Wikipedia About Human Evolution

for: History of the world

Human evolution, or anthropogenesis, is the part of biological evolution concerning the emergence of Homo sapiens as a distinct species from other hominans, great apes and placental mammals. It is the subject of a broad scientific inquiry that seeks to understand and describe how this change occurred. The study of human evolution encompasses many scientific disciplines, most notably physical anthropology, linguistics and genetics.

The term "human", in the context of human evolution, refers to the genus Homo, but studies of human evolution usually include other hominins, such as the australopithecines. The Homo genus diverged from the australopithecines about 2 million years ago in Africa. Several typological species of Homo, now extinct, evolved. These include Homo erectus, which inhabited Asia, and Homo neanderthalensis, which inhabited Europe.

Archaic Homo sapiens evolved between 400,000 and 250,000 years ago. The dominant view among scientists is the recent African origin of modern humans (RAO) that H. sapiens evolved in Africa and spread across the globe, replacing populations of H. erectus and H. neanderthalensis. Scientists supporting the alternative hypothesis on the multiregional origin of modern humans (MTO) view modern humans as having evolved as a single, widespread population from existing Homo species, particularly H. erectus. The fossil evidence is insufficient to resolve this vigorous debate.

Starting with H. habilis, humans began using stone tools of increasing sophistication. About 50,000 years ago, human technology and culture began to change more rapidly.

History of paleoanthropology

By 1859, the morphological similarity of humans to certain great apes had been discussed and argued for some time, but the idea of the biological evolution of species in general was not legitimized until Charles Darwin published On the Origin of Species in November of that year. Darwin's first book on evolution did not address the specific question of human evolution: "Light will be thrown on the origin of man and his history", was all Darwin wrote on the subject. Nevertheless, the implications of evolutionary theory were clear to contemporary readers.

Debates between Thomas Huxley and Richard Owen focused on human evolution. Huxley convincingly illustrated many of the similarities and differences between humans and apes in his 1863 book Evidence as to Man's Place in Nature. By the time Darwin published his own book on the subject, The Descent of Man, it was already a well-known interpretation of his theory, and the interpretation which made the theory highly controversial. Even many of Darwin's original supporters (such as Alfred Russel Wallace and Charles Lyell) did not like the idea that human beings could have evolved their impressive mental capacities and moral sensibilities through natural selection.
