What is the Origin & Reason for Blue Eyes?​

 

[Forest Cat]

According to the map, I live in the epicenter of blonde hair and blue eyes. I have always heard that it's simply because of the lack of sun here, a natural adaptation. That's probably a simplified explanation.

Judging by their eyebrows, both of those extremely filtered women aren't natural blondes.

Blue eyes and blond hair tend to be rare because any gene that produces any other color masks it.

"Brown" is darker, so brown + blond = brown.

This why you tend to find more blue eyes and blond hair in more isolated areas.

Lack of sunlight led to a lack of Vitamin D in the originally dark African/ME skin. Natural adaptation via mutations followed, producing and using less melanin, affecting skin, hair, and eyes. You generally need two parents with the genetics to get blue/grey eyes. Most true blonds experience darkening and then greying/whitening over their lifetime. Hair other than head hair may not be blond. With this adaptation, certain autoimmune and other diseases become more likely. KITGL gene mutation for blond hair, mutation of the OCA2 for blue eyes (started only 6000-10000 years ago).

I was already subscribed to that guy's channel but hadn't seen that video. What I liked about him was he was really sharp/smart and I could barely understand him!

Do you yourself have blond hair and blue eyes?

Do you yourself have blond hair and blue eyes?

No, around 50% of men here are not blond or blue-eyed. I'm one of those, dark hair, green/brown eyes. We're outcasts, not blond enough. We roam the forest and live off the land.

So that's why you're living in the forest, makes sense!

Interesting reading. It may not have been a matter of migration of such peoples, so much as a matter of how they physically evolved once they got there.

At least this is one explanation:

Yes, I was banished to the countryside for my lack of blondness.

Must be a "shady" person then...lol.

Then again maybe he's really from Lake Tahoe! Lots of shade there too.

Well you see @Jonn when a man and a woman fall in love....... and that's the story of the birds and the bees.

Some women use makeup to darken their eyebrows.

From memory, I believe other colours are dominant.
The same with skin pigment.

That suggests that local adaptation to the high-latitude climate associated with low levels of sunlight and low temperatures took place in Scandinavia after these groups arrived. In fact, this is in agreement with the worldwide pattern of pigmentation decreasing with distance to the equator.

True, some - but it's a minority. The vast majority of blondes have dyed hair, and the eyebrows are a giveaway.
