I wish I could remember where this observation came from, which was that when you have (as many languages do) 'gender-indexed' speech, the mother, as care-giver, has to be fluent in both, in order to teach male children how to appropriately communicate. This would obviously have a great impact on a lot of other things that one could speculate on, but probably impossible to prove.
I tend to think that all languages have some sort of gender-indexed differences so these effects are going to exist in all cultures, but it is the accretion of cultural behavior/norms rather than something in the chromosones.
Just looked at Michael's handwriting, really has a French feel to it. I remember being confronted with French handwriting when I taught there and was pretty amazed
