Hour One: Paleontology and Anthropology News

Recent reports of fossil finds in Ethiopia may change the way scientists draw the human family tree. The fossils, over 5 million years old, give new information about the way early hominids moved and the habitats that they lived in. We'll find out more.

Plus, new research into the structure of dinosaurs' noses says that many depictions of the ancient creatures are all wrong. We'll talk about it. Call in with your questions and comments at 1-800-989-8255, and share your opinions online in our Listeners' Lounge (registration required)
