Evolution; its nature, its evidences, and its relation to religious thought . -A, brain of extinct Ichthyornis;B, modern tern. 170 EVIDENCES OF THE TRUTH OF Fig. 58.—a, brain of Eocene dinoceras ; b, Miocene brontothere; c, modera horse. PROOFS FROM EMBRYOLOGY. 171 Cephalization.—Thus, in going up the phylogenic,the taxonomic, or the ontogenic series, we find a gradualprocess of development headward, brainward, cerebrum-ward ; or, more generally, we might say that in all or-ganic evolution we find an increasing dominance of thehigher over the lower, and of the highest over all. Forexample, in the lowest plane of either series we find firstthe different systems imperfectly or not at all differen-tiated. Then, as differentiation of these progress, wefind an increased dominance of the highest system—thenervous system; then in the nervous system, the in-creasing dominance of its highest part—the brain;then in the brain the increasing dominance of its high-est ganglion—the cerebrum; and, lastly, in the cere-brum the increasing dominance of its highest sub-stance—the exterior gray matter—as shown by the in-creasing number and dept
