I suppose this might appear to be in questionable taste, given how close we are to Christmas, but I came across a fascinating YouTube video (via Metafilter) which shows the results of a program designed to reproduce the elements of evolution — using rudimentary clocks and clock-related mechanisms as the building blocks of life.

The person who wrote the program intended it as a refutation of the argument that evolution must be wrong because complicated mechanisms such as clocks (and eyeballs) don’t just emerge by themselves. I don’t know whether it solves that debate or not, I just thought it was a cool video — given a supply of hands, gears, springs and other elements that are endowed with affinities similar to biological entities, and an evolution-like system, it seems that clocks eventually emerge.
