Coolest... Simulation... Ever
(via Pharyngula) Ey wrote a simulation to evolve watches (clocks actually, but same diff) to counter the whole "watch found on a beach" argument against the theory of evolution. I must salute em, not only for extreme dorkitude in the face of adversity ("honey, it's 2 in the morning, come to bed"), but for writing and then explaining one of the coolest population simulations I've ever ever seen.
I'm especially impressed by how the simulations accurately capture the historical contingency implied by the theory of evolution. Every time ey runs the sim ey gets different results over different periods of time, nicely countering any number of "just so" stories.
