Cosmo might have had lions and tigers, and similar beasts, which had been preserved, in larger numbers than the useful horse, but when Joseph Smith suggested their inclusion he shook his head, declaring that it was better that they should perish. As far as possible, he averred, he would eliminate all carnivores.
That assuredly is not the effect of an invasion of carnivores, even if we could overlook the absence of such carnivores from the record until after the extinction of the reptiles in most places.
Linnaeus led the way in this field of inquiry by comparing Man and the apes, in the same manner as he compared these last with the carnivores, ruminants, rodents, or any other division of warm-blooded quadrupeds.
But the rising carnivores, the falls of temperature, etc., that we have studied, have had so real, if indirect, an influence on the development of life that we need not dwell on this. Another school, or several schools, while admitting the action of natural selection, maintain that earlier evolutionists have made nature much too red in tooth and claw. Dr.
From this summary review of the evolution of the Ungulates we must now pass to an even briefer account of the evolution of the Carnivores. The evidence is less abundant, but the characters of the Carnivores consist so obviously of adaptations to their habits and diet that we have little difficulty in imagining their evolution.
when I risked myself, with many misgivings, in little-tried paths of what looked at first like a wilderness, a selva oscura, where, if I did not meet the lion or the wolf, I should be sure to find the critic, the most dangerous of the carnivores, waiting to welcome me after his own fashion. The second Portfolio is closed and laid away.
He came to the place where the creature should be. There was silence. He flicked the flint of his pocket lighter and in the flash of brightness he saw his prey. It had heard his approach. It was a porcupine, prudently curled up into a spiky ball and placidly defying all carnivores, including men. A porcupine is normally the one wild creature without an enemy.
It was probably evolved in the Post-Tertiary Era, about twenty million years ago, when the coming of the carnivores introduced direct body-to-body conflicts, and their concomitants, a quick and versatile nervous system. During the Tertiary epoch the earth basked in the heat of a tropical sun nearly everywhere on its surface.
The regularity and evenness of the dentition of the Anoplotherium, as contrasted with that of existing Artiodactyles, and the assumed nearer approach of the dentition of certain ancient Carnivores to the typical arrangement, have also been cited as exemplifications of a law of progressive development, but I know of no other cases based on positive evidence which are worthy of particular notice.
In their struggle for existence in a country subject to sudden great changes of temperature, to drought, and failure of grass, they have in a great measure lost the qualities which make the sheep valuable to man as a food and wool-producing animal; but on the other hand they have to some extent recovered the vigour of a wild animal, being hardy enough to exist without any shelter, and requiring from their master man only protection from the larger carnivores.
