Why do dog breeds look so different (compared to cats) — 2 Comments

  1. There seems to be more to it than that. Dogs have more genetic plasticity which allows them to be bred into more diverse forms. Cats don’t have such genetic plasticity and even with selective breeding they don’t deviate far from their natural size and conformation. This may be linked to lifestyle – cats are optimised for a solitary hunter role and being full of mutations would compromise that. Dogs operate as packs and this can accommodate animals that are better, or worse at various roles in the pack such as chasing, guarding, baby-sitting, herding, killing etc. Humans worked with genetic traits already present in wolves. Wolves were predisposed to being selectively bred and changed. Cats, not having a pack to fall back on, are predisposed to resist change.
