animals with rods along their backs, including reptiles, amphibians, birds, and
mammals.
chromatid:
homologous chromosomes joined to each other at the

prophase of
mitosis.
chromatin: compacted
DNA and
protein.

evolutionary trends occur in
chordates:
spinal cord, continuation of
cephalization in the form of larger and more complex brains, and development of a more elaborate
nervous system.
