Billionaires have more grandchildren through their sons than through their daughters, because the status advantage is more reproductively valuable to the sons. Therefore, it would be adaptive for the mothers of their children to bear more sons than daughters. But surely that can't be; mothers can't control the sex of their children.
Oh but so it is: billionaires have 60% male children.

An article in the Independent newspaper reports that pests have started thriving on poisons genetically implanted in crops.
It seems that before, the organic pesticide used, was effective because it was only sprayed occasionally (once or twice a year) and the pests didn't have time to develop resistance.
With the pesticide being accessible throughout the whole crop-cycle, the pests have adapted, and now thrive on the poison, which they now regard as a food source, growing even larger than normal, and rendering a weapon in the arsenal against pests, entirely ineffective.
