About 90 percent of people are right-handed, but why are some people left-handed? However, that is not the real question. Why are we even have a preferable hand? Should we be able to do things with both of our hands equally? Some believe that it has to do with language. Most people handle language in the left hemisphere of the brain which is why motor skills got grouped in when we started speaking. However, this theory doesn’t explain the left-handed. New research shows that gorillas and chimps also have a preferable hand. It looks that we started using one hand over the other more through the evolution process.
