The chimpanzee–human divergence likely took place during around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.
The Boxgrove Palaeolithic site is an internationally important archaeological site north-east of Boxgrove in West Sussex with findings that date to the Lower Palaeolithic.The oldest human remains in Britain have been discovered on the site, fossils of Homo heidelbergensis dating to 500,000 years ago.

In 1868, Ernst Haeckel suggested early humans dispersed from the now-disproven hypothetical continent "Lemuria" (above). [3] [4]Despite what Charles Darwin had hypothesized in his 1871 Descent of Man, [b] many late-19th century evolutionary naturalists postulated that Asia (instead of Africa) was the birthplace of humankind as it is midway between all continents via land routes or short sea ...
A 2017 study of the ancient DNA of Tianyuan Man found that the individual is related to modern Asian and Native American populations. [113] A 2013 study found Neanderthal introgression of 18 genes within the chromosome 3p21.31 region (HYAL region) of East Asians. The introgressive haplotypes were positively selected in only East Asian ...
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.

The appearance of early hominins in Eurasia coincided with a reduction in the diversity of the continent's carnivore guild. It has been postulated that this was related to the Oldowan-Acheulean transition, as the development of Acheulean technology signifies a change in human ecology from a passive, scavenging role to that of more active predation.
The remains — buried in layers of soil in the collapsed cave — contained the genetic material of cave bears, hyenas and 13 bones of early humans who died some 45,000 years ago.
The brains of these early hominins were about the same size as that of a chimpanzee, and their main adaptation was bipedalism as an adaptation to terrestrial living. During the next million years, a process of encephalization began and, by the arrival (about 1.9 million years ago ) of H. erectus in the fossil record, cranial capacity had doubled.
