The watchmaker is blind: how evolution produces clocks from only randomized parts

Explaining evolution to a believer tends to be hard, because so many of the things that need to happen in order for an organism to evolve require deep understanding of biology. Or, maybe not:

It's an amazing video! The video not only explains evolution, it does so by using a relatively simple computer simulation that is in style these days to produce "intelligent" computer programs. Yes, that's right, evolutive computing through sheer brute force has bested old forms of algorithm development.
