A new analysis of DNA from ancient modern humans (Homo sapiens) in Europe and Asia has determined, more precisely than ever, the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,000 years — until Neanderthals began to disappear.
That interbreeding left Eurasians with many genes inherited from our Neanderthal ancestors, which in total make up between 1% and 2% of our genomes today.
A more precise timeline for modern human interactions with Neanderthals can help scientists understand when humans...
Jennifer Doudna, a UC Berkeley biochemist who shared the 2020 Nobel Prize in Chemistry for the invention of CRISPR-Cas9 genome editing, has been awarded a National Medal of Technology and Innovation, the nation’s highest honor for technological achievement.
Looking back on another outstanding year, Berkeley Letters & Science has compiled “24 L&S Highlights of 2024”—a recap of news, events, and announcements from the L&S community this year. Here are just a handful of the many stories demonstrating the extraordinary work of L&S students, faculty, staff, and alumni. Enjoy!
