Through years of debate, most of the scientists and anthropologists are agreed that the early human first evolved in (B) Africa.
In Africa the first pre-historic man, Australopithecus’s baby skull fossil was discovered by Prof. Raymond Dart which dated 5 million years ago. The baby fossil was named as Australopithecus africanus (African ape man or Tuang baby).
Before Australopithecus there is only existence of ape like fossils which are not considered as early humans.
