Recent evidence has shown that a small percentage of human DNA is Neanderthal. This Neanderthal DNA entered the human gene pool between 80,000 and 50,000 years ago.
While human DNA may contain traces of Neanderthal ancestors, mitochondrial DNA from Neanderthals has not been found in humans. Mitochondrial DNA comes uniquely from your mother. Is it plausible that male Neanderthals were able to mate with female humans, but that the reciprocal cross was unable to occur?
Analyses of the Y chromosome suggest that we share a common male ancestor 59,000 years ago. Could this male ancestor have possibly been Neanderthal?
If our common male ancestor is neanderthal, and considering that the Y chromosome is transmitted uniquely through the paternal line, could it mean that men are more closely related to Neanderthals than women? Have men and women truly come from two different species?
