After all of the data, all observations concluded that the main development that occurred during evolution was the increase of brain size. [52] However, recent research has called into question the hypothesis of a threefold increase in brain size when comparing Homo sapiens with Australopithecus and chimpanzees. For example, in an article ...
However, modern Homo sapiens have a brain volume slightly smaller (1250 cm 3) than neanderthals, and the Flores hominids (Homo floresiensis), nicknamed hobbits, had a cranial capacity of about 380 cm 3 (considered small for a chimpanzee) about a third of that of Homo erectus.
This evolution continued in Homo erectus with 800–1,100 cm 3 (49–67 cu in), and reached a maximum in Neanderthals with 1,200–1,900 cm 3 (73–116 cu in), larger even than modern Homo sapiens. This brain increase manifested during postnatal brain growth, far exceeding that of other apes (heterochrony).
From early primates to hominids and finally to Homo sapiens, the brain gets progressively larger - with the exception of extinct Neanderthals whose brain size exceeded that of modern Homo sapiens. The volume of the human brain has increased as humans have evolved (see Homininae), starting from about 600 cm 3 in Homo habilis up to 1680 cm 3 in ...
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.
Simplified phylogeny of Homo sapiens for the last two million years. Genetic evidence suggests that a species dubbed Homo heidelbergensis is the last common ancestor of Neanderthals, Denisovans, and Homo sapiens. This common ancestor lived between 600,000 and 750,000 years ago, likely in either Europe or Africa.
Homo rhodesiensis ("Broken Hill Cranium"): dated to 324,000 to 274,000 years ago.. The category archaic human lacks a single, agreed definition. [11] According to one definition, Homo sapiens is a single species comprising several subspecies that include the archaics and modern humans.
Carl Linnaeus coined the name Homo sapiens. All modern humans are classified into the species Homo sapiens, coined by Carl Linnaeus in his 1735 work Systema Naturae. [9] The generic name Homo is a learned 18th-century derivation from Latin homÅ, which refers to humans of either sex. [10] [11] The word human can refer to all members of the Homo ...
