Humans spontaneously switch from a walk to a run as speed increases. In humans, the preferred transition speed from walking to running typically occurs around 2.0 m/s (7.2 km/h; 4.5 mph), although slight differences have been shown based on testing methodology. [1] [2] [3] [4]
Quadrupedalism in an Iraqi family. In July 2005, in rural Turkey, scientists discovered five Turkish siblings who habitually walked on both their hands and feet. Unlike chimpanzees, which ambulate on their knuckles, the Ulas family walked on their palms, allowing them to preserve the dexterity of their fingers.
This can vary from odd-toed ungulates, such as horses, rhinos, and a few wild African ungulates, to even-toed ungulates, such as pigs, cows, deer, and goats. Mammals whose limbs have adapted to grab objects have what are called prehensile limbs. This term can be attributed to front limbs as well as tails for animals such as monkeys and some ...

In terrestrial vertebrates, digitigrade (/ ˈ d ɪ dʒ ɪ t ɪ ˌ ɡ r eɪ d /) [1] locomotion is walking or running on the toes (from the Latin digitus, 'finger', and gradior, 'walk').A digitigrade animal is one that stands or walks with its toes (phalanges) on the ground, and the rest of its foot lifted.
Capuchin monkeys are arboreal quadrupeds, but can locomote bipedally on the ground. [15] They use a spring-like walk that lacks an aerial phase. [15] While humans employ a pendulum-like gait which allows for the interchange of kinetic and potential energy, capuchins do not. [15] This means the energy costs of bipedalism in capuchins is very high.
