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.
KNM ER 3733 [a] is a fossilized hominid cranium of the extinct hominid Homo ergaster, alternatively referred to as African Homo erectus.It was discovered in 1975 in Koobi Fora, Kenya, right next to Lake Turkana, in a survey led by Richard Leakey, by a field worker called Bernard Ngeneo.
Homo erectus derives from early Homo or late Australopithecus. Homo habilis , although significantly different of anatomy and physiology, is thought to be the ancestor of Homo ergaster , or African Homo erectus ; but it is also known to have coexisted with H. erectus for almost half a million years (until about 1.5 Ma).
"Homo erectus spread from Africa to western Asia, then east Asia and Indonesia. Its presence in Europe is uncertain, but it gave rise to Homo antecessor, found in Spain." "Homo heidelbergensis originated from Homo erectus in an unknown location and dispersed across Africa, southern Asia and southern Europe."
Homo neanderthalensis greatest extent (ochre) during Out of Africa and 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 ...
The technology demonstrates an increase in brain development and complexity in Homo erectus, as shown by the increased level of forethought and knowledge of material required for production of the tools. [13] Homo erectus are also associated with the first instances of "modern human living,, such as fire, "modern emotions", and art. [14]
KNM-ER 3883 is a significant fossil specimen of early African Homo erectus, dating to approximately 1.5–1.6 million years ago.This cranium, discovered in Kenya, has an endocranial volume exceeding 800 cc, which is substantially larger than earlier Homo species and suggests a notable increase in brain size.
Successive expansions of Homo erectus (yellow), Homo neanderthalensis (ochre) and Homo sapiens (red). Evidence was found in 2018, dating to about 320,000 years ago, at the Kenyan site of Olorgesailie , of the early emergence of modern behaviors including: long-distance trade networks (involving goods such as obsidian), the use of pigments, and ...
