How can fossils teach scientists about the development of humans

The scientific hypothesis suggests that the first people of an anatomically modern type appeared in Africa. From here, various branches of the sapiens, including pygmies and bushmen, came from. The cradle of mankind refers to several complexes of caves located on an area of 474 square kilometers, where numerous hominins remains were found. In particular, bones of two species of Australopithecus, Sediba (Australopithecus sediba) and the most complete skeleton of African Australopithecus (Australopithecus africanus) were found here; fossils of massive Paranthropus (Paranthropus robustus) and Homo naledi also were found. The remains found in the Cradle of mankind confirm the hypotheses about the diversity of hominins and their evolutionary history. Some of these hypotheses link the evolution of humans and their ancestors to climatic conditions.
