#335 Neanderthals, Denisovans, and Us: How DNA Reveals Evolution

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.  Topics Covered in This Episode: How PCR revolutionized genetic research and our understanding of evolution What genetic diversity within African populations tells us about human origins Debunking myths about Mitochondrial Eve and human ancestry The genetic connections between humans, Neanderthals, and Denisovans How ancient DNA from medieval bones reshapes what we know about genetic bottlenecks Insights from the Pangenome Project and its potential to improve our understanding of genetic variation Relevant Episodes:  #326: How DNA Solves Crimes – The Forensic Science Behind True Crime (First Episode with Dr. Henry Erlich) #216 African American Ancestry with Nicka Smith #117 Dr. Janina Jeff on African Genomes #251 Diversifying Genetic Research with 23andMe (Explores African American Sequencing Project) #182 Dr. Eric Green on the Complete Human Genome Project and Pan Genome Project Resources and Links: Read Genetic Reconstruction of the Past by Dr. Henry Erlich Explore the National DNA Index System (NDIS) and CODIS The Innocence Project: Fighting wrongful convictions with DNA evidence GEDmatch and its role in forensic investigations Get ready, genetic nerds—another brand-new episode of DNA Today drops next Friday!
