What Neanderthal DNA Is Doing To Your Genome

The video explores the intertwined history of humans and Neanderthals, highlighting how Neanderthal DNA, which constitutes about 2% of the genome in many modern humans, influences gene expression. This DNA can affect traits like height, immune response, and disease risk. Research from the University of Washington shows that Neanderthal genes are expressed differently in various tissues, particularly less in the brain and testicles, suggesting rapid evolution in these areas. The findings indicate that ancient interbreeding continues to impact human biology today, and future research will explore similar effects from Denisovan genes.
