Palæarctic

Portrait of Alfred Russel Wallace Alfred Russel Wallace The Geographical Distribution of Animals…

The Palæarctic element, however, forms so small apportion of the whole fauna, that it may be satisfactorily accounted for by the establishment of immigrants since the Glacial period. The great interest felt by ornithologists in the discovery of the three genera above-named, with a wren allied to a European species, is an indication that the faunas even of the northern parts of the Nearctic and Palæarctic regions are, as regards birds, radically distinct.

Hans Gadow The Cambridge natural history, Vol… (1909)

The Urodela thus lend no support to the usual division of the Periarctic into a Palaearctic and a Nearctic sub-region. Nor is it possible to divide the Palaearctic into a Eurasian and a Mediterranean province. We have in this case to distinguish between an American, an Asiatic, and a European fauna. The Asiatic or Eastern Palaearctic sub-region assumes the central position, at least from a merely geographical point of view. It would be unjustifiable to assume a spreading from this centre into Europe, and, on the other hand, into America.

editor W.L. Distant The Zoologist (1899)

Many zoologists have advocated the union of the Palæarctic and Nearctic regions from the similarity, or rather the many similarities, to be found in their faunas, but the Sclaters argue that these affinities are only of recent origin, and that "palæontological evidence seems to show that, out of all the four regions embraced under the term 'Arctogœa,' [1] the North American or Nearctic Region was the first to be separated from the main mass, and that the similarity is a comparatively modern element in the character of the two faunas."
