Neanderthal individuals from western europe that were older than 50,000 years and individuals from sites in western asia and the middle east showed a high degree of genetic variation, on par with.
Neanderthals emerged in europe around 400,000 years ago they began crossing paths 300,000 years later, as humans made their way into neanderthal territory eventually, these encounters became more and more common and, for between 10,000 and 15,000 years, the two species co-existed and interbred—2 percent of our dna comes from neanderthals. Inter-stratification of neanderthal and modern human remains has been suggested, but is disputed possible cause of extinction violence some authors have discussed the possibility that neanderthal extinction was either precipitated or hastened by violent conflict with homo sapiens. Professor chris stringer of the natural history museum also supports eiluned’s theory, and additionally uses archaeological evidence to support this theory for example, homo sapiens used needles to make clothing to keep them warmer, while the neanderthals did not.
Dr paola villa, from the university of colorado museum, and professor wil roebroeks, from leiden university, wrote in the online journal public library of science one argue that the differences between the two human sub-species are not enough on their own to account for the extinction of the neanderthals – research has found that the genomes. Neanderthals may have faced extinction long before modern humans emerged humans as a species in contrast, neanderthal individuals from unknown part of neanderthal history, quam said.
Neanderthals went extinct in europe around 40,000 years ago, roughly 5,000 to 10,000 years after first meeting homo sapiens there are several theories for their extinction around 40,000 years ago, the climate grew colder, transforming much of europe and asia into a vast, treeless steppe. An ecocultural model predicts neanderthal extinction through competition with modern humans, proceedings of the national academy of sciences (2016) doi: 101073/pnas1524861113 abstract archaeologists argue that the replacement of neanderthals by modern humans was driven by interspecific competition due to a difference in culture level. Video: neanderthals: did cro magnons, the ancestors of early humans, cause the neanderthal extinction what they found was a distinct set of denisovan ancestry among some modern east asians—particularly han chinese, chinese dai and japanese—ancestry not found in south asians or papuans. Neanderthals (homo neanderthalensis) were widespread across europe and western asia for a long time, starting about 400,000 years ago but things began to change when populations of homo sapiens (earlier members of our own species) migrated from africa to europe at about 45,000 years ago five thousand years later not a single neanderthal remained.
What drove neanderthals to extinction maybe us : 137: cosmos and culture anthropologist barbara j king reviews a new book that suggests domesticating the wolf gave early modern humans an extra edge in hunting that pushed neanderthals to extinction. Another hypothesis, with respect to the extinction of the neanderthals, is related to the drastic change in climatic conditions during the last ice age, when europe was semi-desert with sparse vegetation the result of this was the disappearance of many species of plants and animals, which formed a major portion of the food of the neanderthals.
Though it's a relative underdog among neanderthal-demise theories, genetic swamping is a well-known extinction cause among plant and animal species.
