The similarity in cost between bipedal and quadrupedal trials suggests that the adoption of bipedal walking would have had no effect on walking costs for early ape-like hominins. Over the last decade, there have been a number of important fossil discoveries in Africa of what may be very early transitional hominins, or proto-hominins. One of the first actions of locomotion that we'll ever undertake as humans is a crawling motion – moving on all four limbs across an even or uneven surface, usually around six months to 1 year old.

Proc Natl Acad Sci U S A. English. Limb work and joint work minimization reveal an energetic benefit to the elbows-back, knees-forward limb design in parasagittal quadrupeds. Here we compare the kinematics, kinetics, and energetics of bipedal and quadrupedal walking and running in a sample of five captive chimpanzees. So what do we think everyone, is this just a very unique, possibly mutated gorilla or is this another step in evolution taking it’s toll on this special ape? Quadrupedalism is a form of terrestrial locomotion where a tetrapod animal uses all four limbs to weightbear, walk and run.An animal or machine that usually maintains a four-legged posture and moves using all four limbs are said to be a quadruped (from Latin quattuor for "four", and pes for "foot").
