Really? Numbers please. Btw I read an interesting thought on that from Nassim Taleb: that this was one of the greatest achievement of the church to give almost everybody access to a womb (by enforcing monogamy), thereby eliminating a lot of cause for conflict. In some societies rich/powerful men can have several women, and accordingly the poorer men get none. Genetics apparently also show that historically it was twice as likely for women to procreate as for men (meaning most of the time a lot of men never had kids, but most women had kids).
