Experimental Evolution

Recent decades have seen a significant rise in studies in which evolution is observed and analysed directly - as it happens — under replicated, controlled conditions. Such 'experimental evolution' approaches offer a degree of resolution of evolutionary processes and their underlying genetics that is difficult or even impossible to achieve in more traditional comparative and retrospective analyses. In principle, experimental populations can be monitored for phenotypic and genetic changes with any desired level of replication and measurement precision, facilitating progress on fundamental and previously unresolved questions in evolutionary biology. This special feature brings together 10 invited papers in which experimental evolution is making significant progress on a variety of fundamental questions.
