(19) When we talk of first appearance, we mean the discovery of
remains. All who believe in the doctrine of evolution, know that
the class Mammalia must have appeared early in Paleozoic times.
Thus, Mr. Wallace says, "Bats and whales--strange modifications
of mammals--appear perfectly well developed in the Eocene.
What countless ages back must we go for the origin of these
groups--the whales from some ancestral carnivorous animal, the
bats from the insectivora!" and even then we have to seek for
the common origin of these groups at far earlier periods.
"So that, on the lowest estimate, we must place the origin of
the Mammalia very far back in Paleozoic times." ("Island Life,"
p. 201.)
