The enduring challenge of the human fossil record: Why scarcity fuels skepticism

“ Humanity has always been so much less populous than the remainder of the animal kingdom, especially in its earlier stages, that the number of individuals whose bones have been preserved as fossils is infinitely smaller. The result is that we account ourselves fortunate in having been able to assemble six or seven not quite complete skeletons, and fragmentary portions of two or three dozen other individuals, of the Neandertal race which inhabited western Europe for thousands of years. For still earlier races or species of man the actual data are even scantier. ”

“ That the record is really imperfect is not a matter which admits of controversy. No one supposes that every species and variety that ever existed in past ages on the globe is represented at this very day by fossil specimens in prime enough condition to exhibit all the characteristics of the creature as it once lived. No one supposes that, if such specimens existed, all of them ever could or would be found by human beings. It is not in the nature of a fossil to present all the characteristics of the creature as it once lived. It cannot possibly do it; for the fossil is without life and motion. ”

“ The imperfectness of the geological record is certainly a great hindrance to the exact proof of the Darwinian theory, and is a strong weapon in the hands of its opponents. But while so much of the dim, remote past is attainable only by inference and deduction, the argument is decisive for neither side. One weighty argument for the Darwinians is the general plan upon which animals are constructed. All vertebrates have the same typical form. Take off the skins from some dozen air-breathing vertebrates, place the bodies in an upright attitude, and they are in general structure identical. ”

“ The entire absence of human remains during the 750,000 years and more is a demonstration against the brute origin of man, and a proof of special creation.
It will be remembered that there is no complete skeleton among all the remains, nor enough parts to make one altogether, nor to make any large part of a skeleton,—not even an entire skull. What bones are found are not joined together, and some of them scattered so widely apart, that no one can be certain they belong to the same individual. Some of the bones belong to an ape, and some to man,—doubtless modern man. ”

“ Not one skull is to be found entire; and it is so rare to find a large bone of any kind that has not been more or less broken, that there is no hope of obtaining materials for the construction of a single limb, and still less of an entire skeleton. ”

“ Yet in these same formations there is no want of bones of mammalia belonging to extinct and living species. In the course of the last quarter of a century, thousands of them have been submitted to the examination of skilful osteologists, and they have been unable to detect among them one fragment of a human skeleton, not even a tooth. ”

“ The remains of man are nowhere found in the strata which contain the records of former states of the earth. Skeletons of vast varieties of creatures have been disinterred from their rocky tombs; but these cemeteries of nature supply no portion of a human skeleton. In earlier periods of natural science, when comparative anatomy was as yet very imperfectly understood, no doubt, many fossil bones were supposed to be human bones. ”

“ It is well known that a competent naturalist needs but a single fossil bone to describe the animal itself, and tell us its habits. So also anthropologists need but fragments of the human skeleton, especially of the skull, to describe characteristics of the race to which the individual belonged.
This cut, though an ideal restoration, is a restoration made in accordance with the results of careful study of fragmentary skulls found in various localities in Europe. The head and the face present a savage aspect; the body harmonized with the head; the height was not more than five feet and a half ”

“ This law prevails, no less universally, throughout the existing kingdoms of animated nature, than in those various races of extinct creatures that have preceded the present tenants of our planet; hence not only the framework of, the fossil skeleton of an extinct animal, but also the character of the muscles, by which each bone was moved, the external form and figure of the body, the food, and habits, and haunts, and mode of life of creatures that ceased to exist before the creation of the human race, can with a high degree of probability be ascertained. ”

“ Unquestionably ancient as these remains are,—the bones are completely fossilized,—they contained lamentably few "primitive characteristics," and hence have not been exploited in the interest of the evolutionary theory. A fragment of skull, a tooth, a thigh-bone, offer much more inviting fields to the evolutionists, since they permit his imagination to range without the restraint of fact. The Oldoway fossil, which is in every essential respect a normal human skeleton, possesses no special attractions for those who would represent man as a descendant of brutish ancestors. ”

“ On this doctrine of the extermination of an infinitude of connecting links between the living and extinct inhabitants of the world, and at each successive period between the extinct and still older species, why is not every geological formation charged with such links? Why does not every collection of fossil remains afford plain evidence of the gradation and mutation of the forms of life? We meet with no such evidence, and this is the most obvious and plausible of the many objections which may be urged against my theory. ”

“ It is absurd to rank man among the animals. His so called fellow animals, the primates—gorilla, orang and chimpanzee—can do nothing truly human.”
Sir William Dawson, an eminent geologist, of Canada, said: “The record of the rocks is decidedly against evolutionists, especially in the abrupt appearance of new forms under specific types, and without apparent predecessors.... Paleontology furnishes no evidence as to the actual transformation of one species into another. No such case is certainly known. Nothing is known about the origin of man except what is told in Scripture.” ”

“ It is so very rare an instance to meet in fossile remains with a real human bone, skull, jaw-bone or entire human skeleton (as in one particular instance was found enclosed in a lime-stone, mixed with some few utensils and instruments of the primitive world, such as a stone-knife, a copper axe, an iron club, and a dagger of a very ancient form, together with some human bones) ; that the very rareness of the exception serves only to confirm the general rule. ”

“ The explanation of this state of things is not at all difficult, for it is only under very rare circumstances that portions of the bones of animals even larger than man are preserved to us in geological strata. Vast numbers die and vanish away without leaving a trace behind them for every fragmentary bone we recover. In the case of man we must remember that, in previous eras, he was present in very small numbers; that, owing to his intelligence, he would not be as liable to be drowned and swept away, and so mingle his remains with beds of river detritus then forming, as were animals. ”

“ In the third place, man belongs to the class of animals least likely to be preserved in the fossil state, since they dwell in the depths of forests and at a distance from the lakes and streams in whose muddy bottoms the remains of so many [131] animals have been fossilized. Another answer is, that of the various species of anthropoid apes that probably existed in the past, a few relics only of a single species have been found. If there were this one species alone, its number of individuals must have reached into the millions, yet of those hosts only a few fugitive bones are known to exist. ”

“ Sound and well-preserved skeletons, known to be nearly two thousand years old, have been taken from burial-places in England, and other European countries less favorable for preserving them. The condition of an ancient skeleton can not be used as an accurate measure of time, but it is sufficiently accurate to show the difference between the ancient and the modern, and in this case it allows us to assume that these extremely decayed skeletons of the Mound-Builders are much more than two thousand years old. ”

“ In general, it may be said that the higher the geological antiquity of a skeleton is, the greater is the chemical alteration which it has undergone. Bones of Pleistocene or later date have, as a rule, suffered little change beyond the loss of more or less of their animal matter, the amount of such loss depending chiefly upon exposure to the air. Bones which, for thousands or tens of thousands of years, have been buried in dense cave-earth, in an antiseptic peat-bog, or in asphalt, are often perfectly sound and fresh when taken up. ”

“ In making the division of Vertebrate animals into classes the skeleton is often almost ignored. Its value is entirely empirical and based upon the observed association of the various forms of bones with the more important characters of the brain and other vital organs. What is understood as a Mammalian or Avian character in the skeleton is the form of bone which is found in association with the soft vital organs which constitute an animal a Mammal or a Bird. ”

“ I will therefore briefly state how reptiles are defined in some regions of the skeleton, for in tracing the history of reptile life the bones are the principal remains of animals preserved in the rocks; and the soft organs which have perished can only be inferred to have been present from the persistence of durable characteristic parts of the skeleton, which are associated with those soft organs in animals which exist at the present day, and are unknown in other animals in which the skeleton is different. ”

“ But to return from this digression to the objections against the Pithecanthropus erectus, it must now be explained that the very contrast between the thigh-bone and the skull-cap in respect of these inferences, has been used as an argument against the association of these bones as part of one skeleton.
The objection may be met in two ways at least. For instance, the thigh-bone may yet possess characters which lessen its resemblance to those of recent men, but are not recognised on a superficial inspection. ”

“ Not many years ago bony remains of a human skeleton, or at least of some form very near to modern Man, were found in the Diluvial deposits of Java, and this has been designated Pithecanthropus erectus, and perhaps rightly regarded as a transition form between Apes and Man. It is possible that more may yet be discovered; but even if that is not so, the conclusion that Man had his origin from animal forefathers must be regarded as inevitable and fully established. ”

“ Every one practically acquainted with paleontology is aware that it is not every tooth nor every bone which enables us to form a judgment of the character of the animal to which it belonged, and that it is possible to possess many teeth, and even a large portion of the skeleton of an extinct animal, and yet be unable to reconstruct its skull or its limbs. It is only when the tooth or bone presents peculiarities which Ave know by previous experience to be characteristic of a certain group that we can safely predict that the fossil belonged to an animal of the same group. ”

“ If a newly discovered fossil is widely different from the corresponding parts of any creature previously known, whether living or extinct, we cannot infer very much from a few bones as to what the remainder of the skeleton is like. Such inferences or guesses in the past have often resulted in grievous error, and self-respecting paleontologists are now very reluctant to speculate much concerning extinct animals from fragments of a skeleton, no matter what those fragments or bones may be; future discoveries are sure to reveal errors. ”

“ Sometimes, in problems of this kind, which involve comparison of the details of the skeleton in different animals, it is convenient to imagine the possibility of changes and transitions which are not yet supported by the discovery of fossil remains. ”

“ No doubt most people feel justified in believing that the whole doctrine of evolution must stand or fall according to the cogency of the palæontological evidences. Plain common sense says that the owners of shelly or bony fragments found in the deeply-laid strata of the earth must have lived countless years ago, and if the evolutionist asserts that primitive organic forms of ancient times have produced changed descendants of later times, it would seem that fossil evidence would be supremely and overwhelmingly important. ”

“ A. Up to a certain point, the evidence is strikingly favourable to the hypothesis of human evolution. By this is meant the gradual development of the modern type of skeleton found in association with a large and active brain, capable of manifesting its activity in a great variety of ways. Most of the oldest human skeletons just described, differ from this type. Although a difference cannot be demonstrated in respect of cranial capacity, yet those older skeletons are usually distinguished by the heavier jaw and by stout curved limb-bones of such length as to indicate an almost dwarf stature. ”

“ So far from palaeontology lending no support to the doctrine of evolution—as one sees constantly asserted—that doctrine, if it had no other support, would have been irresistibly forced upon us by the palaeontological discoveries of the last twenty years.
If, however, the diverse forms of life which now exist have been produced by the modification of previously-existing less divergent forms, the recent and extinct species, taken as a whole, must fall into series which must converge as we go back in time. ”

“ The grand fact that all extinct organic beings belong to the same system with recent beings, falling either into the same or into intermediate groups, follows from the living and the extinct being the offspring of common parents. As the groups which have descended from an ancient progenitor have generally diverged in character, the progenitor with its early descendants will often be intermediate in character in comparison with its later descendants; and thus we can see why the more ancient a fossil is, the oftener it stands in some degree intermediate between existing and allied groups. ”

“ The great break in the organic chain between man and his nearest allies, which cannot be bridged over by any extinct or living species, has often been advanced as a grave objection to the belief that man is descended from some lower form; but this objection will not appear of much weight to those who, from general reasons, believe in the general principle of evolution. Breaks often occur in all parts of the series, some being wide, sharp and defined, others less so in various degrees; ”

“ Unfortunately the skull of the only perfect skeleton is said to have been of fair proportions and superior to those of the ruder types of post-Glacial men. This has cast a shade of suspicion on the discovery, especially on the part of evolutionists, who think it is not in accordance with theory that man should retrograde between the Pliocene and the early modern period instead of advancing. ”

“ Lastly, looking not to any one time, but to all time, if my theory be true, numberless intermediate varieties, linking most closely all the species of the same group together, must assuredly have existed; but the very process of natural selection constantly tends, as has been so often remarked, to exterminate the parent forms and the intermediate links. Consequently evidence of their former existence could be found only amongst fossil remains, which are preserved, as we shall in a future chapter attempt to show, in an extremely imperfect and intermittent record. ”

“ The break will then be rendered wider, for it will intervene between man in a more civilised state, as we may hope, than the Caucasian, and some ape as low as a baboon, instead of as at present between the negro or Australian and the gorilla.
With respect to the absence of fossil remains, serving to connect man with his ape-like progenitors, no one will lay much stress on this fact, who will read Sir C. Lyell’s discussion,271 in which he shews that in all the vertebrate classes the discovery of fossil remains has been an extremely slow and fortuitous process. ”
