Humans Evolution - Human Ancestry
Homo


Us humans (Homo sapiens) are the highly intelligent primates and become the most dominant species on Earth, There are few more family member of Hominidae (the great apes, or hominids) chimpanzees, gorillas, and orangutans are the main and current part of the family Hominidae.

Humans Evolution - Human Ancestry


Human evolution, the process by which human beings evolved on Earth from now-extinct primates.

Humans and the great apes (large apes) of Africa -- chimpanzees (including bonobos) and gorillas share a common ancestor that lived between 8 and 6 million years ago.

 

Human Ancestry

 

Also, humans and ancestors have always shared Earth with other apes, apelike primates, from the modern-day gorilla to the long-extinct Dryopithecus. 


That we and the extinct apelike hominins are related and that we and the apes, both living and extinct, are related is accepted by anthropologists and biologists everywhere.


Yet the exact nature of our evolutionary relationships has been the topic of debate and investigation since the famous British naturalist Charles Darwin published his great books On the Origin of Species (1859) and The Descent of Man (1871).


Darwin never claimed, as some of his Victorian fellows insisted he had, that “man was descended from the apes,” and modern scientists would view such a statement as a useless simplification just as they would dismiss any popular ideas that a certain extinct species is the “missing link” between humans and the apes. 


There is theoretically, however, a common ancestor that existed millions of years ago. This ancestral species does not constitute a “missing link” along a lineage but rather a node for divergence into separate families.


The human “family tree” may be properly defined as a “family bush,” within which it is impossible to connect a full chronological series of species, leading to Homo sapiens, that experts can agree upon.



 

 

Rise of Humans (Homo sapiens)


As early Homo sapiens separated, it faced varieties of old humans both in Africa and in Eurasia, Eurasia notably Homo neanderthalensis


Since 2010, proof for gene run between archaic and modern humans during the period of roughly 100,000 to 30,000 years ago has been discovered. 


This includes modern human admixture in Neanderthals, Neanderthal admixture in all modern humans outside Africa, Denisova hominin admixture in Melanesians as well as admixture from unnamed archaic humans to some Sub-Saharan African populations.


The "out of Africa" migration of Homo sapiens took place in at least two waves, the first around 130,000 to 100,000 years ago, the second (Southern Dispersal) around 70,000 to 50,000 years ago, resulting in the colonization of Australia around 65–50,000 years ago, This recent out of Africa migration derived from East African populations, which had become separated from populations migrating to Southern, Central and Western Africa at least 100,000 years earlier. 


Modern humans afterward spread globally, replacing archaic humans (either through competition or hybridization). They inhabited Eurasia and Oceania by 40,000 years ago, and the Americas at least 14,500 years ago.
