Scientists have suspected that spare parts in the genome -extra copies of functional genes that arise when genes or whole genomes get duplicated -might sometimes provide the raw materials for the evolution of new traits. Now, researchers report in a study published online on September 3rd in Current Biology, that they have discovered a prime example of this in fish.
