Detailed explanation-1: -Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped /ˈbaɪpɛd/, meaning ‘two feet’ (from Latin bis ‘double’ and pes ‘foot’).

Detailed explanation-2: -Bipedalism (the ability to walk on two legs)

Detailed explanation-3: -bipedalism, a major type of locomotion, involving movement on two feet.

Detailed explanation-4: -But almost all the theories suggest that bipedalism is an adaptation to getting around on land. It’s clear that early bipeds evolved when savanna grasslands became increasingly common as forests retreated 4-8 million years ago. Walking on two legs made it easier to forage and travel on the ground.

Detailed explanation-5: -Humans, birds and (occasionally) apes walk bipedally. Humans, birds, many lizards and (at their highest speeds) cockroaches run bipedally. Kangaroos, some rodents and many birds hop bipedally, and jerboas and crows use a skipping gait.
