Well this is correct and this has more to do with patriarchy than 'genetics' per se ... in fact in a patriarchal society, it can be said that men did totally 'confiscate' the ownership of children ... it was usually said that a wife "gave children" to her husband ... hence it was of primary importance to radically control women's sexual acitivities by all kinds of means including the wife's sequestration inside the house, 'chastity belts' or even 'infibulation' (closing off or obstruction the genitals of, especially by sewing together the labia majora in females) which is still practiced in some African countries ... among those practices the veiling/hiding of women behind covering clothings like burqas and the like in Muslim countries to avoid 'encounters' with other men ...Andreas wrote:
A second, in my opinion minor reason probably is related to genetics: In the past, when there was no birth control, sexual intercourse with a different partner was naturally more likely to procude offspring with that (other) partner - therefore, especially in the case of men, it seemed desirable to make sure that the partner does not have sex with others.
Matriarchy is a totally different organization: children belong to the mother (which is quite 'natural' in fact), the biological father does not take care of his own children, he might not even know that he is the father (the role of father is generally taken by the mother's brothers or other males in the matriarchal family) ... therefore the problem of controlling who is the biological father does not arise ... and women are totally free to have sexual relationships with the men she loves ... the notion of marriage does not exist, there is no permanent relationship instituted between men and women ... when a man loves a woman, he is 'invited' in her room at night, then at morning he goes back to work in his family (his mother, sisters and brothers ...)
Maybe Alex would love to live in a matriarchy

Personally I see this evolution as a major shift in human society, it will solve a lot of conflicts, because I really don't see how there could be peace when half of humanity is considered to be inferior to the other half ...
