The statement Homo erectus is preceded by Homo habilis is correct. Both evolved in pleistocene period. Homo habilis is the first hominid tool maker, It lived in early pleistocene about 1.75−2 million years ago. Homo erectus evolved after Homo habilis. According to another view, the australopithecines by the end of early pleistocene were widely dispersed in numerous small populations which occupied different habitats. Some populations developed in the direction of Homo habilis and some towards Homo erectus. A few might have become extinct.
