Left-handedness - slightly more common in men than women - is thought to be determined by our genes, with some environmental influences. Left-handedness must have some advantages attached to it or it wouldn't survive in the evolutionary sense.

But the specialization of one forelimb leading to right- or left-handedness is better viewed as the result of natural selection.

So, for example, left-handedness has different connotations in different societies, just as ageing bodies have different connotations in different institutional contexts. Perhaps more important, when the collective data are pooled in wild chimpanzees, the ratio of right- to left-handedness is about 2:1, a value approximating the distribution in captive chimpanzees. Even at sport, where left-handedness can be a distinct advantage, schools can penalise us lefties. From the Hansard archive Example from the Hansard archive.
