World And Lefty People
Every 1 person out of 10 in the world is left-handed. What is The Mystery Behind People Being Left-Handed? In many parts of the world; it is very usual to teach children to make habit of using proper hands for certain actions. So, why we have been seeing Left-Handed people?
Even in many languages, the word right stands for correct and good where the word left represents a wrong or evil. If the “left” is wrong in many cultures then why we see left-handy people among us. Even the Archaeological survey has proven that Left-Handed people existed in our society since 5000 years ago. Is it some sort of unsolved Mystery?
The Science behind this phenomena
If people think that it just the random selection or choice that completely depends upon people. By the way, it’s not up to the person that he wants to become the right-handed or left-handed person. Even though this lifelong habit of a person is actually predictable before the birth of that person.
One theory is that it depends upon fetus position when he/she is in his/her mother’s womb. Some believe that it because of genetics, yet the examples/ proof found of dissimilarity between twins. Both Left-handed parents also play an important factor in deciding a child to be a lefty or not.
The Role of Evolution
Why evolution has produced and maintained this small amount of Left-Handed people over the course of 5000 years?
Actually, there are several evolution theories which unfold The Mystery Behind People Being Left-Handed and; explain how the person Left-Handed or right-handed. However, actually reflects the balance between both throughout human evolution. As the Left-Handed smaller in proportion, it turns out to be an advantage for them due to their fighting hypothesis.
Competitive and cooperative nature role played a vital role in human evolution. The competitiveness is turned out to be an advantage for the left-handed. On the other hand, cooperativeness doesn’t navigate in favour of lefties. For instance, the majority of an instrument of everyday life has been designed according to right-handed because a portion of a population is right-handed. And hence lefties require more time or face more problems to do things or face difficulties become comfortable with these things. They turned out to be less successful in the cooperative world. This is how evolution has played out competitive and cooperative simultaneously over time and balanced it.
