Evolution has gone in the direction of reducing the number of legs. Primitive animals like centipedes have a lot of legs, but most of the time they're on their belly.

The reason is that primitive ecological niches are crowded with organisms and they have a lot of competition, forcing them to save every calorie.

The more complex the ecological niche, the more advanced organisms can master it. In such a niche, there is less competition and therefore more food. Too much food makes the body more energetic. And he can afford the luxury of having fewer legs, but longer and more powerful. With a surplus of power, you can barely lie on your belly. You can even bounce around. Lots and lots of time.

Ask the questions that interest you, even if they seem silly, childish, strange, funny, embarrassing, uncomfortable, or abstruse.
