The fourth chromosome of Drosophila melanogaster was believed to be free from variation and meiotic recombination, leading to several theories about its selection and evolution. In the January 4 Science, Wen Wang and researchers at the University of Chicago challenge these theories with their discovery of regions of variation along the chromosome (Science 2002, 295:134-137).
