Umm... I thought the "decision" was made by the individual spermatozoa.

You are RIGHT. There are some studies that suggest that there are different foods you can eat before pregnancy that could influence which gender your future baby will be. And Different douches. Baking soda if you want sons, vinegar if you want daughters. My mother used vinegar and had three daughters. I tried to foods thing and it worked for me. Coindidence maybe!

That's a damn good point, maybe male embryos are less likely to implant in thinner women for some reason? I must admit, it makes sense as an adaption (not the same as saying that it actually happens of course). A single male can impregnate many females so having lots of males around is a luxury which in times of starvation can be dispensed with.

I'd agree. Why bother with science? No more need for Ultrasounds either. If you weigh less than 100lbs, then you're going to have a girl.
