It is often thought thatHomo erectusis a good candidate to be the pre-Homo sapiensspecies, which would make him our evolutionary ancestor. Homo erectus is the most long-lived species of Homo, having survived for almost two million years. This dwelling's base measured about 3m 4m (9.8ft 13.1ft) on the exterior and 3m 2m (9.8ft 6.6ft) on the interior, and is considered to have been a firm surface hut, probably with a vaulted roof made of thick branches or thin poles, supported by a foundation of big rocks and earth, and likely functioned as a winter base camp. Although a formal definition of Homo erectus has not been established, the following characteristics are generally accepted. List Of Pharmaceutical Distributors In Dubai. [109], The earliest evidence of cave habitation is Wonderwerk Cave, South Africa, about 1.6 Mya, but evidence of cave use globally is sporadic until about 600 kya. H. erectus is associated with the Acheulean stone tool industry, and is postulated to have been the earliest human ancestor capable of using fire,[7] hunting and gathering in coordinated groups, caring for injured or sick group members, and possibly seafaring and art (though examples of art are controversial, and are otherwise rudimentary and few and far between).

Homo erectus is the scientific name of a species of the genus Homo, that is, a hominid, belonging to the evolutionary steps prior to humanity as we know it ( homo sapiens ). It also overlooks the fact that some modern populations have not seen any dramatic brain size increase relative to H. erectus with most of the increase occurring in European populations, which has the result of obscuring interpopulational variation. The short, short-limbed but heavy, muscular bodies of many Neandertal populations may indicate that they. "A Preliminary Comparison of Front and Back Squat Exercises", Research Quarterly for Exercise and Sport60, no. Homo, genus of the family Hominidae (order Primates) characterized by a relatively large cranial capacity, limb structure adapted to a habitual erect posture and a bipedal gait, well-developed and fully opposable thumbs, hands capable of power and precision grips, and the ability to make standardized precision tools, using one tool to make another.

Something that, in addition, could go hand in hand with the suspicion thatHomo erectuswas the first hominid toknow the fire and use it to cook his food. See Answer. [35] However, a 2015 study suggested that H. georgicus represents an earlier, more primitive species of Homo derived from an older dispersal of hominins from Africa, with H. ergaster/erectus possibly deriving from a later dispersal. Is Alexandra Lewis Married, What are some of the specific side effects of sedentism?A. [95] In 1979, American paleontologist Thomas Wynn stated that Acheulean technology required operational intelligence (foresight and planning), being markedly more complex than Oldowan technology which included lithics of unstandardized shape, cross-sections, and symmetry. He believed this fossil belonged to an ancient and 'upright' human and so coined the species name erectus. The extant Homo heidelbergensis (cladistically granting Homo sapiens), which was originally African, emerged within the Asian Homo erectus. [60] If H. erectus did not exhibit sexual dimorphism, then it is possible that they were the first in the human line to do so, though the fragmentary fossil record for earlier species makes this unclear. [129][123] However, scavenging animals and natural forces such as flooding can also inflict the same kind of damage to skulls,[123] and there is not enough evidence to suggest manhunting or cannibalism.

[112] Seafaring capability would show H. erectus had a great capacity for planning, likely months in advance of the trip. [83] It is debated if the H. e. pekinensis inhabitants of Zhoukoudian, Northern China, were capable of controlling fires as early as 770 kya to stay warm in what may have been a relatively cold climate. Homo erectus (/ h o m o r k t s /; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago. Changing sea levels have significantly affected the geography of South-east Asia and Australia and the m. Experts are tested by Chegg as specialists in their subject area. 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.
