Are Blue Eyes Endangered?

The video explores the history and genetics of blue eyes, a trait that is becoming rarer but unlikely to disappear. It explains that blue eyes originated from a genetic mutation in the OCA2 gene, affecting melanin production in the iris. This mutation causes light scattering, making eyes appear blue. The spread of blue eyes in Europe may be due to mating patterns and potential advantages in northern climates. Blue eyes are inherited through recessive alleles, and their prevalence is decreasing as populations mix. Despite this, blue eyes will remain a minority trait.
