What is bipedalism?

Bipedalism is the ability to walk on two legs. It is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. Bipedalism is a key characteristic of humans and some other primates, as well as certain birds and dinosaurs.

Bipedalism refers to the ability of a species to walk or run on two legs, using their hind limbs for locomotion while their forelimbs are free for other tasks. It is a characteristic feature of humans but is also seen in various other animals, including birds, kangaroos, and ostriches.
