On May 22, a new episode of NICO's popular program was aired. The topic of this episode sparked heated discussions, "Why are most humans right-handed?" After the program team irresponsibly discussed it, it was "confirmed" that the reason is related to speaking. Let's take a look at it. First of all, according to incomplete statistics, there are about 7 billion right-handed people in the world, accounting for more than 90% of the total population. It is well known that the left brain controls the right half of the body, and the right brain controls the left half. Modern physiology shows that the human brain is divided into two parts: the left brain and the right brain. The left brain is responsible for language and abstract thinking, and the right brain is responsible for image thinking, with music, image, integrity and geometric space identification ability. So it goes without saying that right-handedness is related to speaking. ·Then tracing back to ancient times, about 60% of the ancient Tanzanians 1.8 to 2.4 million years ago were right-handed, while by 2,500 years ago, the number had reached over 90%. The reason for this is that after the ancients learned to speak, the left brain evolved faster. Although there is no definite evidence, if you think about the left-handed people around you, there seems to be quite a few who have become painters and musicians. |
