Human Evolution
Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens, or human beings. Humans evolved from apes because of their similarities. Humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten different types families. Creationists believe that humans were always humans.Humans are classified in the mammalian family Primates. In this arrangement, humans, along with our extinct close ancestors, and our nearest living relatives, the African apes, are sometimes placed together in the family Hominidae because of genetic similarities. Two-legged walking seems to be one of the earliest of the major hominine characteristics to have evolved. In the course of human evolution the size of the brain has more than tripled. The increase in brain size may be related to changes in hominine behavior (See figure 3). The third major trend in hominine development is the gradual decrease in the size of the face and teeth.According to the Microsoft Encarta '98, the fossil evidence for direct ancestors of
5 million and 3 million years ago, A. Creationists say that human ancestors were not apes. habilis is the earliest known member of the genus Homo. habilis resembled modern humans with its limbs and small body size relative to its height. In details of their teeth, jaws, and brain size, however, they modify enough among themselves to explain division into five species: Australopithecus anamensis, A. habilis had a larger brain than australopithecines. Between 7 and 20 million years ago, primitive apelike animals were widely distributed on the African and, later, on the Eurasian continents. Homo erectus had a larger brain than earlier hominines. The robust australopithecines represent a specialized adaptation because their principal difference from other australopithecines lies in the large size of their chewing teeth, jaws, and jaw muscles. boisei, found only in eastern Africa. The creationist theory is only written and the evolutionary theory is actual living proof that humans did evolve from apes and why the environmental adaptations have made humans the dominant creatures on earth. habilis was taller than australopithecines, but shorter than Homo ere! ctus. africanus possessed a brain similar to that of its ancestor.
