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.
[16] [17] The relative lightness of female compared to male skin in a given population may be due to the greater need for women to produce more vitamin D during lactation. [18] The sweat glands in humans could have evolved to spread from the hands and feet as the body hair changed, or the hair change could have occurred to facilitate sweating.
Reconstruction of a female H. erectus 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 ...
Homo erectus are the first of our relatives to have human-like body proportions. Kaplan was a co-author of the findings published Thursday in the journal Nature Communications Earth and Environment.
Yuanmou Man is known only from two upper first incisors presumed to have belonged to a male, and a partial tibia presumed to have belonged to a female. The female may have stood about 123.6–130.4 cm (4 ft 1 in – 4 ft 3 in) in life. These remains are anatomically quite similar to those contemporary early Homo in Africa, namely H. habilis and ...
There is some uncertainty as to the sex of the individual. The smaller size of the D2700 skull compared to skulls D2280 and D2282 suggests as well as its more slender feature suggest female sex, [1] but the very large size of huge upper canines and large crowns have been argued to support classification as male.

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 ...
Male and female specimens were distinguished by assuming males were more robust than females, though both males and females are exceptionally robust compared to other Asian H. erectus. The adult skulls average 202 mm × 152 mm (8.0 in × 6.0 in) in length times breadth, and are proportionally similar to that of the Peking Man but have a much ...
