By interbreeding with these archaic humans, we modern humans gained these advantageous adaptations.»
«What has emerged from our study as well as from other work on introgression is that interbreeding with archaic humans does indeed have functional implications for modern humans, and that the most obvious consequences have been in shaping our adaptation to our environment — improving how we resist pathogens and metabolize novel foods,» Kelso says.
Not exact matches
«Archaic human admixture with modern Ho.mo sapiens occurred at least twice in history: with Neanderthals, and with the population to which the Denisova ho.minin belonged.
Intermixing does not surprise paleoanthropologists who have long argued on the basis of fossils that archaic humans, such as the Neandertals in Eurasia and Homo erectus in East Asia, mated with early moderns and can be counted among our ancestors — the so - called multiregional evolution theory of modern human origins.
Pääbo, for his part, says that now that his team has shown that early modern humans interbred with one archaic group, he thinks other archaic humans might have passed along genes to us through interbreeding.
Still, additional genetic analyses have typically led researchers to conclude that Homo sapiens arose in Africa and replaced the archaic humans it encountered as it spread out from its birthplace without mingling with them.
That in turn could help determine when humans interbred with archaic hominids on other continents — such as Neandertals in Europe and Denisovans in Asia — whose genes linger in the DNA of some modern people (SN: 6/13/15, p. 11).
«There are certain classes of genes that modern humans inherited from the archaic humans with whom they interbred, which may have helped the modern humans to adapt to the new environments in which they arrived,» says senior author David Reich, a geneticist at Harvard Medical School and the Broad Institute.
«It opens up our ability to ask questions about how Middle Pleistocene hominins lived in this region and it might be a key to understanding the nature of interbreeding and population dispersals across Eurasia with modern humans and archaic populations such as Neanderthals.»
To answer that question, Collins and his team compared the chemical composition of the collagen in the fragments with the collagen produced by modern and archaic humans.
It also means that modern humans were potentially meeting and interacting during a longer period of time with other archaic human groups, providing more opportunity for cultural and biological exchanges.»
Importantly, this study indicated that LB1 not only differed from individuals with Down syndrome, but was more clearly aligned with more archaic human species.
When they did finally begin to disperse across the globe, according to this model, they replaced the archaic human species they encountered along the way, including the Neandertals, without interbreeding with them.

Published this week in Nature, the findings also hint at when modern humans interacted with other archaic humans.

Here we report newly discovered human fossils from Jebel Irhoud, Morocco, and interpret the affinities of the hominins from this site with other archaic and recent human groups.
No one knows when or how these humans disappeared but, according to Professor Paabo, it is very likely something to do with modern people because all the «archaic» humans, like Denisovans and Neanderthals disappeared sometime after Homo sapiens sapiens appeared on the scene.
Analysis of an archaic genome sequence indicated that the risk haplotype introgressed into modern humans via admixture with Neanderthals.
But ancient - DNA sequencing is beginning to shed some light on the issue.11 For example, by comparing a human HAR sequence with the HAR sequence of an archaic hominin, researchers can estimate if the HAR mutated before, after, or during the time period of our common ancestor.12 This approach has revealed that the rate at which HAR mutations emerged was slightly higher before we split from Neanderthals and Denisovans.3, 13 As a result, most HAR mutations are millions of years old and shared with these extinct hominins (but not with chimpanzees).
Homo naledi was likely there too, along with possibly still other archaic human species.
Feb. 11, 2016 — The first study that directly compares Neanderthal DNA in the genomes of a significant population of adults of European ancestry with their clinical records confirms that this archaic genetic legacy has a subtle but significant impact on modern human biology.
More specifically the scientists provide the first genetic evidence of a scenario in which early modern humans left the African continent and mixed with archaic (now - extinct) members of the human family prior to the migration «out of Africa» of the ancestors of present - day non-Africans, less than 65,000 years ago.
