The genome of the offspring of a Neanderthal mother and a Denisovan father

Abstract

Neanderthals and Denisovans are extinct groups of hominins that separated from each other more than 390,000 years ago. Here we present the genome of 'Denisova 11', a bone fragment from Denisova Cave (Russia) and show that it comes from an individual who had a Neanderthal mother and a Denisovan father. The father, whose genome bears traces of Neanderthal ancestry, came from a population related to a later Denisovan found in the cave. The mother came from a population more closely related to Neanderthals who lived later in Europe than to an earlier Neanderthal found in Denisova Cave, suggesting that migrations of Neanderthals between eastern and western Eurasia occurred sometime after 120,000 years ago. The finding of a first-generation Neanderthal-Denisovan offspring among the small number of archaic specimens sequenced to date suggests that mixing between Late Pleistocene hominin groups was common when they met.

On the postglacial spread of human commensal Arabidopsis thaliana: journey to the East

“…While the higher heterozygosity may result from recent outcrossing events or DNA contamination, both samples have very low chloroplast heterozygosity compared with all other accessions (< 0.001), making DNA contamination with nonrelicts in the laboratory less likely. As the number of heterozygous sites in an individual reflects the number of SNPs between its two parents, we suspected that the high heterozygosity of SRR2204316 might result from the cross between two genetically divergent groups, similar to a recent study in ancient humans (Slon et al ., ).…”

Impact of Historic Migrations and Evolutionary Processes on Human Immunity

“…The historical exodus of mankind started almost 2 million years ago with the migration of Homo erectus from Africa through Eurasia. From this event on, relatively isolated human populations evolved separately on different continents, leading to the emergence of different human species, such as Neanderthals in Europe, the Denisovans in Asia, and, later, modern Homo sapiens in Africa [92,93]. H. sapiens first colonized large areas of the continent around 300 000 years ago [6], spread towards the Middle East at some point between 150 000 and 80 000 years ago, and migrated through Eurasia, reaching Australia within 20 000 years [94].…”

An amphibian species pushed out of Britain by a moving hybrid zone

“…Hypothetical larger dispersal and long‐distance dispersal would widen a hybrid zone and disturb the typically clinal character‐state transitions (Barton & Hewitt, ; Ibrahim, Nichols, & Hewitt, ). An erratic, large‐scale pattern appears to describe the spatial‐genetic interactions of the lineages of anatomically modern humans and for example, Neanderthals, with frequent interbreeding when hominin species' ranges overlapped (Petr, Pääbo, Kelso, & Vernot, ; Slon et al, ; Vernot & Akey, ). The inferred species transition that was labelled as “leaky replacement” (Pääbo, ; see also Gibbons, ), parallels that of a moving hybrid zone leaving a genetic footprint.…”
