Seems that all blue-eyed people (which would include Rico) are related: "Danish researchers have concluded that all blue-eyed people share a common ancestor, presumably someone who lived 6,000 to 10,000 years ago."
"Originally, we all had brown eyes," according to Professor Hans Eiberg of the University of Copenhagen. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a 'switch,' which literally 'turned off' the ability to produce brown eyes."
