Even researchleft-handed people In this situation, where they say: “There has never been a society in which people are in the majority”, the hand that we will actively use begins in our brain.
so that in early humans Even this situation has been observed!
This is a fact we have known for years whichever side we actively use; We are more likely to use that hand when performing our daily tasks. However, our brains are controlled in exactly the opposite way. In other words, the left hemisphere of our brain controls our right side.
Experts, this neurological He thinks that division of labor has existed since animals. The purpose of both hemispheres is therefore different. While one performs daily tasks, the other provides a self-protection mechanism.
Early humans may have used these limbs differently when they began to stand up and use tools. Stephanie Braccini, along with her team, conducted a study to support this view. In this experiment with chimpanzees, a strange situation was observed: Chimpanzees stand on all fours Although there is no single-handed preference, right- and left-handed preference varies among bipedal chimpanzees.
In fact, when the remains left by ancient humans were examined by archaeologists, no sufficient evidence was found that humans had a tendency to use their right hand. But in another geography, in Kenya Research shows that this situation is quite the opposite Homo habilis and Homo erectus The species was found to use their right hand.
According to experts, this situation has to do with language. Whenever language was actively used, people used their right hand ever since. Because, as we mentioned above, the brain works a little wrong. Everything related to language is controlled from the right side of the brain. It is thought that using the left side of the brain for language may have activated the right hand.
