>Note that this is after the Neanderthals went extinct. It follows that since there are people alive today with Neanderthal ancestry, there must have been people alive at the identical ancestor point who had Neanderthal ancestry and who have descendants alive today, and so by the definition of the identical ancestor point everyone alive today is a descendent of all such people. Not by definition. Adam is older than Eve which suggests we are descendant from multiple mate's of Eve. Some might have had neanderthal ancenstry, some might have not.
