How a Ptarmigan Changed History

You misunderstand me. The Neanderthal DNA in most modern humans is all from male lineages. We'd expect some evidence that Neanderthal females bred with expanding Homo sapiens..

Yes, there hasnt been any Neanderthal mitochondria found, which, as you say, implies all interspecies sex was Neanderthal male on Sapiens female. Otoh, there hasnt been any Neanderthal Y chromosomes found either, which suggests... what? Im not sure? Maybe hybrid males were infertile?
