Abstract excerpt

Behaviours evolve by iterations of natural selection, but we have few insights into the molecular and neural mechanisms involved. Here we show that some Caenorhabditis elegans wild strains switch between two foraging behaviours in response to subtle changes in ambient oxygen. This finely tuned switch is conferred by a naturally variable hexacoordinated globin, GLB-5. GLB-5 acts with the atypical soluble guanylate...
