Why are most people right-handed? Scientists link it to walking

If you walk into a café, you’ll see people sipping their morning coffee, biting into a croissant, scrolling through their phones, or flipping through a book. The odds are that almost all of them are using their right hands. It’s no surprise that about 90% of the people you meet are right-handed. But have you ever wondered why we use our right hands? No other primate species has this kind of preference. Our closest relatives, like chimpanzees, gorillas and orangutans, show individual hand preferences, but nothing like the near-universal right-handedness seen in humans.
