As any women (or man watching this) who has tried to nurse a newborn baby can tell you, the nipple is not very intuitive. It is a lot of effort to teach a baby to use a nipple correctly. Few know how to teach this skill anymore and so a lot of mothers spend a lot of money on bottles/formula. (formula is fine for those who can't make nursing work in their life, but where it would work many use formula anyway because it is so hard to learn)

You are right. Millions of years of evolution, thousands of mammal species, but none of them really could feed properly until Homo Sapiens came around with a proper "nursing 101" class and invented baby formula.

Life would be impossible without it.

(I do my best to avoid snarky responses, but do you realize how your comment amounts to pointless pontification?)

Evolution works for survival, at some point it 'decided' that since humans can teach other we don't need the instinct anymore. If you study at all you will find plenty of similar things across many different species.

Where is the study that teaches you to take a hint and stop with the midwit pontification?

What do you get by "Well actually"-ing me on a completely innocuous aphorism?

Take it easy.
