Re: Baby gender
Another thing Id like to add here is the sexy-son hypothesis. The most fertile period of a woman is the day of ovulation, and the further away from it the less fertile the period. The sexy-son hypothesis states that women naturally prefer more masculine men during the most fertile periods of their cycle, ie, at ovulation. Also, it states, they prefer more care-giving men at less fertile periods of their cycle.
This way they can secure both the best genes, and the best care for their offspring. Of course, this is only an evolutionary fact, women don't change partners practically nowadays. However, this would mean that men are predisposed towards masculinity, being that women prefer masculine men at ovulation, which is when there are greater chances of having boy. And women are predisposed towards "care-giving", because the women would prefer care-giver fathers at the less-fertile times of her period, ie, before ovulation, a time which would increase the chances of girls being born.
As such, this could scientifically explain why men are masculine and women feminine and not the other way around. Men as such, would scientifically be the stronger sex (greater reproductive ability, greater ability to survive etc), while women would be the kinder sex (for lack of a better term).
Its funny, because just yesterday, I remember reading an article in the newspaper in which the author was blasting surah 4 of the Quran saying that the Quran's statement that men are the stronger sex is absurd. I dont think thats the case, men are not the better sex, they are just the stronger sex. It's amazing how the Quran never fails to be scientifically rational, considering how it was revealed more than 1400 years ago.
