ONLY 2% OF THE WORLD’S POPULATION HAS GREEN EYES. WHY?

This eye color is more common in women than in men, and its existence is only recorded in Europe and in a population of European origin.

In addition to Europe, only genes for the formation of this eye color were found in the Pashtun populations from Afghanistan and Pakistan.

Although scientists are still studying the origin of differentiating eye tones (such as blue, green or gray), one of the latest theories by Italian geneticist Luigi Cavalli-Sforza, a professor at Stanford University, suggests that this mutation Color responds to sexual selection.

As El Economista reports, when there are more individuals of one sex than the other, mutations occur to compete in the 'fight' for a partner.

That is, the evolutionary process itself has given rise to shinier, more striking shades of eyes to stand out from the usual brown eyes - which more than 50% of the world's population has.

Saisi!
