Early humans were social and initially scavenged, before becoming active hunters. The need to communicate and hunt prey efficiently in a new, fluctuating environment (where the locations of resources need to be memorized and told) may have driven the expansion of the brain from 2 to 0.8 Ma. Evolution of dark skin at about 1.2 Ma. [39]
With only a handful of species surviving today, the Nautiloids flourished during the early Paleozoic era, from the Late Cambrian, where they constituted the main predatory animals. [71] Haikouichthys, a jawless fish, is popularized as one of the earliest fishes and probably a basal chordate or a basal craniate. [72]
[142] [143] [144] [53] Fossilized skulls shows the brain size in early humans fell within the range of modern humans 300,000 years ago, but only got its present-day brain shape between 100,000 and 35,000 years ago. [145] The size and shape of the skull changed over time. The leftmost, and largest, is a replica of a modern human skull.
The early modern human vocal apparatus is generally thought to have been the same as that in present-day humans, as the present-day variation of the FOXP2 gene associated with the neurological prerequisites for speech and language ability seems to have evolved within the last 100,000 years, [124] and the modern human hyoid bone (which supports ...
Early modern human expansion in sub-Saharan Africa appears to have contributed to the end of late Acheulean industries at about 130,000 years ago, although very late coexistence of archaic and early modern humans, until as late as 12,000 years ago, has been argued for West Africa in particular.

Early humans navigated along river channels while on their way to Eurasia, it’s been claimed Scientific breakthrough confirms how early man left Africa 84,000 years ago Skip to main content
The migration of anatomically modern humans out of Africa took place in multiple waves beginning 194,000–177,000 years ago. [28] [f] The dominant view among scholars is that the early waves of migration died out and all modern non-Africans are descended from a single group that left Africa 70,000–50,000 years ago.
Homo (from Latin homō ' human ') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
