Human children learn a lot of things during the first year of life slower than other species. It’s possible that there are benefits to a certain learning speed.
Ok, I see. But I still don’t see why we need to sleep that much. It must have some other benefit then, and it cannot only be saving resources, as then babies should be able to trade sleep for food, no?
I checked, and it seems that land mammals’ babies also sleep more than gown ups, which would imply that learning slower than other species is probably not the reason why babies sleep that much. Interestingly, marine mammals’ babies seem to sleep less than grown ups.
It could be that babies sleep a lot because it’s not very useful for them to be awake for longer.
I don’t understand you; they have to literally learn everything.
