This conversation is a follow-up to Episode #326: How DNA Solves Crimes – The Forensic Science Behind True Crime, where we explored the role of DNA in forensic investigations including the infamous O.J. Simpson case. Dr. Henry Erlich returns to the show to talk about human ancestry and evolution. 

Dr. Henry Erlich has authored over 450 publications and spent decades applying DNA analysis to criminal investigations, missing persons cases, and ancestry research. His work has helped us trace human origins, understand genetic diversity, and uncover how DNA links us to Neanderthals and Denisovans. His lab performed the first DNA case in the US and, in 1988, the first DNA exoneration. Erlich was the Director of the Department of Human Genetics and Vice-President of Discovery Research for Roche Molecular Systems, Inc until 2013. He is currently a Senior Scientist at Benioff Children’s Hospital Oakland Research Institute.
