    This is the evolution of evolution, from the earliest single-celled life to the present mammals.

    Biological states exist in the form of natural selection, with advance and retreat. The reason why cats and dogs move on all fours is related to their way of survival, mainly on land, in order to pursue prey and escape from predators, running on all fours has become their natural choice.

    The two-legged mammals are basically only humans, and that is also the evolution of human brains that can use tools.

    All animals have four legs! Including people! Later, when people evolved to walk upright, their forelimbs evolved into upper limbs, and they were no longer called legs, but arms, and if dogs or other animals also evolved to walk upright,!!

    We humans may not be as smart as them! Are we humans still the masters? It's possible to be dominated by them, hehe! ok。

    1. This is determined by the dog's physiological characteristics and living environment.

    2. The speed of a dog can generally reach 50 kilometers per hour, while the speed of ordinary people is less than 40 kilometers per hour. I believe that many people can name the reason why dogs run faster than humans, and one of the theories is that dogs have four legs and are physiologically more suitable for running than humans.
