This is Micheal Levin-level mind blowing. His theory can be shortened to "there's intelligence in really small discrete parts of Biological entities".

> The team combined multiple lines of evidence. They used a high-speed camera to film real butterflies taking off at over 1,000 frames per second to capture how their patterns behave in flight, as seen through the eyes of a bird.

> To test how patterns affected real attacks, 100 volunteers acted as “predators”, trying to catch virtual butterflies on a touchscreen.

This sounds fascinating, and I'd love to see footage demonstrating the barber-pole effect. If that's not available, I'd alternatively love to see footage of volunteers trying to tap butterflies on an iPad.
