A jaguar (Panthera onca). From Flickr user Prosper 973.
One year ago this week Macho B was euthanized. He had been captured in mid-February of 2009, the only known jaguar living inside the United States, but after he was caught and fitted with a radio collar his health quickly deteriorated.…

Yellowstone National Park is an amazing place. I stayed there for three days longer than I had originally planned and I still was not ready to leave it. Even if I had spent another week there I still would not have seen all the natural wonders of the park, but fortunately the BBC recently sent film…

Here's another sneak-peek at Life (this time with David Attenborough's narration) featuring one of my most favorite canids, the Ethiopian wolf (Canis simensis). Enjoy!

An adult chimpanzee in Bossou, Guinea uses hammer and anvil stones to crack nuts as younger individuals look on. From Haslam et al., 2009.
Before 1859 the idea that humans lived alongside the mammoths, ground sloths, and saber-toothed cats of the not-too-distant past was almost heretical. Not…

Male (right) and female (left, with infant) friends in a population of Chacma baboons. (From Palombit, 2009).
Among other things, friends are people you count on to come to your aid when you need help. If you were at a bar and a stranger started acting aggressively towards you, for example, you…

Today is my 27th birthday. To celebrate Tracey and I were planning on visiting Philadelphia's Mutter Museum and the Academy of Natural Sciences, but given the deep accumulation of snow we thought better of going into the city. I can still celebrate by sharing something with you, though. Presented…

When it comes to nature documentaries the BBC's natural history unit is the best of the best. Over and over again they have produced top-notch programming, and their new multi-part series Life is perhaps the best I have ever seen. The series contains some familiar moments, such as a sengi…

Way back in 2007, when I was still a neophyte science blogger, Rutgers University philosophy professor Jerry Fodor published an op-ed in the London Review of Books called "Why Pigs Don't Have Wings." It was a critique of a straw man version of evolutionary theory characterized by a brand of…

A restoration of the giant, durophagous shark Ptychodus, courtesy paleo-artist Matt Celeskey.
The study of prehistoric sharks is no easy task. Specialists in other branches of vertebrate paleontology at least have the reasonable hope of discovering complete skeletons of their subjects; except…

The classic monster film…

Detail of a Charles R. Knight mural depicting a family a mastodons.
Fossils often turn up in unexpected places. As people have dug swimming pools, tilled farms, blasted through mountains, and quarried the land for minerals traces of ancient life sometimes come to the surface, from isolated shark…
