How does Neanderthal DNA affect modern human immunity?
Neanderthal DNA has been found to play a crucial role in modern human immunity. Studies indicate that certain genes inherited from Neanderthals enhance our immune response, helping us adapt to various pathogens. This genetic legacy may provide advantages in fighting off diseases, particularly in populations with Neanderthal ancestry.

What implications do these studies have for our understanding of human ancestry?
The latest research suggests a more intricate interbreeding timeline between modern humans and Neanderthals than previously believed. This complexity reshapes our understanding of human ancestry, indicating that our evolutionary history is intertwined with that of Neanderthals over thousands of years, rather than sporadic encounters.

When did interbreeding between humans and Neanderthals occur?
Interbreeding between modern humans and Neanderthals is believed to have occurred around 47,000 years ago. This timeline aligns with findings that suggest early modern humans migrated out of Africa and encountered Neanderthals in Europe and Asia, leading to genetic exchanges that have lasting effects today.

What are the latest advancements in ancient DNA research?
Recent advancements in ancient DNA research have allowed scientists to sequence the oldest known modern human genome. These breakthroughs provide clearer insights into the genetic relationships between early humans and Neanderthals, revealing the evolutionary advantages gained from interbreeding and the adaptation to harsh environments.

How does this research change our view of human evolution?
This research challenges the traditional view of human evolution by highlighting the significant role Neanderthals played in shaping modern human genetics. It suggests that rather than being a separate lineage, Neanderthals contributed to the genetic diversity and adaptability of modern humans, complicating the narrative of human evolution.
