New Study Reveals Complex Interactions Between Early Humans and Neanderthals

Recent genetic research reveals new insights into the extinction of Neanderthals and their interactions with early humans. A groundbreaking study published in Science uncovers multiple DNA exchanges over 250,000 years, challenging previous notions of human evolution and migration. This research highlights the complex relationships between different hominin species, suggesting that Neanderthals were not isolated but engaged with modern humans and other archaic species like the Denisovans. These findings reshape our understanding of human ancestry and the genetic legacy that influences us today.

Scientists Successfully Replicate 52,000-Year-Old Woolly Mammoth DNA
