What's Your Eye Color REALLY Saying About You? - Think Science

[Rhiannon12866]

Explore the science behind eye color variations. Discover how melanin and genetics influence everything from vision to human migration patterns. Learn about the surprising evolutionary history behind each eye color.

Did you know that every single person with blue eyes can trace their lineage back to one specific ancestor who lived 6,000 years ago? Or that brown eyes act as a natural "sunglass" shield against UV radiation?

Your eye color isn't just a random roll of the genetic dice. It is a biological map of your ancestors' journey, their survival strategies, and the environments they conquered. In this video, we break down the evolutionary science behind every eye color—from the most common to the exceptionally rare.

We explore why brown eyes dominate the equator, the "genetic accident" that created blue eyes, the chemical instability of green eyes, and the truth about whether "black" eyes actually exist.

In this video, we cover:

The Brown Eye Advantage: How melanin protects vision and DNA.

The Blue Eye Mutation: The 10,000-year-old mystery of European migration.

The Rarity of Green & Gray: Why these colors are chemically unique.

The "Wolf" Eyes: The science behind Amber and Hazel irises.

Heterochromia: The genetic anomaly that creates two different colored eyes. - 12/20/2025.
