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.
The Dmanisi skull, also known as Skull 5 or D4500, is one of five skulls discovered in Dmanisi, Georgia and classified as early Homo erectus.Described in a publication in October 2013, it is estimated to be about 1.8 million years old and is the most complete skull of a Pleistocene Homo species, [1] [2] and the first complete adult hominin skull of that degree of antiquity.
The researchers believe Homo erectus became isolated on the island around 1 million years ago and underwent a dramatic reduction in body size during a period of around 300,000 years. Such a ...
Homo erectus was the first ancient human to migrate out of Africa about 1.9 million years ago. Although Homo erectus had a gait and body size similar to modern humans, researchers think the ...
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.
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 ...
About 350,000 years ago a genome of an "erectus-like" creature was injected into the Denisovan lineage. With the separation time of about 2 Ma ago and interbreeding that happened 350 ka ago, the two populations involved were more distantly related than any pair of human populations previously known to interbreed.
