own line to begin the bridgework. Then she flashes a message to Bianca and the two of them begin to descend.
    The hairy hunter below is intent on its own hunger – the forest is not short of prey species of varying sizes, many of them abortive results of the nanovirus’s work. There are some surviving vertebrate species – mice, birds, dwarf deer, snakes – but the virus has tried and failed with them. Kern’s experiment called for monkeys, and she ensured that the green planet’s chosen would suffer no competition from close cousins. The vertebrates that the monkeys were intended to interact with were designed to reject the virus. They have changed hardly at all.
    Nobody considered the invertebrates, the complex ecosystem of tiny creeping things intended to be nothing more than a scaffolding by which the absent monkeys would ascend.
    In so many cases – as with the great tarantula-descendant below that Portia is considering – whilst the virus was able to provoke growth, the sought-for neural complexity never arose. Often the environmental pressure to select for such a facility was simply lacking. A sense of self and the ability to contemplate the universe are not necessarily survival traits in and of themselves. Portia is a rare exception – though not the only exception – where increased cognitive capacity granted an immediate and compelling advantage.
    The carpet-like hunter stops, the faintest of vibrations reaching it. The forest floor is strewn with its thread, forming a messy but effective sense organ that alerts it to the movements of its prey. Against a creature as simple as this, Portia and her kin prefer hunting methods that have not changed in thousands of years.
    Portia has discerned the pattern of threads below, running through the leaf litter, almost hidden save to eyes as keen as hers. She reaches down with a foreleg and plays them carefully, speaking eloquently the language of touch and motion, creating a phantom prey, and giving it the illusion of size, distance and weight entirely conjured by her skill. She places herself in the primitive mind of the ground-hunter, as surely as if she could actually implant her thoughts there.
    It advances a handful of steps, testing out this sensation, not wholly convinced. She wonders if it has had some near-escapes with her kind before. The great shaggy abdomen is up, ready to shake out a cloud of barbed hairs that will choke Portia’s book-lungs and irritate her joints.
    She reaches down gingerly again, prying and tugging, suggesting that the illusory prey is getting further away, soon to escape entirely. Her body is mottled and irregular as her ancestors’ were, and the ground-hunter’s simple eyes have not made her out.
    It takes the bait suddenly, in a hairy rush across the forest floor towards nothing, and Bianca drops on its back, fangs first, driving them in where its legs meet its body, and then springing away a few body-lengths to be out of the way of any riposte. The hunter lunges after her, but stumbles even as it does so, abruptly unsteady. Moments later it is twitching and quivering as the venom takes effect, and the two females wait for it to grow motionless – though still alive – before closing in to feed. Bianca in particular remains taut for another leap to escape if need be, her abdomen heaving slightly in and out as she forces air past her book-lungs.
    Up above, the male is looking down plaintively and, when Portia checks on him, he signals for permission to feed. She tells him to finish his work first.
    A moment later he has dropped down practically on top of her, sending her leaping instinctively backwards, landing clumsily and flipping onto her back before righting herself angrily. Bianca has come within a whisker of killing the male, but he is stamping and signalling frantically:
Danger coming! Danger! Spitters!
    And he is right: here come her kind’s ancestral foes.
    The spitting spiders, the Scytodes, have marched in step with
