Document Summary

Anatomical, molecular, and fossil evidence: make sure you know the key derived characteristics that define the clades in chordates. (see figure. Lancelets, tunicates, hagfish, lampreys, sharks and rays, ray-finned fishes, lobe-fish, amphibians, 3 head, 4 vertebral column, 5 jaws, 6 lungs or lung derivatives, 7 lobed fins, 8 legs, 9 amniotic eggs, 10 milk. 1-2 chordates, 3 craniate, 4 vertebrates, 5-7 jawed vertebrate, 8 tetrapod, 9-10 amniotes: define the following: craniate, tetrapod, amniotes, vertebrates. Tetrapod: jawed vertebrate with two pairs of limbs. Amniotes: tetrapod with eggs adapted for life on land. Vertebrates: more extensive skull and backbone/vertebral column: _________ are thought to be the first animals to branch from the chordate lineage. Lancelet: __________ and ______ are the most primitive craniate. Hagfish: deep-sea scavengers that use slime as defense. Gas exchange, water conservation, structural support, locomotion, sensory organs, reproduction: the first vertebrates able to colonize the land are the ____________.
