When thevariation is such as to adapt it more perfectly to its conditions, thefresh variety will tend to supplant the former.
So far from a gradual progress towards perfection forming any necessarypart of the Darwinian creed, it appears to us that it is perfectlyconsistent with indefinite persistence in one estate, or with a gradualretrogression. Suppose, for example, a return of the glacial epoch anda spread of polar climatal conditions over the whole globe. Theoperation of natural selection u...nder these circumstances would tend, onthe whole, to the weeding out of the higher organisms and thecherishing of the lower forms of life. Cryptogamic vegetation wouldhave the advantage over Phanerogamic; Hydrozoa over Corals; Crustaceaover Insecta, and Amphipoda and Isopoda over the higher Crustacea;Cetaceans and Seals over the Primates; the civilization of theEsquimaux over that of the European.
