摘要: The sequencing of ancient DNA from archaic humans-Neanderthals and Denisovans-has revealed that modern humans interbred at least twice during the Pleistocene. field human paleogenomics has now turned its attention towards understanding nature this genetic legacy in gene pool present-day humans. What exactly did obtain interbreeding with Neanderthals Denisovans? Was introgressed material beneficial, neutral or maladaptive? Can differences phenotypes among populations be explained by introgression? These questions are prime importance for our recent evolution, but will require careful computational modeling extensive functional assays before they can answered full. Here, we review literature characterizing likely biological consequences their carriers. We focus particularly on haplotypes were beneficial to as expanded across globe, ways understand how harboring these evolved over time.
