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 first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes. Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [ 11 ]
Homo sapiens emerged in Africa around 300,000 years ago [d] from the species Homo heidelbergensis. [e] [20] Humans continued to develop over the succeeding millennia, and by 100,000 years ago, were using jewelry and ocher to adorn the body. [21] By 50,000 years ago, they buried their dead, used projectile weapons, and engaged in seafaring. [22]
Modern humans, 200,000 to 300,000 years ago, were really adaptable, spanning from the Arctic tundra to the Sahara desert. Other things are still unknown about Homo erectus , like if they had a ...
The Neanderthal DNA found in modern human genomes has long raised questions about ancient interbreeding. New studies offer a timeline of when that occurred and when ancient humans left Africa.
Paleontologists are revealing early humans actually co-existed with a human-like species some 300,00 years ago. The cousin of homo sapiens, called homo naledi, was discovered in 2013 in a cave ...
Along with three perforated giant sloth bones found in Brazil that archaeologists believe humans used as pendants 25,000 to 27,000 years ago, the butchered armadillo bones suggest that humans were ...
Using the percent distance from human–chimpanzee last common ancestor, Denisovans/Neanderthals split from modern humans about 804,000 years ago, and from each other 640,000 years ago. [25] Using a mutation rate of 1 × 10 −9 or 0.5 × 10 −9 per base pair (bp) per year, the Neanderthal/Denisovan split occurred around either 236–190,000 ...
