The first member of the genus Homo to be hairless was Homo erectus, originating about 1.6 million years ago. [6] The dissipation of body heat remains the most widely accepted evolutionary explanation for the loss of body hair in early members of the genus Homo, the surviving member of which is modern humans.
The extant Homo heidelbergensis (cladistically granting Homo sapiens), which was originally African, emerged within the Asian Homo erectus. Contemporary groups appear to have been interbreeding, so any phylogeny like this only gives a coarse impression of the evolution of Homo , and extinct lineage may have partially continued in other groupings.
Java Man (Homo erectus erectus, formerly also Anthropopithecus erectus or Pithecanthropus erectus) is an early human fossil discovered in 1891 and 1892 on the island of Java (Indonesia). Estimated to be between 700,000 and 1,490,000 years old, it was, at the time of its discovery, the oldest hominid fossil ever found, and it remains the type ...
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 (from Latin homÅ '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.
This is a list of dates associated with the prehistoric peopling of the world (first known presence of Homo sapiens). The list is divided into four categories, Middle Paleolithic (before 50,000 years ago), Upper Paleolithic (50,000 to 12,500 years ago), Holocene (12,500 to 500 years ago) and Modern ( Age of Sail and modern exploration).
These sites attest that early Homo erectus have crossed the North African tracts, which are usually hot and dry. [4]: 2 There is little time between Homo erectus' apparent arrival in South Caucasus around 1.8 Ma, and its probable arrival in East and Southeast Asia.
They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by Homo erectus. This initial migration was followed by other archaic humans including H. heidelbergensis , which lived around 500,000 years ago and was the likely ancestor of Denisovans and Neanderthals as well as modern humans.
