The Origins Of Our Species Essays -- essays research papers

The latest discovery of a fossil skull in Kenya, more than than three billion years old, once again demonstrates the decomposable ontogeny of compassionate racekind. The following article examines the leaven and sees how it fits into the ideas of human origin theorise by Frederick Engels more than 100 years ago."There is a immenseness in this view of life, with its several powers, having been originally breathed into a hardly a(prenominal) mildews or into one and that, whilst this horizontalt has gone cycling on harmonize to the dictated law of gravity, from so simple a beginning perennial forms about beautiful and virtually wonderful have been, and be being, evolved." (Charles Darwin, The creation of the Species, pp. 459-60, Penguin 1985.)The latest discoveries in paleontology once again reveal the profuse and interlocking evolution of the human species. In March, the magazine Nature reported on a in the buff fossil find in Kenya of a 3.5 million year- old skull. Originally, it was public opinion that the human linkage had been traced back to an ancestral genus called the Australopithecines (the "Southern impersonator"), the most famous remains being Lucy, observe by D.C. Johanson. These proto-humans roamed the savannahs and breaking vale of Africa more than 3 million years ago, and are immediate to moderne humans than apes. However, new evidence suggests that the Australopithecus family was not the only when hominid species to have existed at this time.Nature describes a new species - Kenanthropus platyops - with a lots planeter manifestation than any Australopithecine. "Kenyanthropus shows persuasively that at least deuce beginnings existed as far back as 3.5m years," said Meave Leakey of the Kenya national museum. It is establish that the evolutionary tree is far bushier that at first appeared. While the human lineage split from that of the African apes some 5-10 million years ago, this new evidence s uggests possible new lines from which humans evolved. It shows a far great diversification of human evolution prior to the emergence of the Homo genus.The newly discovered skull has a small ear hole, like those of chimpanzees. However, it shares other features of earliest hominids, much(prenominal) as a small mastermind. But there are other striking differences, including tall cheekbones, small teeth and a flat plane beneath its nose bone, giving it a flat face appearance.

Gould has recognized Engels contribution, describing his essay on human origins as "a brilliant expose." However, notes Gould, it "had no visible impact on westward science." (Ever Since Darwin, p.210)" alone merit for the swift advance of civilization was ascribed to the mind, to the development and natural process of the brain", wrote Engels. "Men became accustomed to explain their actions from their thoughts, instead of from their needs... And so there arose in the course of time that idealistic outlook on the world, has dominated mens minds. It still rules them to such a degree that even the most bourgeois natural scientists of the Darwinian school are still unable to form any clear idea of the origin of man, because under that ideological model they do not recognize the part that has been played therein by labour."The latest discoveries in this field of human origins are a good word to Engels thought and contribution, not least the discovery of Kenanthropus platyops. It is a hitch of the rule of dialectical materialism, the only consistent scientific outlook of the world. The Origins Of Our Species Essays -- essays seek papers The latest discovery of a fossil skull in Kenya, more than three million years old, once again demonstrates the complex evolution of humankind. The following a rticle examines the evidence and sees how it fits into the ideas of human origin formulated by Frederick Engels more than 100 years ago."There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." (Charles Darwin, The Origin of the Species, pp. 459-60, Penguin 1985.)The latest discoveries in paleontology once again reveal the rich and complex evolution of the human species. In March, the magazine Nature reported on a new fossil find in Kenya of a 3.5 million year-old skull. Originally, it was thought that the human linkage had been traced back to an ancestral genus called the Australopithecines (the "Southern Ape"), the most famous remains being Lucy, discovered by D.C. Johanson. These proto-humans roamed the savannahs and Rift Valley of Africa more than 3 million years ago, and are closer to modern humans than apes. However, new evidence suggests that the Australopithecus family was not the only hominid species to have existed at this time.Nature describes a new species - Kenanthropus platyops - with a much fondle face than any Australopithecine. "Kenyanthropus shows persuasively that at least two lineages existed as far back as 3.5m years," said Meave Leakey of the Kenya national museum.
