Examples of Diversity
Some of the American plants and animals attracted great attention in Europe when they were first made known there, being recognized as entirely new, and found to be quite peculiar in character. The potato was one; the turkey was another. No turkey was ever known to exist in Europe, Asia, or Africa before that time, and no fossil remains of such an animal have ever been discovered there. The tobacco plant was another species that was originally first found in America, though it has since become extensively diffused throughout the world. A more particular account of some of these plants and animals will be given in future chapter. They are only mentioned here as illustrations of the great truth, that when this country was first explored by European visitors an entirely new series of forms of vegetable and animal life was found to prevail here, and such as could not have resulted from any of the forms that prevail in the old world, within the period of six thousand years, through the operation of any laws that are known to us, in respect to the relation of parent and offspring.
The General Types the Same
And yet, though the plants and animals that are found in America are all different, and seem to be essentially different, so far as relates to derivation from the same parentage within any moderate period, from those of the old world, it is a very curious and a very significant fact, that there is a very close analogy between the two great stocks - an analogy so close as to furnish very strong reason to believe that they must have had a common origin, or at least have derived their existence from some common law. All, or nearly all, the great types of animal and vegetable life which are known in the old world, have their representatives in the new, and yet no particular species are so represented. While there is a generic similarity, there is also a specific difference. We scarcely knew which excites most our wonder and curiosity, the analogy in the great types, or the total, or almost total diversity in individual species.
