Comment on "Global genetic change tracks global climate warming in Drosophila subobscura".
Balanyà et al. (Reports, 22 September 2006, p. 1773) build on earlier claims that chromosomal inversion polymorphisms of Drosophila subobscura are rapidly evolving in response to global warming. However, that conclusion is not adequately buttressed by their data, because they overlooked the lag between calendar and climatological dates created by the progressive lengthening of the growing season in their sampling approach.
