But they can also leap up to 26 ft and walk bipedally with arms raised for balance. Prehistoric ear bones could lead to evolutionary answers. They have long, curved and slender digits on hands and feet with shorter thumb which help them to grab onto branches easily when they brachiate.

Comparative anatomy is the study of the differences and similarities in structure between different organisms. The study suggests the canals are the ones which developed into true ears.
