>>43204146Digimon's evolution philosophy isn't like Pokemon's. Pokemon are animals that get bigger and stronger as they fight, Digimon is the advancement of data, learning and becoming more and more "perfect". So it mirrors actual evolution as we view it.
They start as stupid little single celled blobs, become simple animals, then apex predators and monsters, evolve into humanoids to mirror our idea of what a more advanced being is, then eventually surpass humanity through technology and become mechs and cyborgs, and sometimes straight-up gods and demons as the ultimate beings.
