In comparing civilized man with the animal world, one is as the Alpine traveller, who sees the mountains soaring into the sky and can hardly discern where the deep shadowed crags and roseate peaks end, and where the clouds of heaven begin. Surely the awe-struck voyager may be excused if, at first, he refuses to believe the geologist, who tells him that these glorious masses are, after all, the hardened mud of primeval seas, or the cooled slag of subterranean furnaces—of one substance with the dullest clay, but raised by inward forces to that place of proud and seemingly inaccessible glory. But the geologist is right; and due reflection on his teachings, instead of diminishing our reverence and our wonder, adds all the force of intellectual sublimity, to the mere aesthetic intuition of the uninstructed beholder.

So long as Geology had not lifted up a part of the veil... it was easy to treat these questions as too transcendental... But it is no longer possible to restrain curiosity from attempting to pry into the relations which connect the present state of the animal and vegetable worlds, as well as of the various races of mankind, with the state of the fauna and flora which immediately preceded.

Imagine trying to identify and compare equivalent bits of anatomy shared between an oyster, a beetle and a blue whale. That is essentially the problem we face with early vertebrate fossils.

The fossil hunter must first of all be a scientific enthusiast. He must be willing to endure all kinds of hardships, to suffer cold in the early spring and the late autumn and early winter months, to suffer intense heat and the glare of the sun in summer months, and he must be prepared to drink alkali water, and in some regions to fight off the attack of the mosquito and other pests. He must be something of an engineer in order to be able to handle large masses of stone and transport them over roadless wastes of desert to the nearest shipping point; he must have a delicate and skilful touch to preserve the least fragments of bone when fractured; he must be content with very plain living, because the profession is seldom, if ever, remunerative, and he is almost invariably underpaid; he must find his chief reward and stimulus in the sense of discovery and in the despatching of specimens to museums which he has never seen for the benefit of a public which has little knowledge or appreciation of the self-sacrifices which the fossil hunter has made.

Geologists discover... an almost complete difference to exist between the species or stamp of life, of one epoch from that of every other. We are therefore led to admit, either of a repeated miraculous creation; or of a power of change, under a change of circumstances, to belong to living organised matter, or rather to the congeries of inferior life, which appears to form superior.

Geology has joined biology in lowering mankind's self-esteem. Geology suggests how mankind's existence is contingent upon the geological consent of the planet.

GEOLOGY, n. The science of the earth's crust — to which, doubtless, will be added that of its interior whenever a man shall come up garrulous out of a well. The geological formations of the globe already noted are catalogued thus: The Primary, or lower one, consists of rocks, bones or mired mules, gas-pipes, miners' tools, antique statues minus the nose, Spanish doubloons and ancestors. The Secondary is largely made up of red worms and moles. The Tertiary comprises railway tracks, patent pavements, grass, snakes, mouldy boots, beer bottles, tomato cans, intoxicated citizens, garbage, anarchists, snap-dogs and fools.

& what we share is the bark, the bones. Paleontologists, from one fossilized femur, Can dream up a species, Make believe a body Where there was none. Our remnants are revelation, Our requiem as raptus. When we bend into dirt We’re truth preserved Without our skin.

Variation and natural selection would also afford a key to a multitude of geological facts otherwise wholly unaccounted for, as, for example, why there is generally an intimate connection between the living animals and plants of each great division of the globe and the extinct fauna and flora of the post-tertiary or tertiary formations of the same region...

It was long ere the distinct nature and legitimate objects of geology were fully recognized, and it was at first confounded with many other branches of inquiry, just as the limits of history, poetry, and mythology were ill-defined in the infancy of civilization. Werner appears to have regarded geology as little other than a subordinate department of mineralogy and Desmarest included it under the head of Physical Geography. ...The first who endeavored to draw a clear line of demarcation between these distinct departments, was Hutton, who declared that geology was in no ways concerned with 'questions as to the origin of things.'

Few men, whatever their creed, would now seek their geology in the books of their religion, or, on the other hand, would fancy that the laboratory or the microscope could help them to penetrate the mysteries which hang over the nature and the destiny of the soul of man. ... We live in a small, bright oasis of knowledge, surrounded on all sides by a vast, unexplored region of impenetrable mystery.

Since the dawn of time, several billion human (or humanlike) beings have lived, each contributing a little genetic variability to the total human stock. Out of this vast number, the whole of our understanding of human prehistory is based on the remains, often exceedingly fragmentary, of perhaps five thousand individuals. You could fit it all into the back of a pickup truck if you didn't mind how much you jumbled everything up, Ian Tattersall, the bearded and friendly curator of anthropology at the American Museum of Natural History in New York, replied when I asked him the size of the total world archive of hominid and early human bones.
The shortage wouldn't be so bad if the bones were distributed evenly through time and space, but of course they are not. They appear randomly, often in the most tantalizing fashion. Homo erectus walked the Earth for well over a million years and inhabited territory from the Atlantic edge of Europe to the Pacific side of China, yet if you brought back to life every Homo erectus individual whose existence we can vouch for, they wouldn't fill a school bus. Homo habilis consists of even less: just two partial skeletons and a number of isolated limb bones. Something as short-lived as our own civilization would almost certainly not be known from the fossil record at all.
In Europe, Tattersall offers by way of illustration, you've got hominid skulls in Georgia dated to about 1.7 million years ago, but then you have a gap of almost a million years before the next remains turn up in Spain, right on the other side of the continent, and then you've got another 300,000-year gap before you get a Homo heidelbergensis in Germany and none of them looks terribly much like any of the others. He smiled. It's from these kinds of fragmentary pieces that you're trying to work out the histories of entire species. It's quite a tall order. We really have very little idea of the relationships between many ancient species which led to us and which were evolut

Geologists claim to find evidence from the earth itself that it is very much older than the Mosaic record teaches. Bones of men and animals, as well as instruments of warfare, petrified trees, et cetera, much larger than any that now exist, or that have existed for thousands of years, have been discovered, and from this it is inferred that the earth was populated long before the time brought to view in the record of creation, and by a race of beings vastly superior in size to any men now living. Such reasoning has led many professed Bible believers to adopt the position that the days of creation were vast, indefinite periods. But apart from Bible history, geology can prove nothing. Those who reason so confidently upon its discoveries have no adequate conception of the size of men, animals, and trees before the Flood, or of the great changes which then took place. Relics found in the earth do give evidence of conditions differing in many respects from the present, but the time when these conditions existed can be learned only from the Inspired Record. In the history of the Flood, inspiration has explained that which geology alone could never fathom. In the days of Noah, men, animals, and trees, many times larger than now exist, were buried, and thus preserved as an evidence to later generations that the antediluvians perished by a flood. God designed that the discovery of these things should establish faith in inspired history; but men, with their vain reasoning, fall into the same error as did the people before the Flood — the things which God gave them as a benefit, they turn into a curse by making a wrong use of them.

Geology... possesses the great advantage of presenting subjects adapted to every capacity; on some of its investigations the highest intellectual powers and the most profound acquirements in exact science are required; while many of its problems may be solved by any one who has eyes and will use them; and innumerable facts illustrative of the ancient condition of our planet, and of its inhabitants, may be gathered by any diligent and intelligent observer.
