What hand do you use and do you use both hand? I am left handed and use both hands. Comment below
Right-handed people dominate the world, and it’s been that way since the Stone Age. How do we know? Researchers figured it out by measuring the arm bones in ancient skeletons and by examining wear patterns in prehistoric tools. In Western countries, lefties make up only about 10% of the population. Folks who favor different hands for different tasks (mixed handed) or who use both hands with equal skill (ambidextrous) are uncommon.
Scientists have long known that handedness is partly shaped by genes. But it wasn’t until 2019 that they identified differences in parts of the DNA of left- and right-handers. The study, which also analyzed brain scans of 9,000 British subjects, found that in lefties, the parts of the right and left sides of the brain that process language work in better tandem. Whether that makes left-handers more fluent speakers is still to be investigated.
