Human Timeline: How Long Have Humans Existed?
The earliest modern human (Homo sapiens) fossil found was dated at 200,000 years old in Morocco, Africa.
But if you look at our genus (Homo), Homo Habilis arose 2.8 million years ago in Africa.
Hominins which includes human species and immediate ancestors emerged about 7 million years ago in Africa.
Finally, hominids which includes gorillas, orangutans, chimpanzees, bonobos and humans existed 11 to 16 million years ago.
So in the grand scheme of things, humans have existed for a miniscule portion of Earth’s history. Much less than 1%.
If you hold out your arm and clipped a fingernail, that’s less than the duration that humans have existed in Earth.
Homo Sapiens vs Hominins vs Hominids
‘Hominid’ (Hominidae family) have the broadest meaning referring to all Great Apes and their ancestors. Hominids were the early proto-humans who are believed to have stemmed from lesser apes such as modern gibbons.
Hominins are extinct or alive species that are more closely related to humans than chimpanzees. This includes genuses homo, australopithecus, ardipithecus and paranthropus. Humans are the only remaining living hominin.
Homo or “human being” emerged from the extinct Australopithecus genus. The first appearance of the Homo genus was in Eastern Africa as the “Homo Habilis” species. It stood about one meter tall with a larger brain and teeth than its australopithecine relatives.
Finally, Homo Sapiens made the first appearance on the family tree about 200,000 years ago in Africa with modern faces and larger brains. Neanderthals had an equally large brain, which existed about 300,000 years ago. There is no proof that modern-day humans are related to H. Heidelbergensis.
How Homo Sapiens Survived
Humans migrated and spread throughout the continents. Like an insurance policy, this helped prevent humans from extinction during cold spells.
But our distinct advantage was our enormous brains and ability to communicate. Homo sapiens were known for artistic talents in cave paintings and clay work.
They made hooks and spears to catch fish and invented the spear thrower. Thus, it made them better hunters because they could hunt from a distance.
About 160-40 thousands years ago, the “doubly wise man” were the recent form of modern humans “homo sapiens sapiens”. Eventually, modern humans invented more complex language, practiced agriculture and built cities.
