According to a recent article on the evolution of humanity, the evolution of the human being is not very linear, according to Susan C. Anton. The Koobi Fora association has sponsored the excavation of African remains to determine their relationship to modern humans. The specific remains found display a human-like head with appropiate skull structre, yet no lower jaw. Therefore, the effect of ones ability to consume a variety of food is shown as a positive trait; this particular characteristic did not proliferate succesfully. Ms. Anton speculates that the remains display the final peice of re-affirming evidence that a variety of sub-species of Homo Erectus have lead to the modern species. Africa is also shown as a highly important base for the evolution of the modern human's early evoltuion, before the line of the early representatives of the Genus ventured further. COnclusively, the article, (because it was not written well,) alludes to the notion that these various groups of semi/primal humans branched, mated with other sub-sets, and became extinct.
This article speaks to various example of factors that lead to the development of a species. FOr exaple, natural selection is specifically displayed in the unfavorable nature of the jaw, because it is not visible within the modern. The concept of speciation is shown in a peculiar fashion, although there are noticeable sub-species of human, they did not survive along with the Homo Sapiens. it can be surmised that behavorial selection could also have been determinent to this development, as certain physical profiles could have been sexually favored.
About how long ago are these remains from?
