Caption: A living arthropod (centipede Cormocephalus) crawls over its 515-million-year-old relative which lived during the Cambrian explosion (trilobite Estaingia). A study of arthropods reveals that their anatomy and genes evolved five times faster during evolution's Big Bang, compared to all subsequent periods -- fast, but totally compatible with Darwin's theory. Both the centipede and trilobite are found on what is now Kangaroo Island, Australia.
