Question

Quizplus · Accepted Answer

The maturation rate of Australopithecus africanus was estimated by examining the relative eruption of teeth, as this provides a measure of age. The timing of tooth eruption is correlated with the rate of maturation in primates, with earlier eruption indicating a faster maturation rate.
