The lessons we learn from nature...
Zach Barth has coded a simple package that can be used to create evolving algorithms. When introduced to a certain environment, the algorithm pays attention to what works best, randomly alters itself with Zach's code, and when something works out better, it keeps the change. The rapid response of computers makes this a much faster process than traditional evolution, making me fear for the superiority of the human race.

Luckily, these programs generally more interested in increasing WiFi signal strength than in multiplying endlessly until all of the resources of the world are consumed.
