The morphologies of creatures and the neural systems for controlling their muscle forces are both generated automatically using genetic algorithms. Different fitness evaluation functions are used to direct simulated evolutions towards specific behaviors such as swimming, walking, jumping, and following.A genetic language is presented that uses nodes and connections as its primitive elements to represent directed graphs, which are used to describe both the morphology and the neural circuitry of these creatures. This genetic language defines a hyperspace containing an indefinite number of possible creatures with behaviors, and when it is searched using optimization techniques, a variety of successful and interesting locomotion strategies emerge, some of which would be difficult to invent or built by design.<br /> <br /> == Extended Abstract ==<br /> <br /> == Bibtex == <br /> <br /> == Used References ==<br /> Nichael Lynn Cramer, A Representation for the Adaptive Generation of Simple Sequential Programs, Proceedings of the 1st International Conference on Genetic Algorithms, p.183-187, July 01, 1985<br /> <br /> Dawkins, R., The Blind Watchmaker, Harlow Longman, 1986.<br /> <br /> Roy Featherstone , Kluwer Academic Publishers, Robot Dynamics Algorithm, Kluwer Academic Publishers, Norwell, MA, 1987<br /> <br /> Hugo de Garis, Genetic programming, Proceedings of the seventh international conference (1990) on Machine learning, p.132-139, June 1990, Austin, Texas, United States<br /> <br /> David E.
