Chapter VI.
THE TESTIMONY OF THE FLORA AND FAUNA.
Proofs are abundant that there must have been at one time uninterrupted land communication between Europe and America. In the words of a writer upon this subject,
"When the animals and plants of the Old and New World are compared, one cannot but be struck with their identity; all or nearly all belong to the same genera, while many, even of the species, are common to both continents. This is most important in its bearing on our theory, as indicating that they radiated from a common centre after the Glacial Period.… The hairy mammoth, woolly-haired rhinoceros, the Irish elk, the musk-ox, the reindeer, the glutton, the lemming, etc., more or less accompanied this flora, and their remains are always found in the post-glacial deposits of Europe as low down as the South of France. In the New World beds of the same age contain similar remains, indicating that they came from a common centre, and were spread out over both continents alike." (Westminster Review, January, 1872, p. 19.)
Recent discoveries in the fossil beds of the Bad Lands of Nebraska prove that the horse originated in America. Professor Marsh, of Yale College, has identified the several preceding forms from which it was developed, rising, in the course of ages, from a creature not larger than a fox until, by successive steps, it developed into the true horse. How did the wild horse pass from America to Europe and Asia if there was not continuous land communication between the two continents? He seems to have existed in Europe in a wild state prior to his domestication by man.
