I was led to wondering why didn't the Australian aborigines also develop lighter skin if the UV thesis is valid. But checking my globe I see Oz is located between the 10th and 40th parallels in the South, while most of Europe is above the 40th parallel in the North.

I now am curious if the DNA samples from Neanderthal and Denisovan sites provide enough information to examine the genes/alleles associated with skin color. Those species of course preceded homo sapiens by several 100 thousand years.
Thanks for this feedback. Now I suppose I need to track down the source that claimed the skin color change happened more rapidly and recently.
A longer term and time does seem to be more reasonable.
Perhaps you know the answer to the following question? Is there any archeological or other evidence that the interbreeding occurred via consensual relationships vs. via rape? I am skeptical that the relationships were consensual and friendly, compared to the many other expressions of "kumbaya" I have seen or implied. More utopian thinking on someone's part? My suspicion is that the males of either/ both subspecies initiated the genetic transfer without any concern for follow-on protection of any offspring thereby occurring. The family group of the raped female would have had to take on that burden.
Great idea. Maybe someone has explored that avenue already?
But if so I suspect we would have already heard about such a sensitive result. Conversely, I gather if that Y-mDNA characteristic was not observed, no one would think it odd to have neutral expected mixes and would believe consent was typical?

Now you’ve got me curious too! Thanks for a thoughtful discussion.
