The whole of natural history fascinates me, but everyone has their own favorite topics, and one of the most intriguing subject areas (to me, at least) is predator/prey interactions. Herbivores are interesting in their own right, surely, but for me it is the predators that are the most thought-provoking and impressive. Given this proclivity to ponder carnivory , I've chosen to write up my term paper for a seminar course I'm currently taking (Topics in African Prehistory) on the entrance of hominins into the "Carnivore Guild," especially in terms of hunting small prey in forests, scavenging…

Today's photo, like yesterday's, was taken at the Philadelphia Zoo, and I was fortunate enough to be able to catch the Hippos (Hippopotamus amphibius) as they were entering the water. I'm sure everyone has heard of their aggressiveness via television documentaries and other sources, but few have heard of the fact that hippos sometimes consume flesh. While hippos occasionally nibble on or play with carcasses in African waterways, in severe drought conditions they sometimes kill prey (as in one account of an impala running into the water to avoid Wild Dogs, only to be killed and consumed by…
laelaps | November 6, 2007Back when I was a blogging greenhorn, right about this time last year, an evangelical YEC thought he had come up with an intellectual coup de grâce to make me see "the light"; "Antony Flew believes in a god, so there." (Ok, so I'm paraphrasing just a bit) Chalk it up to ignorance, but I had never even heard of Antony Flew, and saying that he believed in a deity had about as much effect on me as saying "Charlie Parker thought the sky was purple" (and given his problems with drug addiction, maybe he sometimes did). Still, over and over again Christian apologists have invoked Flew's name and I…
laelaps | November 6, 2007I apologize, dear readers, that today I probably won't be able to keep up with my more usual prolific rate of posting. The reasons for this today are as follows;
I have two major exams today, one in my "Soils & Water" "Soils and Society" class and my Computers midterm (which for some reason was scheduled to start at 10 PM).
I occasionally experience dizzy spells/lightheadedness during this time of the year, today being one of those days.
I have a weekly presentation to give tomorrow about meat-eating in early hominids that I haven't started yet. I have no doubt that I'll be able to…

The Fishing Cat (Prionailurus viverrinus) is a very interesting Indonesian species of felid that doesn't seem to mind getting wet. Living on the margins of rivers, swamps, and smaller bodies of water, these cats often swim and (as their name implies) are quite fond of freshly-caught fish. Indeed, they've become more adapted to this type of habitat and lifestyle than other cats that are just occasional visitors to the riverbank, developing larger inter-digital webs than other cats to help it get a grip on muddy surfaces (the other branch of the Carnivora, the canids, includes the Bush Dog of…

The fiberglass skull of Barnum Brown's second Tyrannosaurus rex fitted on the revised mount now standing on the 4th floor of the AMNH.
The AMNH in New York is home to some of the most impressive biological collections in the world, the institution playing host to various students of natural history. This tradition of allowing researchers and graduate student access to the collections is now taking another step forward with the opening of the Richard Gilder Graduate School, currently offering a Ph.D. in Comparative Biology. As the "Welcome" statement from John J. Flynn states, much of…

Even though I didn't get to go to SVP this year, my friends Julia and Neil were in attendance and were kind enough to send me a *signed* copy of Don Prothero's newest book, Evolution: What the Fossils Say and Why it Matters. Although I was already in the middle of a book when Prothero's book arrived at my door, I dropped what I was reading and started tearing through the glossy pages, and I have to say that I was impressed. Aside from the excellent illustrations by the talented Carl Buell (plus tons of photographs and other diagrams), Prothero's book doesn't hold back when it comes to…

A mother Tyrannosaurus rex and her offspring at the end of the WWD live show.
Robotic dinosaurs have long been a thorn in the side of students of paleontology; the rigid, roaring robots of the "DinoMotion" craze of the 1990's did little more than get more people into museums without providing them with any actual information about the extinct animals. Stephen Jay Gould laments this theme park treatment of dinosaurs in his essay "Dinomania" (compiled in Dinosaur in a Haystack);
As a symbol of our dilemma, consider the plight of natural history museums in the light of commercial dinomania.…
laelaps | November 5, 2007I'm a little late on this, but if you haven't already, head on over to Greg Laden's fancy new digs here at ScienceBlogs! Be sure to stop by the Sandwalk, too, as it's celebrating it's first blogiversary.
Update: Also, Chris is celebrating his 100th post with a brand new carnival about classification and systematics, Linnaeus' Legacy! Be sure to check out the taxonomic goodness.
Update the 2nd: Be sure to say "hi" to another brand new member of the ScienceBlogs community, The Quantum Pontiff, too.
laelaps | November 5, 2007For all of you who enjoy the various photographs I post here every day, I've now opened a CafePress store featuring some prints, mugs, and calendars emblazoned with some of the best photographs I've taken in 2007. There are shots of various creatures, big and small, from the Bronx, Philadelphia, and National Zoos, although I hope to soon have a "Best of 2006" calendar with some earlier (but no less impressive) shots. If you'd like to take a look, click here.

The American Black Bear (Ursus americanus) is so common in northern New Jersey that many people don't need to go to a zoo in order to see one. Although there have been occasional sightings of the animals in New Brunswick, I've only once seen a Black Bear in the wild, a large individual that quickly ran off through the forest as soon as I saw it. Still, the Black Bear population in New Jersey exponentially increased in a very short period of time, many state conservation and wildlife agencies coming under fire for supporting or not supporting a bear hunt (at least one official left their…

Today's photo comes from the National Zoo in Washington D.C., the only place where I have seen the Gavial (Gavialis gangeticus) in captivity. This crocodylian is one of the most endangered in the world, and the National Zoo has a male and female pair (and I can only assume that the zoo staff hopes the two will breed). The above photograph is the female, males of the species having a bulbous growth or "ghara" on the tip of their snout. Outside of being a signal as to which sex an adult belongs, the ghara is also used in vocalizations the male makes and blowing bubbles during mating displays,…

During the 1990's I can scarcely remember a time when one television station or another wasn't playing at least one of the four JAWS movies, TBS, TNT, or WPIX often devoting an entire day to films about killer oceanic creatures. Still, of the four films JAWS 3 (or 3-D, if you like) was one of the b-movies that was always making the rounds, and it's gratuitous special effects make it an easy target for this week's cheesy movie selection.
Although I didn't realize it as a kid, JAWS 3 picks up the story of the Brody family at a Sea World theme park (Sea World Orlando, a landlocked theme park,…
laelaps | November 3, 2007After many false starts I've actually started to write my "treatise" on evolution, some of the pages I've been turning out being in note form (I want to get the ideas down and then fill in the exact details later when I can pick up the proper reference books from the shelf) while others resemble actual passages and are in a near-finished form. My work isn't going to be a chronological overview of the history of life like many other books, but will instead take a more personal approach reflecting how I've come to understand evolution and how it proceeds. Differing rates of change, convergence…

Today's photo is of a Lesser Tree Shrew (Tupaia minor), sitting still for a split second allowing me to get a somewhat blurry shot. I wasn't initially thinking of putting this one up today, but I thought it would be a topical choice given a new study in Scienceout this week that suggests Colugos (Family Cynocephalidae) may be more closely related to primates than Tree Shrews (Order Scandentia). Using partial genomic data from both groups (plus primates), the research team found that the colugos were more closely related to primates than the tree shrews, although we have yet to see if this…
laelaps | November 2, 2007Mark of SB's own Denialism Blog has asked other science bloggers who use animals in their research to speak up and discuss what they do either in their own posts in the comments. I do not participate in lab research involving animals, but I have taken an interest in the subject, especially when non-human primates are used. While I don't doubt the importance of animal testing, I do have reservations about the ethics of using non-human primates in medical research. This is not to say that I advocate the acts of terrorism by extremists as related in Mark's posts, but I do have concerns about…

Polar Bears (Ursus maritimus) have always been favorite animals at zoos and aquariums, but the current problem of anthropogenic global climate change has popularized them further by making them extinction's poster species. While many documentaries show the loss of ice as one of the primary factors that is threatening the bears, the overall rise in temperatures is having a more subtle (but widespread) impact on the unevenly distributed populations of bears. Polar bears have adapted to cold climate so effectively that they do not do well when temperatures exceeding 50 degrees Fahrenheit, and…
laelaps | November 1, 2007I still am a bit disappointed that I had to miss SVP this year, but fellow paleo-blogger Amanda has suggested that everyone who wants to attend the 2008 meeting put a little progress bar on their blog to remind themselves to start saving up for the trip (you can make your own using this word cash meter). I'm setting mine at $1,500, and although registration is only a fraction of this amount, I'm going to need to save a lot for gas, hotels, food, extra activities, the money I won't be making since I'll have to take off from work, and the armful of books I'm sure to come home with. Indeed, I'm…

A close-up B&W shot of the Willamette Meteorite. The holes the riddle one face of the meteorite were not caused by "cosmic collisions" but by the bolide rusting away in the ground prior to its removal from the Oregon soil (it consists of 91% iron).
Virginia Hughes is an editorial assistant here at ScienceBlogs who was especially helpful in moving Laelaps over to it's new home, and now she's brought her excellent writing to The Gist on Smithsonian.com. The first story? A 30-pound hunk of the Willamette Meteorite appraised at $1.3 million was withdrawn from auction after it failed to…
