The fighting hypothesis proposes that there is a so-called frequency-dependent maintenance of left-handedness. The main idea is that over the tens of thousands of years of human evolution, left-handers did have an advantage in fights due to a surprise effect. This gives them an evolutionary survival benefit since they win more fights.
One answer to this question is: Sports! But not at all types of sport. Their advantage is specifically in so-called antagonistic sports, in which two people compete with each other. These include all sorts of interactive ball games like tennis, table tennis, or badminton, but also various types of sports that involve fighting between two people, like boxing or fencing. In general, 10.6% of people are left-handed.
About 10.6 percent of people are left-handed ( Papadatou-Pastou and co-workers, 2020). It has been known for a long time that left-handedness runs in families. Two left-handed parents have a higher chance of having a left-handed child than two right-handed parents. Therefore, genes likely play a role in determining whether someone is born left-handed or right-handed. For a long time, scientists believed that there was just one handedness gene, but recent research has proven that this idea is wrong.
The study reveals that left-handed CEOs are associated with greater innovation success as measured by patent grants and other indicators, challenging previous notions about handedness in creative roles.
