<p>Naturalists divide the class <i>Mammalia</i> into a number of orders. At the
head of these is the order <i>Primates</i>, which includes the lemurs, the
monkeys, apes and man. Their classification was based originally upon
anatomical resemblances and took no account of any mental qualities.</p>
<p>Now the past history of the Primates is one very difficult to
decipher in the geological record. They are for the most
part animals which live in forests like the lemurs and
monkeys or in bare rocky places like the baboons. They are
rarely drowned and covered up by sediment, nor are most of
them very numerous species, and so they do not figure so
largely among the fossils as the ancestors of the horses,
camels and so forth do. But we know that quite early in the
Cainozoic period, that is to say some forty million years ago
or so, primitive monkeys and lemuroid creatures had appeared,
poorer in brain and not so specialized as their later
successors.</p>
<p>The great world summer of the middle Cainozoic period drew at
last to an end. It was to follow those other two great
summers in the history of life, the summer of the Coal Swamps
and the vast summer of the Age of Reptiles. Once more the
earth spun towards an ice age. The world chilled, grew
milder for a time and chilled again. In the warm past
hippopotami had wallowed through a lush sub-tropical
vegetation, and a tremendous tiger with fangs like sabres,
the sabre-toothed tiger, had hunted its prey where now the
journalists of Fleet Street go to and fro. Now came a
bleaker age and still bleaker ages. A great weeding and
extinction of species occurred. A woolly rhinoceros, adapted
to a cold climate, and the mammoth, a big woolly cousin of
the elephants, the Arctic musk ox and the reindeer passed
across the scene. Then century by century the Arctic ice
cap, the wintry death of the great Ice Age, crept <span class="pagenum"><SPAN name="P44"></SPAN></span>southward. In
England it came almost down to the Thames, in America it
reached Ohio. There would be warmer spells of a few thousand
years and relapses towards a bitterer cold.</p>
<p>Geologists talk of these wintry phases as the First, Second,
Third and Fourth Glacial Ages, and of the interludes as
Interglacial periods. We live to-day in a world that is
still impoverished and scarred by that terrible winter. The
First Glacial Age was coming on 600,000 years ago; the Fourth
Glacial Age reached its bitterest some fifty thousand years
ago. And it was amidst the snows of this long universal
winter that the first man-like beings lived upon our planet.</p>

<p>By the middle Cainozoic period there have appeared various
apes with many quasi-human attributes of the jaws and leg
bones, but it is only as we approach these Glacial Ages that
we find traces of creatures that we can speak of as
“almost human.” These traces are not bones but
implements. In Europe, in deposits of this period, between
half a million and a million years old, we find flints <span class="pagenum"><SPAN name="P45"></SPAN></span>and stones that
have evidently been chipped intentionally by some handy
creature desirous of hammering, scraping or fighting with the
sharpened edge. These things have been called
“Eoliths” (dawn stones). In Europe there are no
bones nor other remains of the creature which made these
objects, simply the objects themselves. For all the
certainty we have it may have been some entirely un-human but
intelligent monkey. But at Trinil in Java, in accumulations
of this age, a piece of a skull and various teeth and bones
have been found of a sort of ape man, with a brain case
bigger than that of any living apes, which seems to have
walked erect. This creature is now called <i>Pithecanthropus
erectus</i>, the walking ape man, and the little trayful of
its bones is the only help our imaginations have as yet in
figuring to, ourselves the makers of the Eoliths.</p>

<p>It is not until we come to sands that are almost a quarter of
a million years old that we find any other particle of a sub-
human being. But there are plenty of implements, and they
are steadily improving in quality as we read on through the
record. They are no longer clumsy Eoliths; they are now
shapely instruments made with considerable skill. <i>And
they are much bigger than the similar implements afterwards
made by true man.</i> Then, in a sandpit at Heidelberg,
appears a single quasi-human jaw-bone, a clumsy jaw-bone,
absolutely chinless, far heavier than a true human jaw-bone
and narrower, so that it is improbable the creature’s
tongue could have moved about for articulate speech. On the
strength of this jaw-bone, scientific men suppose this
creature to have been a heavy, almost human monster, possibly
with huge limbs and hands, possibly with a thick felt of
hair, and they call it the Heidelberg Man.

<p>This jaw-bone is, I think, one of the most tormenting objects in the
world to our human curiosity. To see it is like looking
through a defective glass into the past and catching just one
blurred and tantalizing glimpse of this Thing, shambling
through the bleak wilderness, clambering to avoid the sabre-
toothed tiger, watching the woolly rhinoceros in the woods.
Then before we can scrutinize the monster, he vanishes. Yet
the soil is littered abundantly with the indestructible
implements he chipped out for his uses.</p>

<p>Still more fascinatingly enigmatical are the remains of a
creature found at Piltdown in Sussex in a deposit that may
indicate an age between a hundred and a hundred and fifty
thousand years ago, though some authorities would put these
particular remains back in time to before the Heidelberg jaw-
bone. Here there <span class="pagenum"><SPAN name="P47"></SPAN></span>are the remains of a thick sub-human
skull much larger than any existing ape’s, and a
chimpanzee-like jaw-bone which may or may not belong to it,
and, in addition, a bat-shaped piece of elephant bone
evidently carefully manufactured, through which a hole had
apparently been bored. There is also the thigh-bone of a
deer with cuts upon it like a tally. That is all.</p>

<p>What sort of beast was this creature which sat and bored
holes in bones?</p>
<p>Scientific men have named him Eoanthropus, the Dawn Man. He
stands apart from his kindred; a very different being either
from the Heidelberg creature or from any living ape. No
other vestige like him is known. But the gravels and
deposits of from one hundred thousand years onward are
increasingly rich in implements of flint and similar stone.
And these implements are no longer rude
“Eoliths.” The archæologists are presently
able to distinguish scrapers, borers, knives, darts, throwing
stones and hand axes ....</p>
<p>We are drawing very near to man. In our next section we
shall have to describe the strangest of all these precursors
of humanity, the Neanderthalers, the men who were almost, but
not quite, true men.</p>
<p>But it may be well perhaps to state quite clearly here that
no scientific man supposes either of these creatures, the
Heidelberg Man or <i>Eoanthropus</i>, to be direct ancestors
of the men of to-day. These are, at the closest, related
forms.</p>
