Fact of Life #8: A mother’s diet can influence the sex of her unborn child. Link
And here I was thinking that the only way to choose the sex of your baby was to wait until you were rich enough to afford to pay someone to genetically engineer a designer baby for you.
That’s crazy stuff, isn’t it? How cool is that.
The article has a bunch of stuff about how this has implications in developing countries, where mothers eat less, which correlates to more girl babies and less boy babies. And it also has a little bit of speculation as to why this is. From an evolutionary standpoint, it benefits more to have boy babies when the conditions are good, because a male can father far more babies in his lifetime than a female can produce in her lifetime. On the other hand, it benefits more to have girl babies when the conditions are bad because females reproduce more consistently.
Woww. That’s pretty rad.
