This is the bottom of it all. "Man the Hunter" is a control tact used by sexist men. The advent of technology and internet has exposed many lies used against women.
Another sketchy fallacy about women only tending to children is that in those days while men hunted, women were farming and we know how massive agriculture was then. Mothers and daughter were farming to support their husbands and sons in producing food resources in large scales.
But of course, no one mentioned women’s contribution in agriculture at all. Even to the point women were sold as slaves just like men to crops and livestock farmers.
