The Evolution of Whales ~ with Professor HANS THEWISSEN
Show Notes Chapter Markers

J. G. M. 'Hans' Thewissen, Ph. D. Anatomy Professor at Ohio University,  studies fossil cetaceans in order to answer questions about the evolution of whales -- in particular, about how whales originated from land animals.

MARK from Evolution Soup talks to Hans about his early discoveries, fossils of proto-whales that lived partly on land, and the features we can point to in whale anatomy that display the transition from land to water over 50 million years.

Illustrated throughout with artwork from Paleoartists NOBU TAMURA and LUCAS LIMA.

Support the show

Did you always have an interest in evolution and in particular, the evolution of whales?
When did we first start to understand the evolution of whales? And where were those first evidences found?
Why might these creatures have decided to spend more and more time in the water, and – most importantly - how do we know that they are related to whales?
One way to see that whales are related to mammals is to look at their skeletons. The most obvious thing we can see is what appear to be remnants of hind limbs, isn’t that right?
Cetaceans have a particular kind of ear bone that tells us a lot, correct?
As we look along the evolutionary line of whale ancestors, we can actually see how nostrils evolved to become blowholes. Can you tell us about that?
How does embryology help us in our understanding the evolution of whales?
Thank you so much for coming on to the show and hopefully we can do a follow-up interview one day soon and cover even more ground!
