The title on NS is: "Missing Y chromosome kept us apart from Neanderthals" and that is importantly different from the title here on HN.
Only males have Y chromosomes so if only "Mutations in Y Chromosome made us separate species from Neanderthals" then female Homo Sapiens and Neanderthals would be genetically the same. I know I'm being a bit pedantic about the use of the word 'made' in the title but it seems important to me.
- danieltillett 11y agoIt is not that Africans females and Neanderthals are genetically the same, just that the genetic incompatibility between the two species appears to be sex specific. This is pretty common when different species hybridise. Haldane's rule covers why this occurs [1]. 1. https://en.m.wikipedia.org/wiki/Haldane%27s_rule https://en.m.wikipedia.org/wiki/Haldane%27s_rule
