Ancient DNA Unveils 7,000-Year Evolution of Early Europeans

TL;DR Summary
Researchers from The University of Texas at Austin and UCLA have used ancient DNA to uncover how Europeans adapted over 7,000 years, identifying genetic changes related to vitamin D production, lactose tolerance, and immunity. By analyzing over 700 samples from various historical periods, they revealed genetic adaptations that are no longer detectable in modern genomes due to genetic drift and population mixing. This study highlights the importance of ancient DNA in understanding human evolutionary history and how certain traits have evolved or disappeared over time.
