It's not a model of the worm's genome, let alone its full development required to actually produce the worms, let alone of populations of the worms, let alone populations of the worms interacting with a full blown natural environment. Which is what determines what happens in natural selection.

Evolution does not naturally tend toward complexity, it tends toward fit to the environment. In one case that may be specializing in eating eucalyptus leaves. In another case it might be having a big brain. We tend to think that the whole direction of evolution is toward producing us but there is no basis for that in evolutionary theory. We ended up with particular traits because they were available in our population and gave our ancestors a leg up in their specific environments.
