Just when you thought the pressure on mothers couldn’t be any greater, science and the media machine that interprets it have come up with a brand new Darwin-shaped stick to beat us with. According to a “simple mathematical model” published this week, the rising rate of caesarean sections could be explained by an evolutionary trend whereby the procedure itself perpetuates small pelvises in women.
Babies who would previously have died during childbirth because they were unable to fit their large heads through their mothers’ narrow pelvises are now saved by caesarean sections. According to the theory, the small-pelvis genes of the mother are then passed on to the next generation, defying natural selection. Researchers predict that this will lead to an evolutionary loop requiring increasing numbers of caesareans as the generations go by.
