Population genetics: the signature of selection.
There is hope that the structure of molecular variation within populations can give evidence for recent adaptive evolution. New work on Drosophila genes that seem to have been subject to adaptive changes illustrates the difficulties in calculating the statistical significance of data trends that seem to show this.
