Why do Scandinavians have blonde hair and blue eyes?

However, it has been explained to me that the reason Scandinavians (as well as Celts) have light skin, hair and eyes is that this a natural selection that allows for the greater absorption of Vitamin D in environments where sunshine can be rare for large parts of the year.
Like elsewhere in Europe, Norwegians, Danes and Swedes have a range of hair and eye colours. There are two theories as to why many Scandinavians have blonde hair. What is this? One popular theory is it was caused by genetic mutations as a result of the lack of sunlight once humans began to spread north.
Why are blonde hair and blue eyes?
As the population grows and people have babies, the genes for less melanin will become more common. That makes the link between lighter eyes, hair, and skin tighter. So that’s why you see people with blond hair typically have blue eyes!
What diseases are Scandinavians prone to?
Like any country, there are common diseases in Sweden that affect the population.
- Cardiovascular Diseases. Ischemic heart disease is the most common form of heart disease in Sweden.
- Respiratory Diseases.
- Neoplasms.
- Alzheimer’s Disease and Dementia.
- Sexually Transmitted Infections.
The two groups that came to Scandinavia were originally genetically quite different, and displayed distinct physical appearances. The people from the south had blue eyes and relatively dark skin. Modern people of northern Europe trace relatively little genetic ancestry back to the early Scandinavians studied by us.

Why are there so many people with blue eyes in Scandinavia?
Because of the mix of western hunter gatherers with dark skin and blue eyes and eastern hunter gatherers with lighter skin in Fennoscandia 10–12.000 years ago. Finland and Estonia have the highest concentration today, followed by mid Sweden and Norway.
Why do most women in the world have blue eyes?
They are similar-looking, their skin is remarkably clean, huge blue eyes are pretty much the norm, and the symmetry of their faces is pretty ideal. Even Swedish girls’ blonde hair has an evolutionary explanation. Less pigment in the skin and hair allows for more ultraviolet B rays to enter and they are crucial to vitamin D production.
Are blonde hair and blue eyes part of the Nordic race?
Regardless, having blonde hair and blue eyes did not necessarily qualify someone as a member of the “Master race”, otherwise known as the Nordic race. German anthropologist Hans. F. K. Gunther estimated the racial composition of Germany to be 55\% Nordic, 20\% Alpine, 15\% Dinaric, 8\% East Baltic, and 2\% Mediterranean.
