If you doubt it, here is the latest deliverance of infallible science upon the subject.

He describes the Ascidians: "They hardly appear like animals, and consist of a simple tough leathery sack, with two small projecting orifices.

They belong to the Molluscoida of Huxley, a lower division of the great family of the Mollusca; but they have recently been placed by some naturalists among the vermes or worms.
Their larvae somewhat resemble tadpoles in shape, and have the power of swimming freely about.

* * * We should thus be justified in believing that, at an extremely remote period, a group of animals existed resembling in many respects the larvae of our present Ascidians, which diverged into two great branches, the one retrograding in development and producing the present class of Ascidians, the other rising to the crown and summit of the animal kingdom, by giving birth to the vertebrata."[8] Thus it appears that Mr.Darwin deduces his origin, and that of mankind in general, from one of these Ascidians, or, in plain English, makes them a race of squirts.
The notion of evolution is a belief that all living beings, plants as well as animals, have not been created, but, like Topsy, just grew, from the very smallest germs or spores.

Evolutionists inform us that all kinds of organisms have been evolved from four or five primeval germs or spores; or more consistently with their great principle, that the simple gave birth to the differentiated, from one primeval germ or egg.
