Indeed, it always a source of surprise to me that human babies will cry regardless of the situation, whereas the offspring of other animals seem to have an instinct to remain quiet while the mother is not about, or there's a perceived danger.

Unlike kittens and superior animals, ape babies are not meant to be abandoned at any point, under no circumstances. They are meant to be carried around by their mothers or substitute relatives, clinging to them, so their sudden whimsical needs can be catered to immediately, or else you run the risk of developing an insecure attachment relationship.

Google images for “monkey attached mother”.

Well if you come with an assumption we are like the other animals you are going to make an ass of someone.

Well not like ALL animals, since not all animals act the same way. I don't expect we are like fish, that (some?many?most?) are abandoned as eggs to make it on our own, or like sharks that have two wombs and the mama-shark keeps generating eggs to feed the two stronger babies (one in each womb).

I assume that those who "group" us based on similarities on the behavior and manner we raise our offspring must have use some logic to the process.
