Caption: An Indian fantail -- one of 350 rock pigeon breeds -- displays a type of head crest known as a peak crest. Researchers from the University of Utah and from China, Denmark and Texas identified a single gene that, when mutated, apparently causes head crests to form in numerous pigeon breeds. It was part of a project that decoded the genetic blueprint of the rock pigeon, among Earth’s most common and diverse bird species.
