Leonid Kruglyak and colleagues report high-throughput selective sequencing of a worldwide collection of 200 wild C. elegans strains, providing a comprehensive characterization of genetic variation in this species. They find that chromosome-scale selective sweeps have acted to reduce genetic variation and shape the C. elegans population structure in recent history.
