Around 60,000 years ago, during the middle of an ice age, it was extremely cold in the far north, but ice sheets sucked up much of the moisture in Africa, making the continent even drier and droughts much more common. The result was a genetic bottleneck, pushing Homo sapiens to the brink of extinction, and a mass exodus from Africa.
According to multiple researchers, archaeological finds in New Mexico’s White Sands National Park date human activity in the area to between 21,000 and 23,000 years ago. Lowery now believes ...
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
Modern humans then repopulated Europe from the east after the eruption and the ice age that took place from 38,000 to 36,000 BCE. [104] A mitochondrial DNA sequence of two Cro-Magnons from the Paglicci Cave in Italy, dated to 23,000 and 24,000 years old (Paglicci 52 and 12), identified the mtDNA as Haplogroup N, typical of the latter group.

The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
Human history or world 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. They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of
Human activity through land use changes already by the Mesolithic had major ecological impacts; [38] it was an important influence on Holocene climatic changes, and is believed to be why the Holocene is an atypical interglacial that has not experienced significant cooling over its course. [39]
