Australopithecus came to the attention of the scientific world in 1924 when Raymond Dart, a South African anatomy professor, was given the fossil skull of a young child, found at Taung, Cape Province, South Africa. Although the teeth were shaped differently from those of the apes and resembled those of modern humans, the brain of the Taung child, even had it reached maturity, would have been no larger than that of a gorilla. Breccia is a type of rock composed of large angular fragments that have become cemented together. Unlike the cobbles in conglomerates, which have been rounded by transport, the angular fragments of breccias have been formed in place rather than by erosion and sedimentation. Cave Chamber beneath the surface of the earth or in the side of a hill, cliff, or mountain.
Caves vary in size and shape, and many have large openings to the surface.
Dolomite A magnesia-rich sedimentary rock resembling limestone. Evolution Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a progression that includes the most advanced animals and plants. Exactly how evolution occurs is still a matter of debate, but that it occurs is a scientific fact. Biologists agree that all living things arose through a long history of changes shaped by physical and chemical processes that are still taking place. It is plausible that all organisms can be traced back to the origin of LIFE from inanimate matter.
