In our country India, along with diverse cultures, there is a lot of diversity in the physical colors of the people – some are fair, some are dark, some are wheatish. But whenever the name of the continent of Africa comes to our mind, the first thing that comes to our mind is the dark black color of the people there. In many parts of the world, due to ignorance and conservative thinking, people consider it to be bad luck or a curse, but from the point of view of science, the truth is exactly the opposite.
In fact, this dark color is a precious and scientific gift of nature to the people of Africa, which keeps them completely safe even in the extremely difficult weather there. Let us know the interesting scientific reasons behind this.
Melanin is the real superhero of our skin.
What will be the color of our skin, hair and eyes depends on what is present in our body. ‘Melanin’ The name is determined by a natural pigment. The greater the amount of melanin in the body cells, the darker or darker the skin color will appear.
The geographical position of Africa is such that direct and very strong rays of the sun fall there, due to which the amount of dangerous ultraviolet (UV) rays in the atmosphere is very high. In such a situation, the excessive melanin present in the body of the people there acts like an excellent shield. It absorbs these dangerous rays before they penetrate deep into the skin, due to which the inner cells and DNA of the skin remain completely protected. This is the reason why people of African origin have the lowest risk of skin cancer in the world.
Main benefits of dark skin color
Nature has given people with dark skin many protective benefits that people living in cold areas do not have:
How did the color of humans change thousands of years ago?
According to the theories of evolution and scientists, Africa is considered the cradle of the entire human civilization. That means millions of years ago, our ancestors lived there and all of them had dark complexion. But as the human population grew, people started migrating out of Africa to cooler and less sunny areas of Europe and Asia.
evolution journey of color change
When humans arrived in countries where winter was long and there was little sunlight, their body’s needs changed according to the environment there. In areas with less sunlight, the body started having difficulty in producing Vitamin D which is necessary for strengthening bones. In such a situation, nature has gradually reduced the level of melanin in their body during the evolutionary process of thousands of years, so that the body can easily absorb the remaining sunlight. Due to less melanin the complexion of the people of cold countries became fair.
India’s geographical diversity and our color
If we talk about India, our geographical location is so unique that here you get to see a very beautiful and diverse mix of colors. The region of North India is close to hilly and cold areas, hence the complexion of the people there is slightly fair or wheatish. On the contrary, as we move towards South India, sunlight becomes brighter and more direct due to its proximity to the Equator. For this reason, the level of melanin in the skin of the people of South India is naturally slightly higher, which is the main reason for their dark complexion.
Importance of dark color in modern times
In today’s time, when the temperature of the whole world is increasing due to global warming and UV rays are becoming more dangerous due to the loss of ozone layer, then people with dark skin are the safest because of this protective shield of nature. Science clearly says that every color in the world is beautiful and nature has a very thoughtful and important reason hidden behind every color.
