Exploring Our Biological Inheritance: Carl Zimmer On Heredity

Inside our genomes, we carry information about our recent ancestors as well as ancient human history. This hour, we sit down with science writer Carl Zimmer to talk about his new book, She Has Her Mother's Laugh: The Powers, Perversions, and Potential of Heredity. We ask him what our DNA can—and can’t—tell us about where we’re from and who we are.Support the show: http://wnpr.org/donateSee omnystudio.com/listener for privacy information.
