Homo erectus (meaning 'upright man') is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago,[2] and its specimens are among the first recognisable members of the genus Homo. H. erectus was the first human ancestor to spread throughout the Old World, having a distribution in Eurasia extending from the Iberian Peninsula to Java. African populations of H. erectus are likely to be the direct ancestors to several human species, such as H. heidelbergensis and H. antecessor, with the former generally considered to have been the direct ancestor to Neanderthals and Denisovans, and sometimes also modern humans.[3][4][5] Asian populations of H. erectus may be ancestral to H. floresiensis[6] and possibly to H. luzonensis.[7] As a chronospecies, the time of the disappearance of H. erectus is a matter of contention. There are also several proposed subspecies with varying levels of recognition. The last known record of morphologically recognisable H. erectus are the Solo Man specimens from Java, around 117–108,000 years ago.[1]H. erectus had a humanlike gait and body proportions, and was the first human species to have exhibited a flat face, prominent nose, and possibly sparse body hair coverage. Brain capacity varied widely depending on the population, ranging from 546–1,251 cc (33.3–76.3 cu in), and maximum brain size was likely achieved early on in life, suggesting a shorter childhood and lesser parental care than in modern humans. Size also ranged widely from 146–185 cm (4 ft 9 in–6 ft 1 in) in height and 40–68 kg (88–150 lb) in weight. H. erectus men and women may have been roughly the same size as each other (exhibit reduced sexual dimorphism) like modern humans, which could indicate monogamy in line with general trends exhibited in primates. Skin colour potentially varied with location.

Skin colour potentially varied with location.H. erectus is associated with the Acheulean stone tool industry, and is thought to have been the earliest human ancestor capable of using fire, hunting and gathering in coordinated groups, caring for injured or sick group members, seafaring, and possibly art-making. Sites generally show consumption of medium to large animals, such as bovines or elephants, and a high reliance on meat is associated with increasing brain size. Though groups were more social than ancestor species, it is unclear if H. erectus was anatomically capable of speech, though it is postulated they communicated using some proto-language.
