What is bipedal hopping?

Bipedal hopping is a specialized mode of terrestrial locomotion characterized by sustained saltatory motion in which the hindlimbs contact the ground simultaneously with no involvement of the forelimbs (Bartholomew and Caswell, 1951; Howell, 1932).

What is an example of a physiological adaptation?

Physiological adaptation is an internal body process to regulate and maintain homeostasis for an organism to survive in the environment in which it exists, examples include temperature regulation, release of toxins or poisons, releasing antifreeze proteins to avoid freezing in cold environments and the release of …

What was the adaptive advantage of bipedalism for early hominids?

The host of advantages bipedalism brought meant that all future hominid species would carry this trait. Bipedalism allowed hominids to free their arms completely, enabling them to make and use tools efficiently, stretch for fruit in trees and use their hands for social display and communication.

What are two specific examples of hominin skeletal adaptations for bipedalism?

Some early hominins appear to, for instance, have bowl-shaped pelvises (hip bones) and angled femurs suitable for bipedalism but also have retained an opposable hallux (big toe) or curved fingers and longer arms (for arboreal locomotion).
