Monkeys Just Helped Solve One of Humanity’s Biggest Mysteries, but Lefties Remain the Odd Ones Out

Monkeys just helped Oxford scientists crack one of humanity’s oldest mysteries – why 90% of us are right-handed. The answer, it turns out, is tied to two big evolutionary leaps, walking upright and growing bigger brains. But if you’re a lefty, don’t expect any clarity just yet. You’re still the odd one out, and science isn’t entirely sure why.

Monkeys Just Helped Solve One of Humanity’s Biggest Mysteries, but Lefties Remain the Odd Ones Out. Monkeys just helped Oxford scientists crack one of humanity’s oldest mysteries – why 90% of us are right-handed. The answer, it turns out, is tied to two big evolutionary leaps, walking upright and growing bigger brains. But if you’re a lefty, don’t expect any clarity just yet. You’re still the odd one out, and science isn’t entirely sure why. Researchers at the University of Oxford spent years digging into the origins of handedness, and their findings, published in PLOS Biology, finally give us a solid explanation for why the vast majority of humans favor their right hand. According to LADBible, the team analyzed data from 2,025 monkeys and apes across 41 different primate species, looking at everything from tool use and diet to brain siz...
