Only around 5% of the world’s population have hazel eyes. Yet a 2009 study found that 55.2% of their Spanish cohort had hazel-green eyes. This eye color is also more common in Portugal than the global average. But why is there such a concentration of hazel eyes in the Iberian peninsula compared to most other parts of the world? And is the evolution of hazel eyes connected to the genetic history of Iberia?

Now there are a two main types of hazel eyes.
