Interbreeding or genetic manipulation.
Everyone with blue eyes inherited a tiny genetic "switch" that dilutes brown pigment in the iris. This mutation, found in all blue-eyed people, emerged 6,000-10,000 years ago. A single founder, a common ancestor in whom the mutation first spontaneously occurred.”
The scientific basis for the “blue eye theory” is the discovery of a specific genetic mutation that affected the OCA2 gene’s function. This mutation did not occur within OCA2 itself but in a neighboring gene called HERC2, which acts as a regulator for OCA2. HERC2 contains a region that serves as a genetic “switch,” controlling how much the OCA2 gene is expressed and thus how much melanin is produced in the iris. The original, unmutated version of this switch ensures robust melanin production, resulting in brown eyes.
The blue eye mutation involves a single change in the DNA sequence within the HERC2 regulator. This alteration prevents HERC2 from properly activating OCA2, leading to a significant reduction in the amount of melanin synthesized. Genetic evidence suggests that virtually all blue-eyed individuals share this identical mutation. This molecular uniformity points to a single founder, a common ancestor in whom the mutation first spontaneously occurred. https://scienceinsights.org/what-is-the-blue-eye-theory-a-look-at-its-origins/
Blonde hair is believed to have originated around 11,000 years ago during the last Ice Age, as a result of genetic mutations that allowed for lighter hair colors in populations living in Northern Europe.
Napoleon Bonaparte was approximately 5 feet 6 inches tall (169 centimeters) in modern measurements, which was around average height for his time.
Average height varies by country and region, influenced by factors like genetics and nutrition. For example, the average male height in the United States is about 5 feet 9 inches, while in the Netherlands, it is around 6 feet.

How many UFO anomalies does the Netherlands have in its history?
I’m exhausted so I’ll be short. Unlike Napoleon. The claim he was short was a tactic during the war. He was average size for the time.
As for the age of the existence of light skinned blue eyed blondes. Here’s a link from 2025.

I believe this to be the case.
No
That actually makes a lot of sense.
Anything is possible. Probable though, no.
Humans have evolved for our environment over time.
We have a pigment called melanin, usually known in our skin but it’s also in our eyes. It serves the same purpose-protect us from sunlight radiation. Further north you go, less sunlight, less melanin. Then it becomes influenced by sexual selection over time if populations find it desirable, and it propagates more and becomes less of a random mutation, like the *HERC2* gene.
Other people migrated north and didn’t lose their skin pigmentation as much as the proto-Europeans did, like the Inuit, but many of them have green or blue eyes as well as thicker eyelids, which is an adaptation to the cold windy weather
Yes. Very likely.
Wouldn’t basic biology make it impossible for interbreeding?
