This page describes a study of one of many speed-oriented evolution runs. Studying evolution is possible because the simulator can periodically save a gene pool state. Thus we keep track of changes in populations during the evolutionary process. Sometimes it is hard to find the first species with some property, because such a species is usually created between saved "snapshots". This is analogous to the problems of biologists examining fossil records and the punctuated equilibrium phenomenon.
Note that this experiment was performed a long time
ago and now the following creatures would behave
differently due to improvements in simulation. However, you can
see their original movement in these movies:
3.3 MB or in high quality:
20 MB. Refer to the publications
to read in detail about current research and results.
One of the first species which had a moving leg controlled by
a touch (T) receptor. You can find parts of the older ways of locomotion
in its genotype. It does not move efficiently, in fact it is merely
creeping.

After some evolution: the construction and neural network have been
cleared from redundant parts. Still not very stable, sometimes
drags its "head" on the ground.

A bit improved: walking. One neuron, one receptor, one muscle.
Touching the ground with the receptor causes bending of a leg.
The leg is straightened when the receptor does not touch anything.
