Evolution and development: anchors away!
Developmental mechanisms can evolve even when the trait they produce does not, and the nematode vulva has become a model organ for detecting such "developmental system drift". A new study reveals what may be the very earliest stages of this process by experimentally modifying key vulval signaling pathways in different species of Caenorhabditis, and carefully quantifying the results.
