Origin of Animal Body Plans/Leptoquarks

Last week, physicists operating a particle accelerator in Germany may have observed a rare particle that can't be explained by existing theories. In this hour of Science Friday, we'll talk about how this discovery could revolutionize physics. Plus, we'll hear from paleontologists about new research on the Cambrian explosion, a short period in evolutionary history when all the basic body plans of living animals appeared.

Guests:
Doug Erwin
Research Paleobiologist
Curator of the Burgess Shale Fossils
Smithsonian Insititution's National Museum of Natural History
