These simulations are very sensitive to the parameters, some of which we don't even have control over (e.g. population size or what method to select the next generation.) And especially the way the genome is represented.
It doesn't really say how it works, but it doesn't seem like a very natural way to do walking. E.g. here is are evolved walkers in a more complicated 3d simulation: http://vimeo.com/79098420 They seem to get very good after just a few generations compared to this.
Incredible. It even evolves a walker resembling a variant of a kangaroo (at [01:57]). With a target speed of 1.0 m/s, the legs alternate in taking small steps, but at 2.0 m/s, both legs are used to jump.
