The journal Heredity is publishing a special issue on experimental evolution, under the guest editorship of Graham Bell. The goal of experimental evolution is to understand the mechanics of adaptation by observing the outcome of natural selection in simplified laboratory microcosms. The experimental approach allows us to study fundamental features of evolution such as the fixation of beneficial mutations, the extent of specialization, the repeatability of adaptation and the effect of sex. The May issue of Heredity marks the great expansion of the field in recent years. It features mainly work on microbial and viral systems concerned with the genetic basis of adaptation, and the complications introduced by conflicting sources of selection and complex social interactions.
