Stone tools found at the Shangchen site in China and dated to 2.12 million years ago are considered the earliest known evidence of hominins outside Africa, surpassing Dmanisi hominins found in Georgia by 300,000 years, although whether these hominins were an early species in the genus Homo or another hominin species is unknown.

Homo erectus (/ ˌ h oʊ m oʊ ə ˈ r ɛ k t ə s / lit. ' upright man ') is an extinct species of archaic human from the Pleistocene, spanning nearly 2 million years.It is the first human species to evolve a humanlike body plan and gait, to leave Africa and colonize Asia and Europe, and to wield fire.
[2] [3] Estimates on the number of Earth's current species range from 10 million to 14 million, [4] with about 1.2 million or 14% documented, the rest not yet described. [5] However, a 2016 report estimates an additional 1 trillion microbial species, with only 0.001% described. [6]
The Virgin Galactic 03 space trip included some fossilized remains of ancient human relatives Australopithecus sebida and Homo naledi.
A principal finding is that the X chromosomes of humans and chimpanzees appear to have diverged about 1.2 million years more recently than the other chromosomes. The research suggests: There were in fact two splits between the human and chimpanzee lineages, with the first being followed by interbreeding between the two populations and then a ...
There are ancient geological strata there, layers that date back millions and millions of years. I was walking on sediment 3.2 million years in age searching for the fossilized remains of various ...
Homo sapiens (red, Out of Africa II), with the numbers of years since they appeared before present. Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents. They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by Homo erectus.
By 3 million years ago the broad pattern of human dentition was in place with reduced canines and a jaw morphology implying heavier chewing. [1] Stone tools and butchered animal remains dating to 2.6 million years ago have been found together in Ethiopia.
