Question

Quizplus · Accepted Answer

Studies have shown that Australopithecus afarensis had a slower rate of maturation than chimpanzees, indicating a longer period of developmental dependence on parents or caregivers.

Answer: B
 While Australopithecus afarensis brains were larger than those of chimpanzees, they were not three to four times bigger. However, they did show evidence of increased brain development and complexity compared to earlier hominins.

Answer: C
 There is currently no evidence to suggest that Australopithecus afarensis made or used stone tools.

Answer: D
 Fossil evidence suggests that Australopithecus afarensis likely lived in East Africa, specifically in the region of modern-day Ethiopia and Tanzania. There is no evidence to suggest they lived throughout West, Central, or South Africa.
