mentioned only to be dismissed. It was formerly assumed that the human ancestor was probably arboreal, but the current idea among those who are qualified to form an opinion seems to be that he was a ground ape, and that the existing apes have developed in the arboreal direction.

 

Of course if one puts the skeleton of a man and the skeleton of a gorilla side by side, their general resemblance is so great that it is easy to jump to the conclusion that the former is derived from such a type as the latter by a process of brain growth and general refinement. But if one examines closely into one or two differences, the gap widens. Particular stress has recently been laid uponthe tread of the foot. Man walks

on his toe and his heel; his great toe is his chief lever in walking, as the reader may see for himself if he examines his own footprints on the bathroom floor and notes where the pressure falls as the footprints become fainter. His great toe is the king of his toes.

Among all the apes and monkeys, the only group that have theirgreat toes developed on anything like the same fashion as man are some of the lemurs. The baboon walks on a flat foot and all his toes, using his middle toe as his chief throw-off, much as the bear does. And the three great apes all walk on the outer side of the foot in a very different manner from the walking of man.

 

The great apes are forest dwellers; their walking even now is incidental; they are at their happiest among trees. They have very distinctive methods of climbing; they swing by the arms much more than the monkeys do, and do not, like the latter, take off with a spring from the feet. They have a specially developed climbing style of their own. But man walks so well and runssoswiftly as to suggest a very long ancestry upon the ground. Also, he does not climb well now; he climbs with caution and hesitation. His ancestors may have been running creatures for long ages. Moreover, it is to be noted that he does not swim naturally; he has to learn to swim, and that seems to point to a long-standing separation from rivers and lakes and the sea. Almost certainly that ancestor was a smaller and slighter creature than its human descendants. Conceivably the human ancestor at the opening of the Cainozoic. period was a running ape living chiefly on the ground, hiding among rocks rather than trees. It could still climb trees well and hold things between its great toe and its second toe (as the Japanese can to this day), but it was already coming down to the ground again from a still remoter, a Mesozoic arboreal ancestry. It is quite understandable that such a creature would very rarely die in water in such circumstances as to leave bones to become fossilized.

It must always be borne in mind that among its many other imperfections the Geological Record necessarily contains abundant traces only of water or marsh creatures or of creatures easily and frequently drowned. The same reasons that make any traces of the ancestors of the mammals rare and relatively unprocurable in the Mesozoic rocks, probably make the traces of possible human ancestors rare and relatively unprocurable in the Cainozoic rocks. Such knowledge as we have of the earliest men, for example, is almost entirely got from a few eaves, into which they went and in which they left their traces. Until the hard Pleistocene times they lived and died in the open, and their bodies were consumed or decayed altogether.

 

But it is well to bear in mind also that the record of the rocks has still to be thoroughly examined. It has been studied only for a few generations, and by only a few men in each generation. Most men have been too busy making war, making profits out of their neighbours, toiling at work that machinery could do for them in a tenth of the time, or simply playing about, to give any attention to these more interesting things. There may be, there probably are, thousands of deposits still untouched containing countless fragments and vestiges of man and his progenitors. In Asia particularly, in India or the East Indies, there may be hidden the most illuminating clues. What we know to-day of early men is the merest scrap of what will presently be known.

 

The apes and monkeys already appear to have been differentiated at the beginning of the Cainozoic Age, and there are a number of Oligocene and Miocene apes whose relations to one another and to the human line have still to be made out. Among these we may mention Dryopithecus of the Miocene Age, with a very human-looking jaw. In the Siwalik Hills of northern India remains of some very interesting apes have been found, of which Sivapithecus and Palaeopithecus were possibly related closely to the human ancestor. Possibly these animals already used implements. Charles Darwin represents baboons as opening nuts by breaking them with stones, using stakes to prise up rocks in the hunt for insects, and striking blows with sticks and stones. The chimpanzee makes itself a sort of tree hut by intertwining branches. Stones apparently chipped for use have been found in strata of Oligocene Age at Boncelles in Belgium. Possibly the implement-using disposition was already present in the Mesozoic ancestry from which we are descended.

 

7.2 First Traces of Man-like Creatures

 

Among the earliest evidences of some creature, either human or at least more manlike than any living ape upon earth, are a number of flints and stones very roughly chipped and shaped so as to be held in the hand. These were probably used as handaxes. These early implements (Eoliths) are often so crude and simple that there was for a long time a controversy whether they were to be regarded as natural or artificial productions. The date of the earliest of them is put by geologists as Pliocene"that is to say, before the First Glacial Age. They occur also throughout the First Interglacial period. We know of no bones or other remains in Europe or America of the quasi-human beings of half a million years ago, who made and used these implements. They used them to hammer with, perhaps they used them to fight with, and perhaps they used bits of wood for similar purposes. [1]

 

But at Trinil, in Java, in strata which are said to correspond either to the later Pliocene or to the American and European First Ice Age, there have been found some scattered bones of a creature, such as the makers of these early implements may have been. The top of a skull, some teeth, and a thigh-bone have been found. The skull shows a brain-case about half-way in size between that of the chimpanzee and man, but the thigh-bone is that of a creature as well adapted to standing and running as a man, and as free, therefore, to use its hands. The creature was not a man, nor was it an arboreal ape like the chimpanzee. It was a walking ape. It has been named by naturalists Pithecanthropus erectus (the walking ape-man). We cannot say that it is a direct human ancestor, but we may guess that the creatures who scattered these first stone toolsover the world must have been closelysimilar and kindred, and that ourancestor was a beast of like kind. This little trayful of bony fragments from Trinil is, at present, apart from stone implements, the oldest relic of early humanity, or of the close blood relations of early humanity, that is known.

 

While these early men or sub-men were running about Europe four or five hundred thousand years ago, there were mammoths, rhinoceroses, a huge hippopotamus, a giant beaver, and a bison and wild cattle in their world. There were also wild horses, and the sabre-toothed tiger still abounded. There are no traces of lions or true tigers at that time in Europe, but there were bears, otters, wolves, and a wild boar, it may be that the early sub-man sometimes played jackal to the sabre-toothed tiger, and finished up the bodies on which the latter had gorged itself.

 

7.3 The Heidelberg Sub-Man

 

After this first glimpse of something at least sub-human in the record of geology, there is not another fragment of human or man-like bone yet known from that record for an interval of hundreds of thousands of years. It is not until we reach deposits which are stated to be of the Second Interglacial period, 200,000 years later, 200,000 or 250,000 years ago, that another little scrap of bone comes to hand. Then we find a jaw-bone.

 

This jaw-bone was found in a sand-pit near Heidelberg, at a depth of eighty feet from the surface, and it is not the jawbone of a man as we understand man, but it is man-like in every respect, except that it has absolutely no trace of a chin; it is more massive than a man's, and its narrowness behind could not, it is thought, have given the tongue sufficient play for articulate speech. It is not an ape's jaw-bone; the teeth are human. The owner of this jaw-bone, has been variously named Homo Heidelbergensis and Paleoanthropus Heidelbergensis, according to the estimate formed of his humanity or sub-humanity by various authorities. He lived in a world not remotely unlike the world of the still earlier sub- man of the first implements; the deposits in which it is found show that there were elephants, horses, rhinoceroses, bison, a moose, and so forth with it in the world, but the sabre-toothed tiger was declining and the lion was spreading over Europe. The implements of this period (known as the Chellean period) are a very considerable advance upon those of the Pliocene Age. They are well made butvery much bigger than any truly human implements. The Heidelberg man may have had a very big body and large fore limbs. He may have been a woolly, strange-looking creature.

 

7.4 The Piltdown Sub-Man

 

We must turn over the Record for, it may be, another 100,000 years for the next remains of anything human or sub-human. Then in a deposit ascribed to the Third Interglacial period, which may have begun 100,000 years ago and lasted 50,000 years, the smashed pieces of a whole skull turn up. The deposit is a gravel which may have been derived from the washing out of still earlier gravel strata, and this skull fragment may be in reality as old as the First Glacial Period. The bony remains discovered at Piltdown in Sussex display a creature still ascending only very gradually from the sub-human.

 

The first scraps of this skull were found in an excavation for road gravel in Sussex. Bit by bit other fragments of this skull were hunted out from the quarry heaps until most of it could be pieced together. It is a thick skull, thicker than that of any living race of men, and. it has a brain capacity intermediate between that of Pithecanthropus and man. This creature has been named Eoanthropus, the dawn man. In the same gravel-pits were found teeth of rhinoceros, hippopotamus, and the leg-bone of a deer with marks upon it that may be cuts. A curious bat-shaped
