Australopithecus africanus's maturation rate was determined by
A) the cranial suture closure.
B) the long bone suture closure.
C) relative tooth eruption.
D) relative nail growth.

Question

Quizplus · Accepted Answer

Relative tooth eruption is a reliable indicator of maturation rate in Australopithecus africanus as these hominins had a slower rate of dental development compared to modern humans. The first molars erupted at around 4-4.5 years of age, and the last molars erupted at around 14-16 years of age, indicating a prolonged period of growth and development. The other options (A, B, D) are not as reliable indicators of maturation rate in this species.
