Bunnies prevalence on EEA is uncertain, at best. There are few species so widely hunted as the bunny, but it might be the case that the cute ones were slightest less hunted and reproduced more. Or, we might have selected then for neoteny, as we do whenever we have a chance (dogs, cats, cows, donkey), it makes them more docile and easy to slaughter and enslave. We finding them cute would be then both a side effect of (1) evolutionary pressures for not wasting energy in building an excessively fine tuned cuteness-taste and (2) the fact the most easy way to select for easiness-to-slaughter-and-enslave is to select for baby-like faces. Evolution is a nasty, lazy, immoral mistress."Had Mother Nature been a real parent, she would have been in jail for child abuse and murder."
