Bipedalism is a form of terrestrial locomotion where an animal moves by means of its two rear (or lower) 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').

2024年12月6日 · bipedalism, a major type of locomotion, involving movement on two feet. The order Primates possesses some degree of bipedal ability. All primates sit upright. Many stand upright without supporting their body weight by their arms, and some, especially the apes, actually walk upright for short periods.

2019年5月29日 · Bipedality, the ability to walk upright on two legs, is a hallmark of human evolution. Many primates can stand up and walk around for short periods of time, but only humans use this posture for their primary mode of locomotion.

2025年2月1日 · There are many theories that attempt to explain why humans are bipedal, but none is wholly satisfactory. Increased speed can be ruled out immediately because humans are not very fast runners. Because bipedalism leaves the hands free, some scientists, including Darwin, linked it to tool use, especially tools for defense and hunting —i.e., weapons.

Hartmut Witte and colleagues’ refreshing comparison, from an engineering perspective of robotic and human bipedalism, showed that the design features of human bipedality are set not only by our more recent common ancestry but also our most ancient affinities.

The meaning of BIPEDALITY is bipedalism.

2023年12月28日 · One of the most distinctive human traits is our ability to walk on two feet, known as bipedalism. But how did this unique form of locomotion come to be, and what does it say about our evolution? Let’s embark on a journey through time to uncover the anatomical and evidence-based insights into the evolution of bipedalism in humans.

Our bipedal body structure is unique amongst living apes. In fact, our ancestors started on the path to becoming human when they began walking on two legs. About seven million years ago, our early ancestors climbed trees and walked on four legs when on the ground.

2024年10月14日 · One difference that you might notice right away is how we walk. Humans walk on two legs, which we call bipedality. Our two-legged walking makes us unique. Other mammals, like your pet dog or cat, usually walk on all four legs, which we call quadrupedalism.

2024年10月27日 · Explore the evolutionary journey and anatomical changes that led to bipedalism in humans and extinct species. The ability to walk on two legs, known as bipedalism, is a defining characteristic of humans that sets us apart from most other mammals.
