It was an intimidating sight; the valley was exposed, utterly open. And yet he must cross it.
And from here, now that there was no forest to soak up the noise, he could make out that great, mysterious roaring from the west. The remote noise sounded like the groaning cry of some huge, pained, angry beast, or like the thunderous hoofs of some great herbivorous herd. But when he looked to the west he could see no dust clouds, no black wash of animal bodies. There was nothing but the roaring, continuing just as it had all his life.
He began to clamber down the rocky slope, still heading south.
The ground became bare. Still trees clung to life here, their roots wormed into faults in the rock. But these pines were sparse, their leaves spiky, jealous of their water. He stopped under one of these trees. Its branches and leaves offered him virtually no shade. He could find no fruit, and the leaves he plucked were sharp and dry in his mouth. He made a grab for a small mouselike creature with long, levered hind legs; his mouth watered at the thought of biting into its soft wet body, its small bones crunching in his mouth. But here on this rocky ground he was clumsy and noisy, and the mouse thing evaded him easily.
Now the ground changed again, becoming a broad slope of broken stone that spread out before him, a road leading to the depths of the dry valley. The going got even harder as Capo slid and slipped on the loose rubble. Hot, thirsty, hungry, scared, he hooted his protest and threw bits of the rubble around, tramping and kicking it. But the land was not to be intimidated even by Capo’s mighty displays.
Meanwhile the chasma watched the ragged group of anthropoids as they struggled down the uneven, treacherous slope.
She had never seen creatures like this before. With a predator’s cold interest, she made unconscious calculations of their speed, strength, and meat yield, and began categorizing the individuals — here was one who seemed wounded and limped a little; here was an infant, clasped tightly to its mother’s chest; here was a juvenile straying, foolishly, from the tight group.
This chasmaporthetes was actually a kind of hyena. But, long legged, slim, she looked more like a cheetah. She did not have all of the true cats’ suppleness and speed, not quite; her kind had more adapting to do in the fleet conditions of this emerging world of grass. But her range was huge in this barren valley. She was the top predator here, and she was well equipped for her grisly work.
To her, the apes were new meat on the savannah. She waited, her eyes glowing like captive stars.
At last, exhausted, Capo gave up. He slumped to the ground. One by one, what was left of his troop joined him. By the time they had all arrived, the sun had started to set, filling the sky with fire and casting long, stark shadows along the floor of this gravel-littered bowl.
A kind of dull indecision raged within Capo. They shouldn’t stay here, out in the open; his body longed to climb a tree trunk, to pull together branches to make a cozy, warm, safe nest. But there were no trees here, no security to be had. On the other hand they couldn’t cross the valley floor in the dark. And they were all hungry, thirsty, exhausted.
He didn’t know what to do. So he did nothing.
The troop began to disperse, following their own instincts. Finger picked up a cobble-shaped, palm-sized rock, perhaps hoping to use it in some future nut-cracking project. But a scorpion scuttled out from beneath the rock, and Finger fled, hooting.
Frond was sitting alone with his back to the rest of the group, assiduously working at something. Capo, suspicious, loped up as quietly as he could on this loose, scattered gravel.
Frond had found a termite mound. He was sitting before it, clumsily poking sticks into it. When he saw Capo he cowered, screeching. Capo delivered brisk, perfunctory blows to his head and shoulders, as Frond would have expected. He should have hooted to the rest on discovering this bounty.
Capo ripped open a shrub. All of its branches were spindly and bent, and when he stripped a branch by passing it through his mouth, the hard, spiky leaves hurt his lips. But it would have to do. He sat alongside Frond. He pushed his stick into a crevice in the mound, and worked it until it had slid in deep. It was not ideal; the stick was too short and bent to be truly effective, but it would have to do. He jiggled it around, waiting patiently. Then he withdrew the stick, centimeter by centimeter. To the stick clung soldier termites, sent to defend the colony from this invader. Capo took great care not to dislodge this cargo. Then he swept the stick through his mouth, enjoying a mouthful of sweet, moist flesh.
When they saw what was going on the rest of the troop crowded around, the older ones making their own fishing sticks. Very quickly a rough pecking order established itself, lubricated by kicks, punches, hoots, and sly grooming. The more senior male and females alike got closest to the mound while the young, who didn’t understand what was happening anyhow, were excluded. Capo didn’t care. He just concentrated on holding his own position close to the mound while working assiduously at the termites.
The termites were antique creatures whose complex society was the result of their own long evolutionary story. This mound was ancient, built of the mud that had pooled here when infrequent rainstorms caused temporary floods. Its rock-hard carapace protected the termites from the attentions of most animals, but not these apes.
Capo’s use of tools — the termite-fishing sticks, the hammer-stones, the leaves he would chew to a sponge to extract water from hollows, even the fine toothpicklike sticks he sometimes used to perform crude dentistry — seemed sophisticated. He knew what he wanted to achieve; he knew what kind of tool he needed to achieve it. He would memorize the location of his favorite tools, like his hammer-stones, and made subtle decisions about using them — for instance trading off the distance he had to carry a hammer against its weight. And it wasn’t a case of just picking up a handy rock, found by chance; he modified some of his tools, like this termite-fishing stick.
And yet he was not like a human craftsman. His modifications were slight: his tools, abandoned after use, would have been hard to distinguish from the products of the inanimate world. The actions he used to make the tools were part of his normal repertoire, like biting, leaf stripping, stone throwing. Nobody had invented wholly new actions, like a potter’s clay throwing or a wood carver’s whittling. He used each tool for one use, and one use only; it never occurred to him that a termite fishing-stick might also be used as a toothpick. He did not improve his tools, once he had found a design that worked. And if — by some chance — he had in the course of his life happened upon a new kind of tool, however successful a design it was, its use would have spread only very slowly through his community, perhaps taking generations to reach every member. Coaching, the notion that the contents of someone else’s mind might be shaped by rehearsal and demonstration, had yet to be discovered.
So Capo’s tool kit was staggeringly limited, and very conservative. Capo’s ancestors, five million years gone, creatures of a different species, had used tools of only fractionally less sophistication. Capo wasn’t even aware he was using tools.
And yet here was Capo, working assiduously, knowing what he wanted, selecting materials to achieve his goal, making and shaping the world around him, the cleverest so far of all of Purga’s long line of descendants. It was as if a slow fire were smoldering in his eyes, his mind, his hands, a fire that would soon burn much more brightly.
As the sun slid beyond the horizon at the valley’s end the apes huddled closer. Deeply unhappy, they pushed, jostled, and slapped, hooting and screeching at each other. This wasn’t their place. They had no weapons to defend themselves, no fire to keep the animals at bay. They didn’t even have the instinct to keep silent at sunset, the hour of predators. All they had was the protection of each other, of their numbers — the hope that another would be taken, not me.
