No, I don't think so. All models are incomplete simulations of a target environment. Were they fully complete, one would simply build a large series of full scale prototypes. What the model offers is an opportunity to build out a series of 'toy' prototypes very cheaply, and then use aspects of the results in the final product based on a series of assumptions built into the simulation. However, there is always accepted drift from simulated to final real-world results. Monte Carlos are a prime example of this. http://en.wikipedia.org/wiki/Monte_Carlo_method >What this means, then, is that using the earth as a laboratory >for an evolutionary experiment would make sense only if the >result were to be applied on earth.

From this perspective, as I noted, the simulated model is the real world design - which would make it a prototype and not a model. Best, Maynard Listen to 'Strange Days...
