This week on The Naturalist, Bernie continues last weeks discussion on evolution and species formation with friend of the show Saul Scheinbach. Learn about new species being formed, including the Cackling goose and a new American cockroach right here in NYC. Find out about how species can now be identified by bar-codes and how migration patterns can change over time. It all starts and ends with Darwin, and Bernie & Saul explain why his “theory” of evolution is less of a theory and more of a big idea. This episode was sponsored by S. Wallace Edwards.

“There is a new species of American cockroach forming right here in New York City!”

“Migration is based on genetics but changes very easily.”

“I like to call it Darwin’s “big idea” instead of a theory.”
