Introduction
Eye color is a trait determined by genetics and is one of the most noticeable features of a person’s physical appearance. While some people have brown eyes, others may have blue, green, hazel, or a combination of two or more colors. But which eye color is the most common? This article looks at the prevalence of different eye colors across the globe and investigates why certain colors are more popular than others.
Exploring the Most Common Eye Colors Across the Globe
An overview of the most popular eye color in the world reveals that brown is the most common, followed by blue and then green. In fact, according to a study published in Human Genetics, 79% of the world’s population has brown eyes, while 8-10% have blue eyes and only 2% have green eyes. The remaining 1% have other colors such as gray, hazel, or amber.
A look at the prevalence of different eye colors reveals that they vary widely from region to region. For example, in Europe, blue eyes are more common than brown, whereas in Asia and Africa, brown is the most prevalent. In the Americas, both brown and blue eyes are equally common. Interestingly, in certain countries such as Iceland and Finland, almost all the population has blue eyes.
So, which eye color is the most common around the world? The answer is brown. As previously mentioned, 79% of the global population has brown eyes, making it the most popular eye color worldwide.
The Most Common Eye Color and Why It’s So Popular
Now that we know that brown is the most common eye color, let’s take a closer look at the genetics behind it. The color of our eyes is determined by a gene called OCA2. This gene produces a protein called P-protein, which is responsible for the production of melanin in the iris of the eye. Melanin is a pigment that determines the color of our eyes.
The OCA2 gene comes in two versions. One version produces more P-protein, leading to darker eyes, while the other produces less P-protein, resulting in lighter eyes. Brown eyes are the result of the ‘darker’ version of the OCA2 gene, while blue eyes are the result of the ‘lighter’ version. This explains why brown is the most common eye color because the ‘darker’ version of the gene is more prevalent.
Understanding the distribution of eye colors worldwide can help us gain insight into the evolution of the human species. Scientists believe that the OCA2 gene evolved over time to adapt to changing environmental conditions. For example, those living in sunny climates would have developed the ‘darker’ version of the gene to protect their eyes from the sun’s rays.
Conclusion
In conclusion, this article has explored the most common eye color around the world. We discovered that brown is the most popular eye color, followed by blue and then green. We also looked at the genetics behind the most common eye color and discussed the distribution of different eye colors around the world. Finally, we considered the impact that this information has on society.
Overall, this research provides useful insights into the evolution of the human species and the prevalence of different eye colors. It also helps us understand why certain eye colors are more common than others. More research is needed to better understand the genetic basis of eye color and its implications for society.
