This week on The Naturalist, Carol Butler takes a step back from bug-talk to share some interesting and bizarre facts about evolution and the human body. Find out how life has changed for us over time, and why standing up straight has forced us to adapt in many different ways. Ever wonder how our ancestors tore through all that tough meat before they had tools? Tune in and find out! This episode was sponsored by our friends at Cain Five Vineyard & Winery.
