400,000-year-old teeth reveal a stunning twist in human evolution
Ancient human species thought to be extinct left a genetic legacy in people alive today through interbreeding with Denisovans. 400,000-year-old teeth found in China hold the key to this discovery. The findings suggest that early humans had a more complex evolutionary history than previously believed.
Why it's good news: It highlights the surprising and intriguing complexity of human evolution, challenging long-held assumptions about our ancient ancestors.
