Modern zoology recognises not merely the four types of Cuvier, but seventeen different styles, “phyla,” or groups of forms, to derive one of which from another is hopeless. And what is true of the whole is true also of the subdivisions within each phylum; e.g., within the vertebrate phylum with its fishes, amphibians, reptiles, birds and mammals. No bridge leads from one to the other.
The fact that such diverse points of view could direct the observer towards the same result gives, inferentially, a suggestive lesson in what the modern physiologist calls the homologies of parts of the organism. This classification, as will be observed, is not so very far afield from the modern divisions into mammals, birds, reptiles, amphibians, and fishes.
After much shouting and firing of guns, a score of villagers appear on the opposite bank, and several of them come wading and swimming across. They seem veritable amphibians, capable of stemming the tide that well-nigh sweeps strong horses off their feet. The river is fordable by following a zigzag course well known to the local watermen.
Before man the great and prevalent creatures followed one another processionally to extinction; the early monsters of the ancient seas, the clumsy amphibians struggling breathless to the land, the reptiles, the theriomorpha and the dinosaurs, the bat-winged reptiles of the Mesozoic forests, the colossal grotesque first mammals, the giant sloths, the mastodons and mammoths; it is as if some idle dreamer moulded them and broke them and cast them aside, until at last comes man and seizes the creative wrist that would wipe him out of being again.
He stared, mouth open, then yelled: "Roger is here, rebuilding his planetoid! Roger Carries On For gray Roger had not perished in the floods of Nevian energy which had destroyed his planetoid. While those terrific streamers of force emanating from the crimson obscurity surrounding the amphibians' space-ship were driving into his defensive screens, Roger sat impassive and immobile at his desk.
In the next stage they became fishes or reptiles, An-Tak was not positive which, and in this form, always developing, they swam far to the south, where, amid the rank and teeming jungles, some of them evolved into amphibians.
Here we must certainly with shame confess that the amphibians of old greatly surpassed their degenerate descendants in our modern waters. But the reason of this falling off is not far to seek. For a while, therefore, like all dominant races for the time being, they blossomed forth at their ease into relatively gigantic forms.
Then, too, we don't know where to look for what little land there is, and, even if we could find it, we know that it is all over-run with amphibians already. There's a lot of things that might be better, but they might be a lot worse, too. How about it? Do we try it or do we stay here?" "We try it!" exclaimed Clio and Bradley as one. "All right.
But we shall see how obscure this subject is if we look, for instance, to fishes, among which some naturalists rank those as highest which, like the sharks, approach nearest to amphibians; while other naturalists rank the common bony or teleostean fishes as the highest, inasmuch as they are most strictly fish-like, and differ most from the other vertebrate classes.
Even among these back-boned animals we find that the lower groups the fishes, the amphibians, and the reptiles promise little in the way of gains as compared with the higher groups, the birds and mammals; yet even among these inferior creatures we find certain forms which give promise of improvement under the care of man.
