<p>It seems to add a ripple effect the more I increase the degree, but would like to read about it somewhere more. Couldn't find anything about it with a google/youtube search that specifically explains it. What is it supposed to control precisely?</p>

What does the 'evolution' property under Turbulent Displace in After Effects do?

It's just a quick way of adding movement to the distortion, by evolving the fractals. If you try adjusting the Evolution of a **Fractal Noise** effect you can witness this in action.

Evolution properties are handy as they allow you to **seamlessly loop motion**, by toggling 'Cycle Evolution'. This would require more steps to achieve, if you were animating the **Offset** value, for instance.
