H. erectus, apparently the first human species to control fire, likely originated in Africa and dispersed quickly through Africa, Europe, and South and Southeast Asia starting about 1.9 million years ago. In modern populations, males are on average a mere 15% larger than females, while in Australopithecus, males could be up to 50% larger than females by some estimates. These specimens are described as having morphological traits that justify placing them in the family Hominidae while creating a new genus for the classification of each. C.
