Reacción a "Genomic analysis clarifies the chronology of Neanderthal-modern human admixture and its genetic impact on our species"

The main novelty of the study is to constrain the Neanderthal admixture episode very precisely to less than 50,000 years and to confirm that all modern humans today show the signs of this same episode.  

The most interesting consequences derive, however, from other collateral aspects; first, since humans in Asia and Australasia, who have signs of admixture with Denisovans, also have the common Neanderthal signal, that means that the same episode with Denisovans is still more recent. And second, since there are fossil remains attributed to modern humans in Asia (not only in China, but also in Laos and the Philippines) earlier than 50,000 years ago, these must correspond to an earlier departure out of Africa that, for reasons unknown to us, did not leave genomic traces in present-day humans. 

Surely the most interesting thing for the future would be to try to recover DNA from some of these early Asian Homo sapiens, to understand how they differed from those who left Africa a few tens of thousands of years later. Even if they did not reach the present day, it would be interesting to know if they also interbred with Neanderthals or Denisovans. The picture of this period in Asia is certainly complex and I think it needs to be explored as a whole.
