Is evolution a fact? How do the claims of creationists stack up against the fossil record and the actual science? Dr. Donald Prothero presents the evidence in a presentation based on his 2007 book (and more recent findings). Prothero is a paleontologist, geologist, author and science educator. He holds a Ph.D in geological sciences from Columbia University, and he has authored over 300 scientific papers and 30 books. He is currently a research associate in vertebrate paleontology at the Natural History Museum of Los Angeles County.
