Hominid Skull Evolution Sharmili Lakshmanan Bio 1107 Introduction: Human evolution is the process of change by which people originate from apelike ancestor. Behavior traits and scientific evidence show that people are originate from apelike ancestor. Humans first evolved in Africa, and much of human evolution occurred on that continent. The process of evolution involves a series of natural changes that cause species to arise, adapt to the environment, and become extinct. All African early hominids—small australopithecines as well as the very tall Homo erectus have absolute body breadths within the modern human tropical-subtropical range; variations in relative body linearity is due almost entirely to variations in stature (Ruff, 1991).All species have originated through the process of biological evolution. Scientists classify each species with a scientific name. For modern humans, they are classified as Homo sapiens. Physical and genetic similarities show that the modern human species, Homo sapiens, has a very close relationship with the apes. The one early hominid to show a significant departure from this adaptive pattern toward later hominids—cranially, dentally, and postcranially—is H. habilis from East Africa ( Pilbeam et gould , 1974). The early hominids heads were significantly different from modern human. Modern human has larger brain size than the early hominids. Early hominids had
