Abstract
Recent studies show that local populations of the nematode Caenorhabditis elegans possess nearly as much genetic variation as that seen in existing worldwide collections. This suggests either wide-ranging migration and intense natural selection or recent dispersal, perhaps by human association. Either way, the effective population size of this ubiquitous model organism is unexpectedly small.
