Question

Whose skulls ‘A’, ‘B’, and ‘C’ are shown below? Which of the two are more similar to each other?

Answer 1

Because of its insufficient development, the skull of a young chimpanzee (B) resembles the skull of an adult human (A) more than the skull of an adult chimpanzee (C). Because both species share some anatomical traits in their early stages of development, several features observed in the skulls of infant chimpanzees and adult humans are similar. This likeness, which reflects the evolutionary ties between humans and chimpanzees, is ascribed to the young chimpanzee's cranium retaining certain rudimentary features.
