Besides, as nature shows, there are many evolution steps between "ground" and walking creatures. Arby: In my demo the joints are 100% stiff, therefore the creatures bend down by their own choice.

I think the reason the walking one always ends up as a ground creature is that maybe you're not evolving the "spine" of the torso? To me after running it only twice, looks like the torso segment rotates down quite easily and quickly. This would imply to me that gravity pulls at it, and it being hinged rather than "spine-like" sets up your creature to never be able to walk upright. We do not walk upright by balancing our upper body as if it were on a pivot. There's lots of muscle all around to keep our "pivot" rather difficult to flex, really. So do a version where the pivot stiffness changes too. Very interesting.
