Blue-Green Eyes: Learn About This Rare Color | advice from boys (2023)

Blue-green eyes are rare.

blue green Eyesthey are amazing to watch. Part of the reason they command our attention is that they are extremely rare. Although the science is somewhat scattered, the current isInvestigationsuggests that only about 3-5% of the human population have true blue-green eyes.

This is incredible considering there are over 7 billion people on the planet. In addition, blue-green eyes are unusual, as the human species only has three predominant shades of color:

• azul
• verde
• braun

Blue-green eyes also capture our imagination because these two colors are rare. As you will read later, most people on this planet have brown eyes.

Eye colors: the three most important

Before we learn more about the rarity of blue-green eyes, it might be helpful to take a look at the three primary colors mentioned above: blue, green, and brown.

Blue eyes

Studying blue eyes is a hot area of ​​science. Currently we estimate that about 8% of the world's population has blue eyes. It's important to say that we still don't know for sure.

If that number is correct, it means that nearly 56 million people will be born with a shade of blue.

People from Northern Europe, especially Scandinavia, seem to have the bluest eyes.

Keep in mind that there are different shades of blue, including aquamarine, crystal and "sky blue". And there can be a mixture of different hazelnuts that produce hazelnut.

Where do blue eyes come from?

There are several theories about what causes blue eyes. As we see certain ethnic groups with more blue-eyed people, it is believed that there is a genetic factor at play.

For example, people born in Germany, Ireland, Scotland, England and Northern Italy seem to have a higher proportion of blue eyes compared to other countries.

In fact, regional studies suggest that around 70% of people native to these areas have some shade of blue-green. Some people refer to this as seaweed ink.

It used to be thought that if a person was born with blue eyes, it meant that their father had a dominant gene. In fact, this theory gained so much confidence that it was taught in most schools and universities.

Think back to your biology classes. Remember?

However, in 2008, an article appeared in theamerican journal of human geneticsit took away a lot of what we thought we knew about eye color.

Current thinking now suggests that there are 16 genes that affect eye color and having a family member with a dominant gene may not be as important.

origins of blue eyes

Debate over the origins of blue eyes continues. Recent research points to the possibility that blue-eyed people share a common ancestor; postulated by the University of Copenhagen.

Through a series of genetic mutations that occurred over millions of years of adaptation, blue eyes became part of the human race.

We still don't know if the blue color in eye color has a specific function.

Green eyes

If you have green eyes, you feel like you are in a very special club. This is because current research suggests that only 2% of the world's population has green eyes.

We see people with green eyes all over the world. The highest concentration of this color (including brown eyes) is found in most parts of Europe. Interestingly, we also see shades of green in West Asia.

If you do the math and break down the 2% mentioned above, that means that only around 140 million of the 7 billion people on the planet have any shade of green.

Where do green eyes come from?

Like blue eyes, green eyes are considered part of the human species due to genetic adaptations. Humanity as we know it has only existed on Earth for about 200,000 years.

But if you plot human ancestry on a geological time scale and account for adaptation, we can pinpoint our beginnings to nearly two million years ago, during thepleistocene epoch.

At some point during the evolutionary period, green eyes appeared as part of humanity. Some scientists believe that a functional aspect was involved, possibly as a result of extinction events. We still don't know the real answers.

What is clear is that green eyes are less common than blue eyes and that we see different shades of blue-green in many people. This color is more common in Caucasians. Why this happens remains a mystery.

Brown eyes

Brown eyes are the most striking color on the planet. As with the other brows mentioned, we're not sure how many people have brown eyes. Current research suggests that around 65% of the world's population has some form of brown pigmentation in the iris.

We see brown-eyed men and women all over the world. The highest concentration of people with brown eyes, including greenish brown eyes, are found in southern Europe, Africa and across Asia.

People in South America tend to have darker eyes. The tectonic plate shift could be the causal reason why Pangea broke apart and formed Africa and South America. Watch this short video below to learn more.

What is the origin of brown eyes?

Like the eye colors mentioned above, brown eyes are believed to have been present on Earth since the earliest manifestations of humanity. Some scientists believe that most early humans were some sort of brown color; but they are not sure why.

What's interesting is if you look at the eye color, most monkey eyes are usually brown, some have a hazel brown tooth.

Brown is believed to have been a camouflage color as part of human adaptation, allowing early humans to hide in the bush during the hunter-gatherer phase of evolution.

blue green eyes

All the material mentioned above led us to the topic of blue-green eyes. What exactly are they and why do some people have one blue eye and one green eye?

Blue-green eyes are no different in origin from the other eye colors mentioned above. They are believed to be part of human evolution as part of adaptation.

What's different about blue-green eyes is the nickname they often use; Brown eyes. But what many people don't realize is that it's not necessary to have a combination ofblue and greenhas "hazelnut". That's because hazel eyes can contain blue-brown or greenish-brown.

Origin of blue-green eyes

Perhaps the most intriguing part of blue-green eyes has to do with where they come from. Research suggests that the mixed hue of blue and green first appeared in humans about 10,000 years ago.

If you take into account the geological time scale mentioned above, that wasn't that long ago!

Several scientists believe that the blue-green adaptation occurred sometime after the last ice age, around 8,000 years ago.

Here is a direct quote from the research that appears inhuman genetics2008 on this topic:

"A single haplotype, represented by six polymorphic SNPs covering the 3' half of the HERC2 gene, was found in 155 blue-eyed individuals from Denmark and 5 and 2 blue-eyed individuals from Turkey and Jordan, respectively."

If you break scientific jargon, scientists are basically saying that blue and green may have come to us from Scandinavia, but at some point there was some mixing with humans mating in modern Mesopotamia.

strange blue-green eyes

True blue-green eyes are extremely rare. To qualify as cyan, you must have a hint of both colors in your iris. This is a distinctive feature that distinguishes people with brown eyes, where green or brown stands out.

A person can also have blue-green eyes if each eye is a different color. For example, actor Josh Henderson has one blue eye and one green eye. Very, very rarely.

Why do some people have one blue eye and one green eye?

Scientists believe that some people are born with different eye colors (also known as mixed eye colors) due to genetics. The name of this condition isheterocromia.

Honestly, we don't know the answer. The DNA of both parents is part of the child's genetic material, which may have undergone some type of alteration during the zygote's development phase.

There are no in utero tests that currently explain what is going on.

THE SCIENCE OF BLUE EYES

Melanin content in eye color of people with gray, green, amber, hazel, brown, blue, violet and gray and black eyes

The science behind blue-green eyes

If a person is born with blue-green eyes, this is a direct result of genetics. As mentioned above, there are 16 known genes involved in this process.

melanin and eye color

There is a substance called melanin that is common to all human beings. Composed of a complex polymer with the amino acid tyrosine, this chemical has a lot to do with how others perceive your eyes.

Melanin-based reaction

The concentration of melanin in your eyes reflects backlight from its source. The richer the melanin, the deeper the color a person sees.

However, if you have blue-green eyes, it is possible that what is reflected is black. This is because the base of the iris cannot project these two eyes at the same time.

Light blue-green eyes.

Part of your eye contains something calledIris. This iris itself consists of two layers, one at the front and one at the back.

Stuck between the two is thestoma, which is composed mainly of collagen. This information is important to know because eye color, like blue-green, is not determined by the iris itself.

Rather, hue is related to how the aforementioned melanin reflects backlight.

Light reflection can be natural or artificial. In either case, light itself greatly affects how others perceive your eye color.

eye color chart

When you look closely at someone with blue-green eyes, doesn't it look like their color is changing right in front of you? This is due to the way light is reflected off the melanin base.

Or to put it scientifically:Rayleigh Scattering.

While this may seem like a fancy term, Rayleigh scattering is a phenomenon that determines how light is diffracted and scattered. That's why you experience a blue sky instead of a red one like on Mars.

Here's a video that might help better explain how this dynamic works.

Blue and green eye changes

There are other factors that affect how others perceive blue-green eyes. Examples include:

• rejoice
• Clothes
• The image
• wetter
• medical reasons

This may sound strange, but remember that eye color is almost always perceived by the presence of light. The intensity of this color also depends on the chemical reactions taking place in the body.

When you're in a bad mood, your eyes look more watery and therefore clearer. If someone with blue-green eyes wears a light-colored shirt, their eye color will appear darker.

The same goes for the weather; means the amount of sun in the sky. In general, the more sunlight that comes in, the lighter your eye color becomes.

Can you change the color of your eyes?

There are artificial means by which people change their eye color. This is mostly done through the use of contacts. But if you have really dark eyes, like dark brown, wearing contact lenses can make you look a little weird.

Blue-Green-Eye-Mythen

There are several myths associated with blue-green eyes. Here is just a small sample:

• Blue-eyed people are smarter.
• Blue-eyed people are more attractive.
• Blue-eyed people can hypnotize people.
• Blue-eyed people live shorter lives.
• Blue-eyed people are part Latina
• Blue-eyed men are mostly Scorpios
• Blue-eyed women are mostly Pisces

Just for fun, here's a survey that asks some questions about eye color. Please note that this is for entertainment purposes only and should not be considered scientific in nature.

Do blue-green eyes come from aliens?

Some people think that a combination of blue and green eyes is the direct result of extraterrestrial interference with planet Earth.

Obviously, there is no evidence to support this claim, but that doesn't stop some people from believing it. FYI: Some people think that owls are also from aliens.

The reason the rumor arose largely came from urban myths. Since blue-green eyes are the most unusual, some people have looked for a supernatural explanation. Stupid, but that's how this gossip started.

final thoughts

Eye color is determined by many factors, including genetics, melanin pigmentation and light phenomena.

With each passing year, scientists are learning more and more about the origins of eye color, including blue-green eyes.
