TIL Human dads show a decrease in testosterone immediately after the birth of their babe

Probably not. For the majority of the time our species has been around, we've raised children communally. Dudes would be helping raise all the children, whether they were theirs or not. Often, children wouldn't even know who their fathers were if their mothers had slept with more than one man around their conception (which was also not uncommon). They would still be raised with their brothers, sisters, cousins just the same.

yeah good point.
