How the fruit fly changed (some of) its spots.
Recent results show that the establishment of wing melanization patterns in Drosophila depends on the veins. While several genes have been shown to play a role in melanization, changes in a single gene - the one encoding tyrosine hydroxylase - are sufficient to generate novel pigmentation patterns.
