In the case of human evaluators of babies, not only our genetic proximity to the baby must be taken in consideration.
Human females pupils dilate (signal of attraction) when seeing a baby.
Human male pupils will vary, with the case being that childless man are more likely to get a shrinkage, while fathers mostly have dilated pupils.
Sometimes it pays not to detect something, evolutionarily speaking, some levels of egoism are tolerated and forgotten to keep future altruism, for instance. Females are pro-babies in general probably because it would be too costly to find other babies neutral, or ugly. The male scenario is a bit different.
Also, we see babies all the time, so we should beware of Contrast Effect bias in favor of the bunny.
Cuteness is not an universal trait, otherwise we would share this Vulture’s mum’s intuition.
