Palaeo After Dark

The gang discusses two papers that use functional morphology to determine when echolocation evolved in two groups of mammals, whales and bats. Also, Curt rattles off a wikipedia page on hamburgers, James fights against physics, and Amanda would rather talk about how terrifying Basilosaurus is. Also, to cut this off at the pass, a correction. Bats are the "SECOND" most diverse mammal group and rodents are the most diverse.
