My thoughts...did Science have more to do than culture with the matriarchal system - and of naming children after their mothers and not the paterfamilias? Are maternal genes more dominant in the long run? Any clues from the Vedas?

Was amazed to discover that all foetesus are female until a certain term, when male characterisics begin to dominate in those foetuses which will be born as sons. Is this another clue? Probably not....interesting, though......
