Arthropod Chain Gangs

monk writes "Science News references a story in the October 10 Science about Cambrian invertebrates which formed weird permanent chains up to twenty individuals long. 'The discovery of 525-million-year-old fossils belonging to a new species of arthropod shows that these animals formed communal chains never before seen in fossilized invertebrates.' It should be obvious to any Slashdotter of a certain age that this is the true origin of the so called 'centipede' in the eponymous game."
