Yes, yes, this. I've in the past wondered how such a high percentage of women die during childbirth pre-modern era could make sense on an evolutionary level. Surely, it would be more beneficial in nature to have both parents. But evolution doesn't care about the life of the adult, only that it carried on viable and successful offspring. Humans are very social and a child can just be raised by someone else in the 'pack.'
My favorite example is the luna moth. A beautiful moth who, as an adult, has no mouth and has to mate before they slowly die from starvation. Nature can be cruel.
