Why are some people left-handed? An evolutionary perspective.

Philosophical transactions of the Royal Society of London. Series B, Biological sciences - 12 Apr 2009

Llaurens V, Raymond M, Faurie C

Abstract excerpt

Since prehistoric times, left-handed individuals have been ubiquitous in human populations, exhibiting geographical frequency variations. Evolutionary explanations have been proposed for the persistence of the handedness polymorphism. Left-handedness could be favoured by negative frequency-dependent selection. Data have suggested that left-handedness, as the rare hand preference, could represent an important...
