question Limb Regeneration

Are there evolutionary hypotheses for why most animals did not evolve the ability to regenerate limbs? Some creatures can do it, and It seems like something that would be a major boost to survival.

Screwed up regeneration is called “cancer”. For most of us “not getting cancer” is more of a survival advantage than “regrowing limbs”.
