domestic honey bees (apis mellifera) have a bunch of DNA that doesnt align with many other animals, it just looks like a random string, I doubt it even codes for any protein

when did bees diverge from ants? nobody knows but 100 million years is as good guess as any

both are colonial insect

some ants have a stinger but its rare

bee is obviously better evolved as a flyer, ants are not great flyers even when winged
