What is Theory of Man's Evolution?

Answer 1

Human evolution is necessarily part of the overall evolution of species, since without evolution of species there could be no evolution of humans. On the other hand, from a religious perspective, evolution could be true for lesser species, but not humans. In fact this was a nineteenth century proposition, because its proponents believed that God created man in his image. This proposition no longer has significant support and those who deny the fact of human evolution seek to disprove evolution altogether.

Although we may not be able to say who first defined evolution as the means by which new species arise, we do know that early pioneers of evolution theories include Jean-Baptiste Pierre Antoine de Monet, Geoffroy Saint-Hilaire and Lamarck. Charles Darwin (1809-1892) was the first to recognise the role of natural selection in evolution. He defined the process by which evolution occurs as being natural selection, in his Theory of Evolution by Natural Selection.

If we look at the other primates, we can see that the great apes are similar in some ways to humans, and similar in other ways to monkeys. In fact, scientists are able to say that humans and chimpanzees evolved from a common ancestor some seven million years ago. Fossil evidence is inconclusive in proving this link, but it can be shown from DNA analysis of modern chimpanzees and humans.

Or species is known as Homo sapiens. Current theories say that we evolved from our immediate ancestors, Homo erectusin Africa some 200,000 years ago. However, recent finds of Homo erectus in Asia reopen the possibility that the evolution of Homo sapiens may have been to some extent multi-regional.

Neanderthal man was a close relation to modern humans, and occupied parts of Europe and western Asia from abour 220,000 years ago until perhaps 30,000 years ago, co-existing with modern humans for some of that time. They were at once believed to be a subspecies of Homo sapiens, but most scientists now believe that they were a distinct species. Scientists also dispute whether the Neanderthals may have interbred with modern humans, and whether any offspring would have been fertile.

The probable ancestor of Homo erectus is Homo habilis, an even more ancient human species that lived about 2 million to 1.5 million years ago in Africa.

Earlier species that may have been our ancestors, or were at least related to our ancestors include Australopithecus boisei. Australopithecus robustus, Australopithecus africanus, AustraIopithecus afarensis, Kenyanthropus platyops, Orrorin tugenensis, Ramapithecus and Sahelanthropus tchadensis. Sahelanthropus tchadensislived seven million years ago.

Answer 2

Humans are primates. Apes, monkeys, chimpanzees, etc. are also primates.

Skeletons of primates that lived millions of years ago show that the ancestors of humans have changed from rather short hunched and probably furry primates that lived in groups and used stone tools to Homo erectus to the modern human.

The theory is that all primates probably had a common ancestor but due to separation of groups, environmental factors and random genetic mutations, speciation occurred and different groups of primates became increasingly different from each other. Modern primates do not look like their distant ancestors after millions of years and each species of modern primates are different from each other. The great ape is different from lemurs and humans. Humans are unique in having the ability to excavate, document and study the remains of organisms that lived millions of years ago.

Just as birds had a common ancestor with dinosaurs as did, perhaps reptiles, humans had a common ancestor with other mammals.

Answer 3

The theory of human evolution proposes that humans and apes share a common ancestor and have evolved over millions of years through a process of natural selection. This theory is supported by a wealth of scientific evidence from fields such as Paleontology, genetics, and anthropology. Key figures in developing this theory include Charles Darwin and Alfred Russel Wallace.

the origin of Creationism is true of all...

Answer 5

Theories of man include the idea that evolution is actually responsible for biodiversity. Another theory of man is the idea that dinosaurs died due to a large asteroid hitting Earth.
