One of the most enduring questions in science is how did we become human. Fossil bones of our ancestors tell part of the story. But researchers at Kent State University have discovered another piece of the puzzle by comparing the brains of humans with other primates.

In this week’s Exploradio, WKSU’s Jeff St.Clair looks at the neurochemical changes in our distant past that became the turning point in human evolution.

A new book by an Ohio author unravels what used to be one of the greatest mysteries of science. It’s the story of how whales and dolphins came to be fully adapted to aquatic life. 

In this week’s Exploradio, WKSU’s Jeff St.Clair talks with the fossil hunter who traces the path whales walked in their journey from land to the sea.
