Denisovan DNA influences the immune systems of modern Oceanians - but researchers aren't sure why
A new study published in Science reveals that DNA inherited from extinct Denisovans continues to influence the immune systems of modern-day people in Oceania. Researchers identified over 3,000 genetic variants that help regulate immune responses, though the specific evolutionary benefits remain unclear.
Why it matters
Understanding how ancient human DNA affects modern biology provides deeper insights into human evolution and immune system functionality.
Genes inherited from the now-extinct Denisovans are actively playing a role in the immune system of some people from Oceania.
