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.
The site is called Abri de Cro-Magnon (Cro-Magnon rock shelter), now recognised as a UNESCO World Heritage Site. [37] Abri means "rock shelter" in French, [citation needed] cro means "hole" in Occitan, [38] and Magnon was the landowner. [39] The original human remains were brought to and preserved at the National Museum of Natural History in ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.

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 ...
In September 2019, scientists reported the computerized determination, based on 260 CT scans, of a virtual skull shape of the last common human ancestor to anatomically modern humans, representative of the earliest modern humans, and suggested that modern humans arose between 260,000 and 350,000 years ago through a merging of populations in ...
Although many effects upon life on Earth and human evolution from the increase in cosmic rays have been tentatively proposed, the effects are not considered to have been strong enough (further refuted by paleoecological evidence) to have significantly affected natural or human history.

It's like someone stumbled upon this spikey orb, dared to take a bite, and thought, "Yes, let's create a culinary sensation that smells like a blend of rotten onions and gym socks." Truly, the ...
