The free will of fruit flies

Simplifying a poorly written research paper: Scientists at the Free University of Berlin may have found the basis of free will by studying the flight of fruit flies.

How?

Researchers tethered flies in a white container, giving the fly no visual cues. Then they recorded the flies movement.

The researchers thought that they could then model the fly's movememt in a computer - but they couldn't.

Why? The researchers were testing the hypothesis that insects are simple bio-mechanical automatons (lttle protein robots.) If that was true, then there movement should have been random, like background noise.

What they found was that the non-random movement of the fly suggested choice - free will.

The scientists think that "free will" is somewhere between chance and neccessity - so instead of the question "Do I have free will", we should be asking "How close to free will am I?"
