Nothing explicitly forbids that from occurring, but in this program it seems to be an extremely rare occurrence. As long as the environment and fitness function stay the same, these creatures tend to converge on a particular body plan early on and then just adjust it slowly over time (again, that's not explicitly programmed, it just tends to unfold that way). If the environment were to change more often, I would think that should provoke greater change, but I haven't done many runs like that.
It could, but it hasn't happened. I let this worm evolve an extra 2000 generations (small population size of 20 or so) just to see what would happen. It gained some speed (about 40% faster than the original end-over-end worm), but the body didn't change except for subtle changes in proportions. Mutants appear all the time with extra appendages and things like that but so far none of those ever performed well enough to compete with the 'regular' worms.
Just curious, do your creatures have a particular direction or destination to travel to be "fit", or is it simply their final distance from their origin?
Also, I've been trying to check out your website but the link in youtube doesn't work... Did you move it somewhere?
It's the latter. They have no particular direction. It's the greatest distance they reach from their origin during their allotted time.
Sorry about the website. It went down a few days ago for some unknown reason. My web host is looking into it and expects it to be back in a day or so. I have a copy posted elsewhere in the meantime. If you message me in youtube I can send you the URL (IIRC, youtube comments forbid URLs).
Wow...that little worm guy just keeps going no matter what!
I'm not having as much luck yet with my oscillation-free critters, but it's only generation 60 or so. I also started up another oscillation-free evolution on my Linux box with slightly different settings; we'll see what happens.
I'm not sure of the extent to which it matters, but in terms of settings: #60 in the zoo was evolved with a population size of only 20, and 1000 time units for eval. It was later switched (with a bit of file-tinkering) to a population size of 10, 7 eval-repeats (to get a good avg), and 3000 time units for eval, plus lowered mutation rates.
Perhaps those are good settings. Hard to say at this point.
can the creatures evolve more appendages?

so the worm can't have an extra box?
Are you Mr. H on my freewebs sight? If so we could communicate faster there. I'm on it now

Oops! Forgot the second part. No, I'm not Mr. H on freewebs.

Thats impressive! Like the worm movement, looks really good ;_)

It's definitely my favorite evolved critter so far. Probably worth evolving further, just to see what it might come up with :)

(in case I wasn't clear - it's that second configuration that lead from creature #60 to the current "super-worm")
