The first ones I believe were something like 50,000 years, which figure was merely chosen first by the dead guy who agitated for using mtDNA. Even in his lifetime he was notorious by the autogoal of referring to morphologists as being limited. His remark that pre-”modern” humans lacked speech, calling them “village idiots”, and pompously and ridiculously claiming that the ability to speak came from the mtDNA. Glad that jackoff died in pain, but I’m kinda mean.
Anyway, the 50K figure was considered kinda outta there even then, far too low; it went up pretty quickly to 70K, then 100K, and has continued to trend upward even using these “tools”. :’D I’ll go not very far into the oncoming lane and predict that these results will wind up nearing 2 million, and that this will happen within ten years.
Most other studies in the 1990s showed that the parsimoniousness of the tree that the low-end Replacement advocates claimed was total hogwash, IOW, they made the conclusion fit the original assumption. One merely needs to choose the data and the assumptions carefully enough, and anyone can sell anything to anyone. ;’)
The Neandertal Enigma"Allan Wilson had always been described to me in superlatives, such as 'one of the real geniuses in science,' or 'the most arrogant guy I know...' [H]e apologized for putting me off so long and bluntly explained that the reason he had done so was that he did not trust me... 'The anthropological perspective on evolution is no longer valid; it has been overthrown. And yet the science writers who insist on talking to me come drenched in an anthropological perspective, and there is really no point in talking to them... It is paralytic. It prevents you from asking certain questions, and it forces you to ask others. The whole discipline invites you not to investigate.'

...A few months before my visit, Wilson had announced at the annual meeting of the American Association for the Advancement of Science... that the Neandertals were replaced because they could not speak... suggesting that a particular gene for language might have been carried in the mitochondria themselves. Since invading males would have been more likely to mate with resident females than the other way around, the offspring of sexual contact between the two groups would be 'linguistically deaf-mute,' like their Neandertal mothers. Thus disadvantaged, these 'village idiots' would face the same fate as the mothers: extinction. Only the language-endowed African lineage would continue. The language gene idea, and especially the unfortunate term 'village idiots,' elicited hoots of derision from the anti-Eve camp, and gave no joy to Wilson's colleagues." [pp 119-121]

Sounds like global warming,climate change, obamanomics...
That is why I said I would wait for peer review.
