Evolution: Deep-sea spiral fantasies
John Gage1
Abstract
Pictures of strange, gelatinous deep-sea worms have intrigued zoologists, as they hinted at the solution to an evolutionary puzzle. But does the first specimen to be obtained in good condition back the theories up?
Zoologists dream of connecting up the evolutionary pathways among the ragbag of phyla that have been placed together in the super-phylum Deuterostomia1. This super-phylum includes the chordates — back-boned animals such as ourselves — and the hemichordates ('half chordates'), which are mostly small, bottom-living marine organisms.
