Quote:all non-African populations derive around 2 percent of their ancestry from Neanderthals, whereas substantial levels of Denisovan ancestry (around 2-4 percent) are only found in Oceanic populations

Quote:DNA suggests they may have given humans at least some immune system advantages, as well as red hair and a tendency to allergies.


Whatever DNA survived probably offers an advantage, or else it would have been weeded out by natural selection, the researchers say.

Big stretches of modern human DNA from people around the world are clear of any Denisovan or Neanderthal sequences, the researchers said. These are regions associated with language, as well as the tendency to autism.
