Population genomcis researchers at UC Davis have performed a whole-genome analysis of polymorphism and divergence in Drosophila simulans, a close relative of the lab rat of fruit flies, D. melanogaster. They found large fluctuations in polymorphism and divergence, which they've attributed to natural selection rather than changes in mutation rates. Many of these changes, they write, can be associated with gene expression, chromosome biology, and reproduction.
