They incline us to view favorably the idea of transmutations of one form into another, rather than that of sudden creations.
Creation implies an abrupt appearance, transformation a gradual change.
In this manner is presented to our contemplation the great theory of Evolution.

Every organic being has a place in a chain of events.

It is not an isolated, a capricious fact, but an unavoidable phenomenon.

It has its place in that vast, orderly concourse which has successively risen in the past, has introduced the present, and is preparing the way for a predestined future.

From point to point in this vast progression there has been a gradual, a definite, a continuous unfolding, a resistless order of evolution.
