Also, I would write <i>by humans</i>, not <i>by ants</i>.<p>One could also have a deep philosophical discussion whether ants actually can discover anything (how much consciousness&#x2F;ability to abstract&#x2F;... is needed for that, and do ants posses it? Or maybe, do ants lack it, but ant colonies have it? Or is it DNA that discovered it using a genetic search algorithm?)
