Surprise! As a special holiday treat, the SAPIENS team is presenting this unedited conversation between SAPIENS host Chip Colwell and acclaimed science journalist Carl Zimmer about DNA, identity, and heredity. This conversation was previously excerpted in our episode “Is Your DNA You?” It took place in front of a live audience at the Denver Museum of Nature & Science on June 20, 2018. Carl Zimmer’s new book is She Has Her Mother's Laugh: The Powers, Perversions, and Potential of Heredity. Learn more about Zimmer’s work at carlzimmer.com.
