These are candidates for genes specific to chordates," says Rokhsar. The series will devote hour-long programs to eight of the major body plans--sponges, cnidarians (jellyfish and kin), flatworms, mollusks, annelids (earthworms) arthropods (insects, spiders, lobsters), echinoderms (starfish, sea urchins) and chordates (fish, birds, humans). The earliest chordates presumably resembled amphioxus in being nearly brainless animals that lacked paired eyes and fed by filtering food from the water. |
