And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good. And God made the beast of the earth after his kind, etc. - Every thing both in the animal and vegetable world was made so according to its kind, both in genus and species, as to produce its own kind through endless generations. Thus the several races of animals and plants have been kept distinct from the foundation of the world to the present day. This is a proof that all future generations of plants and animals have been seminally included in those which God formed in the beginning.
