A person’s gaze is the first thing we pay attention to when we first interact with them. It’s an instinctive thing: our eyes will meet those of the other to, from this visual cue, connect with the emotions and feelings that the other ex.
Given that, it is normal for people with green eyes to get our attention. Such a small part of the face is able to attract so much attention that it is common for parents to calculate the odds of having offspring with this trait.
But green eyes are not just a pure aesthetic, as they are fascinating in other ways as well.
Curious facts about people with green eyes
Below are the characteristics of people with green eyes that make this trait something so mysterious and fascinating.
1. The tint of the iris is one of the rarest
It is estimated that only 2% of the world’s population have green eyes, Which means that only scarlet, black or red eyes are less numerous. This can be due to several reasons.
On the one hand, it is very possible that only a sufficient number of green-eyed people have appeared in recent times, a few thousand years ago, which means that they did not have time to mix. many with the DNA strands of all human beings. The mutation is believed to have produced this characteristic appeared in tribes from central or northern Europe at some point in the Bronze Age.
On the other hand, the chances of having a boy or a girl with green eyes only exceed 50% if both parents also have this trait. If only one of them has it, they drop below 40%.
2. This trait first appeared in Europe
In addition to the rarity of this trait, it is estimated that more than half of people with green eyes live in Europe. Hungary and especially Iceland are the places where this physical trait is most abundant. Outside of this continent, some ethnic groups belonging to the Indo-Iranian zone also have high concentrations of green-eyed people, although it is not clear whether they have a common ancestor or the gene responsible for this tint appears in isolation. in Asia.
Even rarer cases with families with green eyes are found in certain regions of North Africa traditionally occupied by the Berber ethnic group, such as the Rif region in Morocco, Kabylia, Algeria, or Liquian in China.
3. Green irises take months to appear
Interestingly, it’s extremely rare for babies to already have green eyes. normally those who come to have them of this color do so after reaching their first year of life, And on the day of birth, they are blue or grayish. This is believed to be due to a certain genetic propensity for the distribution of melanin in the eyes according to specific developmental rhythms.
4. They have the most attractive eye color
Most questionnaire-based studies show that, at least for Western society, green eyes are the most aesthetic and attractive being those of the blue tone in second place. Perhaps the fact that they are scarce can influence this, as the Law of Scarcity tells us that we tend to place more value on what is hard to find.
5. Its coloring is not due to the pigments of the iris
As strange as it may sound, people with green eyes do not have them in this color because they have pigments of these shades located on these membranes. In fact, the amount of melanin, the substance that gives color to parts of the body, is relatively low compared to those with dark irises. If we were to assign a color to the iris, it would be closer to yellow.
What happens is that the shape of the eye and the slow effect it produces filters out certain wavelengths of light as it passes through this organ. It’s something similar to what happens when sunlight enters the atmosphere, making the sky appear blue or pink depending on how far away from the King of the Stars at any given time of day.
6. In the past, they have been discriminated against
Although it is considered an attractive feature today, there have been times in history when the rare and mysterious character of this shade was most striking. Consequently, many women were considered suspicious of being witches if they had green eyes. If to this were added the presence of red hair, the combination could lead to an easy execution.
