And we have to guess that evolution didn't "respond".
Sooooo, we have some lack of fit, evolved over 10s of thousands of years for life as it was then and for the last ~5000 years in selected cultures faced with something quite different, powerful governments and armies, metals, weapons, tools, sailing ships, agriculture, domestic animals, ....
Supposedly for those 10s of thousands of years in parts of Europe people formed tribes and had some communal living, that is, in a long house, maybe 50-100 yards long 10-20 yards wide, with walls and roof forming a semi-circle. So, women and children got their socialization, security, lessons, skills, not merely from a couple, a bonded husband and wife living just as a couple, but from the tribe as a whole. I.e., now, for a lot for a person to learn and have, including shelter, we are depending heavily just on the mother and father.
