Why are most people right-handed but some are left-handed?

Abstract: Most people are right-handed, but about one in ten is left-handed. Handedness also relates

to language asymmetry, most people talking with the left half of their brain.The biological origins of brain asymmetry are obscure, although handedness undoubtedly runs in families and seems to have a genetic component, with few obvious environmental influences. In this talk I will overview some of what we know about handedness, and its relation to other asymmetries such as visceral asymmetries (heart, lungs, etc). A separate, important and related question concerns why and how brains are asymmetric, and what are the mechanisms that maintain left-handedness in populations, perhaps due there being advantages to being left-handed.”
