[Pokemon] What is the common factor with all pokemon that allows them to be captured in pokeballs?

I mean if I throw a pokeballs at someone it will bounce off correct? Same if I do the same to a cat or dog. Is it something genetic? And how was it discovered?

Pokemon, when evolving turn into glowing energy and change their shape. Also, many pokemon can shoot and use some sort of energy blasts (or other supernatural forces).

It stands to reason that something about the physics of pokemons bodies is energy and pokeballs (and the apricorns that pokeballs are based on) can cause pokemon to revert to energy form.
