This initial migration was followed by other archaic humans including H. heidelbergensis, which lived around ...
The first wave of modern humans in Europe (Initial Upper Paleolithic) left no genetic legacy to modern Europeans; [1] however, from 37,000 years ago a second wave succeeded in forming a single founder population, from which all subsequent Cro-Magnons descended and which contributes ancestry to present-day Europeans. [2][3] Cro-Magnons produced ...

Human history. Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers.

[2] Its specimens are among the first recognizable members of the genus Homo. Several human species, such as H. heidelbergensis and H. antecessor, appear to have ...
Experts estimate that modern humans first appeared between 42,653 and 42,269 years ago. Therefore, the authors conclude this suggests the two species of humans co-existed in these regions for ...
