Why are some people left-handed? - Daniel M. Abrams Let’s Begin…
Today, about one-tenth of the world’s population are southpaws. Why are such a small proportion of people left-handed -- and why does the trait exist in the first place? Daniel M. Abrams investigates how the uneven ratio of lefties and righties gives insight into a balance between competitive and cooperative pressures on human evolution. He looks into 500,000 years of human evolution and makes some fascinating suggestions about why there have always been left-handed people (and why we haven’t taken over the world quite yet).
