    I have dropped off more material at the Children’s Museum of Boca Raton. While the official opening (and the associated opening events and activities) is not until February 25th, the exhibit itself will probably be installed by the middle of the month.

    CLICK TO ENLARGE

    First off, here is the box of stuff. I have purposely designed everything to fit inside two standard plastic boxes. After this exhibit has finished at the Kid’s Museum, I am hoping we can update (and even improve) a few things and we have a ready made traveling exhibit.


    This is a general overview of the material I took over there. You’d be surprised what you can fit inside one box!


    Both of these photos show the general orientation the items will take on the exhibit shelves. On the left we have a replica megalodon tooth and a replica manatee rib with example fossil rib fragments. On the right are a juvenile mastodon tooth and a fragment of an adult mammoth tooth.


    Obviously, as an exhibit on archaeology, we have to have some human-made tools. The atlatl was used by the Native Floridians to hunt mastodons and mammoths, along with many other animals.


    This is everything that I have taken over to the Kid’s Museum, including the material from the first delivery. I’d estimate this is about 2/3’s of the total inventory that will be on display.


    Finally, while I have previously shown the area where the exhibit is going in, along with the tall case, this smaller case will also be used. The plan is to have faunal bones on the bottom shelf, tools on the middle shelf, and Spanish Contact on the top shelf.
  21. Letter of Intent, A Philosophical Story, and Those Crazy Hobbits

    Posted 1 year ago
    Hi all,

    I have all-but finished the letter of intent. I will be hand delivering it, along with a 25-page writing sample, late tomorrow morning. Hopefully, as long as the last letter of recommendation makes it in, I should make the funding deadline.

    I was originally going to post the completed letter here, but after some discussions with other folks, I am wondering if that is such a good idea. I do not think someone would steal the ideas themselves; I would be surprised to find anyone else who wants to take on this immense task. However, the paper itself could be plagiarized. What I mean is that if someone needed a paper for a particular social science class, they may take the letter and hand it in for credit. It would be kind of like those pay-for-paper website, just as a free-bee.

    Infact, I have seen that very thing happen before when a colleague was TA-ing for a Philosophy class. The Professor had assigned the class a paper on a particular subject. Right now I forget what that subject was, but lets call it Modern American Philosophy. One student in the TA's section handed in a paper where the body was composed of Ancient Greek Philosophy (and was extremely well-written), and only the introduction and conclusion mentioned the assigned topic (and the spelling and grammar were atrocious). When I was shown the paper I immediately saw what the student had done. They found paper on Philosophy and simply added a brief paragraph on the Modern American Philosophy at the beginning and at the end, thereby trying to pass it off. How was I able to prove this had occurred? Well, it took me about 15 seconds of searching on the web. Using a search engine, I typed in the first sentence of the second paragraph and BAMM found the original paper written by a Ph.D. holding Professor at another university. Somehow, I do not think a person who already has a doctorate in Philosophy is going to take an undergraduate introductory class in that same subject. Of course, you may wonder why someone would risk their college career? Most schools have a zero tolerance policy on plagiarism (you either fail the class, or are completely kicked out of the university). In this case it was simple, there was no interest in pursuing the student, despite the obvious guilt. To me this sends a clear message, it is okay to steal others ideas and writings without credit. While I think knowledge itself should be freely distributed, the attribution of credit is crucial. I do wonder what this lax attitude will do to the academic world?

    The upshot is that I will not post the whole letter of intent. However, I may post some excerpts, may the wrap-up from the last paragraph.

    On a different note, I found an article on the BBC News website, which also has some interesting, if negative, insights into the research world. And, you will notice that I have given full recognition as to the original source of this material, it is amazing how easy it actually is to give credit.

    Hobbit cave digs set to restart

    The Archaeologists who found the remains of human "Hobbits" have permission to restart excavations at the cave where the specimens were found.


    Indonesian officials have blocked access to the cave since 2005, following a dispute over the bones.

    But Professor Richard "Bert" Roberts, a member of the team that found the specimens, told BBC News the political hurdles had now been overcome.

    The researchers claim that the remains belong to a novel species of human.

    But some researchers reject this assertion, claiming instead that the remains could belong to a modern human with a combination of small stature and a brain disorder.

    Finding other specimens in the cave, particularly one with an intact skull, is crucial to resolving the debate over whether the Hobbit's classification as a separate species - Homo floresiensis - is valid.

    Political hurdle

    But access was reportedly blocked due to political sensitivities.

    "This year we will back in Liang Bua again, back in the cave where we found the Hobbits," said Professor Roberts, from the University of Wollongong in Australia.

    "This is good; we've now managed to get over the political hurdles that had been put up. We'll probably be in there towards the middle of the year."

    The Hobbit's discoverers are adamant it is an entirely separate human species that evolved a small size in isolation on its remote Indonesian island home of Flores.

    Skeletal remains were discovered by an Australian-Indonesian research team in Liang Bua, a limestone cave deep in the Flores jungle, in 2003.

    Researchers found one near-complete skeleton, which they named LB1, along with the remains of at least eight other individuals.

    Vertically challenged

    LB1 was an adult female who lived 18,000 years ago who stood just 1m (3ft) tall and possessed a brain size of around 400 cubic centimetres (24 cubic inches) - about the same as that of a chimp.

    Long arms, a sloping chin and other primitive features suggested affinities to ancient human species such as Homo erectus and even earlier ones such as Homo habilis and Australopithecus.

    These observations could imply that humanlike creatures - hominids, or hominins - reached island South-East Asia much earlier than had been thought.

    The find caused a sensation when it was unveiled in 2004, because it suggested human evolution had been much more complicated in South-East Asia than previously imagined. It also showed that another species of human had survived into "modern" times.

    Mike Morwood, director of the excavation, told BBC News the remains at Liang Bua could be the tip of the iceberg: "South-East Asia and East Asia are going to yield an awful lot of surprises and it's going to make a major contribution to our understanding of hominin evolution."

    But not all researchers were happy about this hand grenade being tossed into one of palaeoanthropology's hallowed vestibules.

    Professor Teuku Jacob, based at Gadjah Mada University, in Yogyakarta, Indonesia, contended that the bones of LB1 could have been those of a pygmy person with the condition microcephaly, which is characterised by a small brain.

    Bone damage

    In 2004, Professor Jacob - known as Indonesia's "king of palaeoanthropology" - took the bones away from their repository in Jakarta to his lab in Yogyakarta, 443km (275 miles) away, against the wishes of the researchers who found them.

    They were eventually returned. But the discoverers claimed the bones were extensively damaged in Jacob's lab during attempts to make casts.

    The damage included long, deep cuts marking the lower edge of the Hobbit's jaw on both sides, said to be caused by a knife used to cut away the rubber mould.

    In addition, the chin of a second Hobbit jaw was snapped off and glued back together. Whoever was responsible misaligned the pieces and put them at an incorrect angle.

    The pelvis was smashed, destroying details that reveal body shape, gait and evolutionary history.

    After the accusations surfaced, Professor Jacob denied damaging the remains, telling USA Today that breakages could have occurred when the bones were being transported from Yogyakarta back to Jakarta.

    Excavations at Liang Bua were reportedly blocked because Indonesian government officials would not issue exploration permits for projects that might prove Professor Jacob wrong.

    Momentous discovery

    But the remaining issues now appear to have been smoothed over.

    "It's now a matter of getting everything organised so we can start digging again," said Professor Roberts.

    "You've got to get there in the dry season; in the wet season you can hardly drive to the site and when you are there, there are puddles of water all over the floor - so it's got to be dry to sensibly dig holes."

    Speaking to BBC News before permission was given to restart excavation, Mike Morwood, from the University of New England, Australia, was optimistic about future research into H. floresiensis and the record of human occupation in island South-East Asia.

    "This particular discovery seems to have prompted people to rethink what it is to be human, the relationship between brain size and behaviour, and whether hominin populations have been insulated from environmental factors. This indicates that they haven't.

    "It also raises questions about the colonisation capabilities of early hominids. What are they doing on Flores and what are they almost certainly doing on other islands in South-East Asia."

    It is still not known how hominids travelled by sea between these islands. Building watercraft may have been a skill too advanced for them.

    So natural catastrophes such as tsunamis have been invoked by some researchers to explain their distribution. Hominids could have clung to trees as they were washed out to sea, eventually arriving on the shores of other islands.
  22. Letter of Intent, Kid’s Museum Exhibit, Darwin Day Update

    Posted 1 year ago
    Greeting all,

    I am close to finishing the revision of the third version of the Letter of Intent. I am relatively happy with this current rendering. I have had a lot of input from other folks (which is appreciated) and I think I have been able to fix some minor (but nagging) issues. Once I complete this, I will probably post it here.

    I spent most of the rest of today working on the exhibits for the Children’s Museum. I am pleased with how they have turned out, considering the limited time and budget. I will post some pictures when I have time (and when I have actually taken said photos). However, I can tell you that in total I have mounted a megalodon tooth replica, a manatee rib replica, three manatee rib fossil fragments, a partial mammoth tooth, a juvenile mastodon tooth, and an atl-atl (that is in addition to the material already delivered to the Kids Museum). These items are all on primary color backgrounds, ensuring that they do not blend into the scenery. The associated signage is almost ready too (and that will be posted here at some point). While this exhibit is under the umbrella of the PBMNH, it has been more a personal project to actually discover by doing. All in all, I am quite thrilled and I believe I have learned something too.

    Finally, early this morning I responded to an email from the organizer of this year’s Darwin Day event. They want me to do something on the ‘physical evidence,’ which must be related to the fact that I have studied physical anthropology (and probably not because I used to enjoy some of the games in physical education back in school). While I have yet to really work on the lecture I will be giving, I had some general ideas that I laid out in this excerpt from the email:

    I have not had a chance to finalize and write down details yet, but I should be able to do a few good things with the 'physical evidence.' What comes immediately to mind is a general introduction to Selection, with a brief mention of the need for Variation, along with Artificial and Sexual Selection. Once everyone is up to speed, it would be followed by in-depth examples of Natural Selection drawn from several areas (Darwin's finches, Neanderthals, etc). I would also like to include one genetic-level example (Cystic fibrosis, sickle-cell disease, etc), because I think it is important to show how well Darwin’s work melds with modern Genetics. The conclusion must end on Universal Common Decent, because I have always found the interconnection of all life to be a powerful concept (which might dovetail well into the later talk on the ‘tree of life’).

    Indeed, probably about half of this material will be adapted from my extant Neanderthal lecture, and a further portion from other general Evolution talks I have previously given. Despite these already prepared elements, I do plan to do some intensive reading over the weekend. You never know what new information might be out there.
  23. GCAS Cookout: Photos

    Posted 1 year ago
    Hello all,

    Here are the photos from our recent GCAS cookout in the park.

    CLICK TO ENLARGE

    We arrived at Hugh Taylor Birch State Park in the later morning to start setting up. As you can see we brought coolers, instant grills, atl-atls, spears, and a cricket set.


    The instant grills worked fantastically. We had hamburgers, hot dogs and chicken all grilled to perfection.


    Almost the instant we put the food on the grill, we had a visitor. Unfortunately, this raccoon was too accustomed to human presence, and we guessed others must have fed him in the past.


    After we ate we decided it was time for some fun and games. First, we tried out the atl-atl (spear-thrower). It took a little bit of practice, but some of us were getting both decent distance and accuracy.


    We did have one small disaster involving a spear. The atl-atl was able to throw this spear with enough force to cause it to snap in half when it hit the ground.



    We all took turns at cricket; although, we used a tennis ball because we didn’t want out-of-control cricket balls injuring anyone.


    All in all, it was a great day out.
  24. Children’s Museum Delivery 1: Photos

    Posted 1 year ago
    Hello all,

    As promised, here are some shots of the first lot of material we took over to the Kid’s Museum in preparation for the upcoming exhibit. You can also see the packages of bulk fossils that we are going to offer for sale to the kids. I also took some pictures of where we are putting in this little installation. Although, there will be another case put in before we are finished, and both of these cases will be fronted with plexi-glass. Still, I think it is a good corner.

  25. Letter Update and European Hominins

    Posted 1 year ago
    Hello one and all,

    I am still working on that letter thing. As this point I realize that I have been calling it a variety of different names, including a Letter of Intent, a Statement of Purpose, a Statement of Intent, and a Letter of Purpose. At least it seems I am more settled on what I actually want to say vs. what it is called. I wrote a first draft that got to about 40% complete before I pulled the plug. It was just not flowing properly, so I took the basic structure and one or two complete sentences and started again. The good news is that as of right now I am at about 80% on the second draft. I hope to have a complete draft done tonight or early tomorrow morning. At that point I am going to send it out to a few people for review.

    On a different note, I found an interesting article on the BBC News website.

    European skull's evolving story

    The earliest modern humans in Europe were short of being the complete article, according to a study of a fossilised skull from Romania. The 35,000-year-old cranium discovered in Pestera cu Oase in the west of the country shows an interesting mix of features, say scientists. Whilst undeniably a Homo sapiens specimen, it has some traits normally associated with more ancient species.


    The skull is reported in Proceedings of the National Academy of Sciences.

    Dr Helene Rougier, from Washington University in St Louis, US, and colleagues say the fossil suggests the first modern humans to enter Europe continued to evolve after they had settled.

    H. sapiens is thought to have emerged in Africa more than 150,000 years ago before spreading out of the continent and arriving in Europe less than 50,000 years ago.

    Ongoing story

    The reconstructed cranium - known as Oase 2 and found in a Late Pleistocene bone bed containing the remains of cave bears - comes from the earliest stages of the occupation.

    In addition to its large face and retreating forehead, the specimen has the largest cheek teeth so far known for an otherwise anatomically modern human, the team reports.

    The scientists say the mixture of modern and archaic features could have resulted from interbreeding between H. sapiens and the older Neanderthal humans ( Homo neanderthalensis) who were already in Europe.

    But, they add, the fossil may simply also be a case of ancient traits reappearing in a modern human, or even an indication that science has not yet been able to study enough early modern people to fully understand their diversity.

    Co-author Joao Zilhao of the University of Bristol, UK, said: "The ultimate resolution of these issues must await considerations of larger samples of European early modern humans and chronologically intervening specimens."

    And team member Erik Trinkaus, also of Washington University, commented: "I think that what this find really shows is the ongoing nature of human evolution. Technically, this skull is a modern human, but humans as we know them today have evolved considerably since then."
