This maturity schedule in australopiths is consistent with ape-like estimates of age at death for the Nariokotome Homo erectus remains KMN-WTwhich are of similar postcranial immaturity to MH1. The small group of four female maxillary specimens has no association of size and wear.
For example, when male baboons disperse, they suffer a mortality rate at least three times as great as that of group-living males or females Was it because they were able to migrate to where their usual food sources were located?
The crowns of the teeth do not grow during adolescence or after sexual maturity, but the maxilla and mandible may grow substantially — just as the faces and jaws of gorillas and orangutans become somewhat larger during the development of adult males.
Some of them go on to develop large body size and flanges immediately upon reaching sexual maturation, others reach sexual maturation and are able to reproduce, but remain smaller and flangeless for many years.
Nature The teeth and jaw of Au. The findings suggest that humans may have distinctive and delayed post-cranial schedules from australopiths and H.
