"Some species of the nematode worm (Caenorhabditis elegans) are sociable
diners, clumping together to share a meal, yet others are more solitary.
Why? According to a report by de Bono and Bargmann (Cell 94,679-689;1998),
these differences can be explained by a change of just one amino acid in a
putative neuropeptide receptor." Allison Mitchell, "Worming out Social
Secrets," Nature, 395(1998):327
