Princeton Study Maps 200,000 Years of Human–Neanderthal Interbreeding (Princeton University Science Daily, 7/14/25)
Now, a group of researchers made up of geneticists and artificial intelligence specialists is uncovering new layers of that shared history. Led by Joshua Akey, a professor at Princeton’s Lewis-Sigler Institute for Integrative Genomics, the team has found strong evidence of genetic exchange between early human groups, pointing to a much deeper and more complex relationship than previously understood.
“This is the first time that geneticists have identified multiple waves of modern human-Neanderthal admixture,” said Liming Li, a professor in the Department of Medical Genetics and Developmental Biology at Southeast University in Nanjing, China, who performed this work as an associate research scholar in Akey’s lab.
