Jeff's eyes landed on a nearby insect. The bee had flown through his window, seeking out the flowers in the planter box outside, and was now checking out his dirty washing as if the colorful shirts might be hiding a secret stash of pollen. Jeff closed the window, trapping the clueless insect inside with him and the Chronivac. "Alright, bee, let's see what a few hundred years of evolution does to you."
Setting the parameters to evolve a hundred years a second, he pressed start.
At first, he couldn't see anything happening. Then, after a few seconds, a small bulge was forming in the pile of clothes. He could hear the sounds of buzzing and wings futilely beating as the insect evolved and grew. The new and improved bee crawled out from under the shirts, and Jeff pressed stop.
It wasn't much of an impressive evolution, to Jeff. The bee had gone from half the size of his pinky to the size of a small mouse, but that was it. It didn't seem all that different on the outside. What Jeff didn't know was that it had undergone vast development on the inside. Its brain has developed enormously, now giving it the ability to learn and comprehend the world around it. Its primitive body had made way for a stronger circulatory system and internal skeleton, allowing it to support itself and grow to much larger sizes. Its sting was no longer a suicidal endeavor, and its muscles had become as strong as an ant's, at five times the size. It buzzed as it shook off the confusion of the transformation.
Jeff held out his hand, and the bee vaguely registered it as an invitation and nestled comfortably into the palm of his hand. Jeff looked it over. "Perhaps I didn't do it for long enough." And he pressed transform again.
Now, with the right structures in place to support it, the evolution began to progress much faster. Jeff watched in wonder as its exoskeleton hardened into thick, armored plates that clacked as it shifted. Its stinger grew large as the blade of a knife, and wickedly sharp, able to puncture any skin with ease. Its venom, too, grew deadly enough to drop an elephant with a single dose.
The bee grew larger, quickly going from mouse to cat-sized, then to the size of a puppy. Two deceptively flimsy wings, each as long as Jeff's forearm, beat against its back, lifting the enormous insect out of his now undersized hands so it could land on the bed. It rested there as a fourth pair of legs attached itself to its thorax and a second set of antennae to its head. Jeff ended the transformation.
"Looks like it did a lot more that time," he chuckled, watching the new and improved bee crawled around on his bedsheets. It cocked its head at the sound of his voice and buzzed. "Wait, do you understand me?"
The bee didn't react but kept looking at him with curiosity. Looks like its brain had certainly developed a lot, but it didn't seem to have any new knowledge. Jeff shrugged and turned back to the computer. He fiddled with the settings. "Let's see what else this thing can do."
