Scientists studying the DNA of Neanderthals say they can find no evidence that this ancient species ever interbred with modern humans. But our closest ancestors may well have been able to speak as well as us.

evolution Neanderthal interbreeding genetics speech homo sapiensIn biology, a ring species is a connected series of neighboring populations that can interbreed with relatively closely related populations, but for which there exist at least two "end" populations in the series that are too distantly related to interbreed. Often such non-breeding-though-genetically-connected populations co-exist in the same region thus creating a "ring". Ring species provide important evidence of...
Between 1% and 4% of the Eurasian human genome seems to come from Neanderthals.

Neanderthal genetics human evolution genome interbreeding history DNAMating with Neanderthals and another ancient group called Denisovans introduced genes that help us cope with viruses to this day. Previous research had indicated that prehistoric interbreeding led to up to 4% of the modern human genome. The new work identifies stretches of DNA derived from our distant relatives.

Neanderthal Denisovan human evolution immunity interbreeding genetics cloningScientists have collected more evidence to suggest that ancient and modern humans interbred in Africa. Reanalysis of the 13,000-year-old skull from a cave in West Africa reveals a skull more primitive-looking than its age suggests. The result suggests that the ancestors of early humans did not die out quickly in Africa, but instead lived alongside their descendents and bred with them until comparatively recently.
