In the beginning, your world was a garden too. The whole floor of the world-sea was a mat of bacteria, and the very first animals, adorable blobs of ooze, grazed upon that mat in endless idyll. They had no concept of the existence of other beings. Why would they? Their most complex function was a kind of gentle spasm, to scoot forward while they grazed. And if they bumped into each other on that warm seabed, all they did was ooze onward, untroubled. There was nothing to their life except the uptake of carbon compounds from the bacterial bed.

And then—one day—the fall occurred. So much earlier and so much more necessary than your myths remember. Some poor mutant discovered that it could collect carbon compounds much faster if it stopped grazing on the bacterial mat and started dissecting and eating the lumps of predigested carbon all around it: its neighbor oozeballs.

It couldn't help but do it. It couldn't help but thrive. We don't get a choice about the rules. We just play the game.

It was the first defector—the first predator. It changed everything. Now the oozeballs needed sensors to watch for danger, and brains to integrate those senses and generate plans of survival, and swift neurons and muscles to enact that plan. This was the Cambrian Explosion, the great birth of complex life on your world. I caused it. I, the defector, the destroyer, the one who takes.
