In the wild, it would have worked like this: If a woman only sleeps with one man, it guarantees that it’s that man’s child. However, if a woman sleeps with multiple men, it could be anyone’s child. Raising a child requires a lot of time and energy, so all of the potential fathers would have a reason and an excuse to not raise the child, because it may not be theirs, and that effort that could have gone to a guaranteed biological child would be wasted.
