The evolution of frogs

Jan 12, 2012

This week on the show: a former engineer calls for an investigation of the Callaway nuclear plant. Plus, new research may provide insight into how a species of treefrog evolved.

Hosted by Rehman Tungekar

Larry Criscione, a former engineer at the Callaway Nuclear Plant, is requesting that the US Nuclear Regulatory Commission look into possible violations of the operating license at the Callaway plant, owned and operated by Ameren Missouri. For KBIA, Janet Saidi has the story.

Plus, Carl Gerhardt studies treefrog communication at MU. New research from his lab shows that when it comes to mate preference in gray treefrogs, there may be more than meets the eye.

Correction: The audio version of this story suggests that humans underwent polyploidy. It actually occured in the early history of the vertebrates.
