Archaic admixture in human history.
Modern humans evolved in Southern or Eastern Africa, and spread from there across the rest of the world. As they expanded across Africa and Eurasia, they encountered other hominin groups. The extent to which modern and 'archaic' human groups interbred is an area of active research, and while we know that modern humans interbred with Neanderthals and Denisovans, there is not yet agreement on how...
متن کاملPaleogenomics of Archaic Hominins
In order to understand the genetic basis for the evolutionary success of modern humans, it is necessary to compare their genetic makeup to that of closely related species. Unfortunately, our closest living relatives, the chimpanzees, are evolutionarily quite distant. With the advent of ancient DNA study and more recently paleogenomics - the study of the genomes of ancient organisms - it has bec...
متن کاملThe Archaic Maternal Superego
It is possible to argue that the concept is somehow in a latent state, under other names, in works that concern its clinical and theoretical area of interest or related matters. The sense in which I employ the term here is to designate a set of problems which are both clinical and theoretical, not the name for a supposed metapsychological agency whose theoretical necessity would be questionable...
متن کاملArchaic human ancestry in East Asia.
Recent studies of ancient genomes have suggested that gene flow from archaic hominin groups to the ancestors of modern humans occurred on two separate occasions during the modern human expansion out of Africa. At the same time, decreasing levels of human genetic diversity have been found at increasing distance from Africa as a consequence of human expansion out of Africa. We analyzed the signal...
متن کاملArchaic Adaptive Introgression in TBX15/WARS2
A recent study conducted the first genome-wide scan for selection in Inuit from Greenland using single nucleotide polymorphism chip data. Here, we report that selection in the region with the second most extreme signal of positive selection in Greenlandic Inuit favored a deeply divergent haplotype that is closely related to the sequence in the Denisovan genome, and was likely introgressed from ...
