Is there any evolution theory in favor of darker eyes?
There is some evidence to suggest that darker eyes may have evolved as a result of the need for protection against sunlight. People with darker eyes have more melanin in their irises, which helps to absorb harmful UV rays. This may have been advantageous for people living in areas with high levels of sunlight exposure.
