In the case of cars and other engineered objects, humans go about the design process in a very intentional way. They pretty much know what they are aiming for. The activity described in this article demonstrates how a computer can simulate biological evolution and the laws of natural selection. The article is divided into the following sections: (1) A Different Kind of "Designer"; (2) Lessons from Nature; (3) Evolution in Fast-forward; (4) An "Out-of-the-Box" Antenna Design; and (5) May the Best Face Evolve [classroom activity].
