Quadrupedalism is a form of locomotion where an animal moves on all four limbs.

It's a common way for many animals, including mammals and reptiles, to get around.
Examples include cats, dogs, and horses.
While humans typically walk on two legs (bipedalism), we also exhibit quadrupedal movement, such as crawling as infants or in certain physical therapy exercises.
Here's a more detailed look:
Definition:
Quadrupedalism literally means "four feet" and refers to the use of all four limbs for walking, running, or other forms of movement.
Prevalence:
Many, if not most, terrestrial animals are quadrupedal.
Types of Quadrupedalism:
Different animals utilize various forms of quadrupedalism.
Some examples include:
- Digitigrade: Walking on toes (e.g., dogs, cats).
- Plantigrade: Walking on the soles of the feet (e.g., bears).
- Knuckle-walking: Walking on the knuckles of the hands (e.g., gorillas, chimpanzees).
Quadrupedalism in Humans:
While humans are primarily bipedal, we also experience periods of quadrupedal movement, such as crawling as infants and in certain therapeutic exercises.
Benefits:
Quadrupedal movement can offer benefits like improved coordination, balance, and full-body strength and conditioning, according to BrickHouse Nutrition.
Evolutionary Context:
Bipedalism in humans evolved from a quadrupedal ancestor, and understanding quadrupedal mechanics helps us understand the evolution of human locomotion.

People also ask
What is an example of quadrupedalism?
Quadrupedalism is sometimes referred to as being "on all fours", and is observed in crawling, especially by infants. In the 20th century quadrupedal movement was popularized as a form of physical exercise by Georges Hebert. Kenichi Ito is a Japanese man famous for speed running on four limbs in competitions.
What are the advantages of quadrupedalism?
Quadrupedalism provides enhanced stability on uneven terrain, which is beneficial for animals that live in complex environments. Many quadrupedal mammals have evolved specific limb structures that allow for efficient walking or running on all fours.
Are humans considered quadrupeds?
The quadrupeds include almost all the mammals. (Among the exceptions are whales, bats, and humans.) The Greek equivalent of this Latin word is tetrapod. However, the two are not identical, since the tetrapod classification includes bipeds such as birds, in which two of the limbs are no longer used for walking.
Here we compare the kinematics, kinetics, and energetics of bipedal and quadrupedal walking and running in a sample of five captive chimpanzees.
