Some archaic sequences are on positive selection pressure, thus suggesting that the extinct hominins might have facilitated the adaptation of H sapiens to new environments. 2017-06-23 Släktet Homo sapiens är litet av ett mysterium. Forskarna har svårt att säga varifrån det egentligen utvecklades, men den troliga förfadern är Homo erectus. Det dök snabbt upp flera olika arter av Homo sapiens i Afrika, Asien och Europa. Ingen av dem verkar egentligen varit särskilt framgångsrik förrän neanderthalmänniskan dök upp. Dlouhodobým problémem bylo, kam neandertálce ve vývojovém stromu člověka řadit.
Those early humans lived in caves instead of in trees like their ancestors. If you met a Neanderthal, the first thing you might notice is that your hominin cousin was a bit shorter than your average human. Neanderthals were both shorter and thicker than we are, so while you might beat them on the basketball court, they could probably out-arm-wrestle you. One of the most commonly known of these other humans is the Neanderthal, Homo neanderthalensis, which went extinct around 40,000 years ago. Modern humans and Neanderthals share common ancestors but one didn't evolve from the other, though it's generally believed that Neanderthals and homo sapiens interbred from time to time. Homo sapiens skulls from around 30,000 years ago also had larger brains on average than people today.

El Hombre de Neandertal (Homo neanderthalensis) es una especie del género Homo que habitó Europa y partes de Asia occidental desde hace "Homo sapiens neandethalis" blir kladistiskt märkligt eftersom Homo inte var sapiens när släktet delades upp till det som kom att bli sapiens och neanderthalis. På detta område händer det rätt mycket just nu och vår kunskap om människans evolution har ökat våldsamt mycket de senaste decennierna så det är svårt att hänga med för en lekman som mig.

Neanderthals used to be classified as a subspecies of modern humans (Homo sapiens neanderthalensis). Now, they are usually classified as a separate human species (Homo neanderthalensis). Modern humans, homo sapien sapiens, cohabited the Earth with several other human species at one point in time. One of the most commonly known of these other humans is the Neanderthal, Homo neanderthalensis, which went extinct around 40,000 years ago.
Where: across Europe and southwest and central Asia. Appearance: large nose, strong double-arched brow ridge, relatively short and stocky bodies. Brain size: at least 1,200cm 3 to 1,750cm 3.

In Europe and Asia, Homo sapiens met archaic Homo neanderthalis and H denisova. The presence of 1-3% neanderthalis sequences in modern Homo ADN indicates admixtures between these groups. Some archaic sequences are on positive selection pressure, thus suggesting that the extinct hominins might have facilitated the adaptation of H sapiens to new environments. In my view, if Neanderthals and Homo sapiens remained separate long enough to evolve such distinctive skull shapes, pelvises, and ear bones, they can be regarded as different species, interbreeding or not.
