Sentences with phrase «erectus ergaster»

Dmanisi team members, among others, contend that the Georgian fossils belong to a single early population of H. erectus or to a single sub-subspecies, Homo erectus ergaster georgicus.

Not exact matches

H. ergaster may be distinguished from H. erectus by its thinner skull bones and lack of an obvious sulcus.

The size of the Ileret footprints is consistent with stature and body mass estimates for Homo ergaster / erectus, and these prints are also morphologically distinct from the 3.75 - million - year - old footprints at Laetoli, Tanzania.

Until the discovery of the first jawbone at Dmanisi 25 years ago, researchers thought that the first hominins to leave Africa were classic H. erectus (also known as H. ergaster in Africa).

We learn in the February 27 issue of Science that a team working at Illeret, near Lake Turkana in Kenya, or many years the site of fossil finds, has uncovered two trails with footprints estimated to be 1.5 million years old and likely made by individuals assigned to Homo ergaster / erectus.

On the whole though, most researchers see too little difference between ergaster and erectus to form the basis of a species of the former, separated from the latter.

As a general rule of thumb, one can consider most attributed ergaster specimens to be early erectus geographically confined to Africa (however, this is not a hard and fast rule).

Also, more recent analyses by other researchers seem to indicate that even if ergaster specimens are considered as a different taxon than erectus, the erectus material is still closer to modern humans cladistically.

They tend to see ergaster as a direct ancestor of modern humans with erectus being an evolutionary dead - end.

Early members of our own genus, Homo erectus, and its near relative, Homo ergaster, arose in the same region about 2.5 million years ago.

98 The fauna associated with Australopithecine fossils indicate a wooded environment (Reed 1997, p. 318); their Paranthropus successors were sometimes found in wetland environments, but it is only the later Homo species (ergaster, erectus) that are found in extremely arid and open landscape.
