The basic Tierra model has been used to experimentally explore '') although this promise has not been realized – like most other open-ended digital evolution systems, it eventually comes to a point where novelty ceases to be created, and the system at large begins either looping or evolving statically; some descendant systems like Avida try to avoid this pitfall. While the dynamics of Tierra are highly suggestive, the significance of the dynamics for real ecological and evolutionary behavior are still a subject of debate within the scientific community. Tierra is an abstract model, but any quantitative model is still subject to the same validation and verification techniques applied to more traditional Mathematical Model s, and as such, has no special status. More detailed models in which more realistic dynamics of biological systems and organisms are incorporated is now an active research field (see Systems Biology ). SEE ALSO
