Hominini: The latest common ancestor of humans and chimpanzees is estimated to have lived between roughly 10 to 5 million years ago. Both chimpanzees and humans have a larynx that repositions during the first two years of life to a spot between the pharynx and the lungs, indicating that the common ancestors have this feature, a precondition for ...
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.

[112] [113] 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 modern humans (H. sapiens), representative of the earliest modern humans, and suggested that modern humans arose between 260,000 and 350,000 years ago through a merging of ...
6000 BC: Evidence of habitation at the current site of Aleppo dates to about c. 8,000 years ago, although excavations at Tell Qaramel, 25 kilometres (16 mi) north of the city show the area was inhabited about 13,000 years ago, [124] Carbon-14 dating at Tell Ramad, on the outskirts of Damascus, suggests that the site may have been occupied since ...
Archaeologists at Umm Jirsan recently found animal bones dating from 400 years to more than 4,000 years ago, and human remains ranging from 150 years to about 6,000 years ago.
A 2012 study led by Augustin Kong suggests that the number of de novo (new) mutations increases by about two per year of delayed reproduction by the father and that the total number of paternal mutations doubles every 16.5 years. [96] For a long time, medicine has reduced the fatality of genetic defects and contagious diseases, allowing more ...
A researcher claims to have found evidence of humans in Chesapeake Bay over 22,000 years ago. The assertion is yet another recent announcement claiming to push the arrival of humans in North ...
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.They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
