I would be wary of using an aesthetic principle in relation to theories of science, but please note the ugliness of the theory of natural selection (although some like Dawkins find it elegant and its ‘elegant’ simplicity, entirely false and misleading). In any case it is a gross oversimplification, almost an hallucination.
By comparison look at the elegance of the eonic model with its compelling exhibition of historical directionality/teleology, free agency versus system action, historical creativity, stream and sequence duality, the evolution of freedom and self-consciousness, and much else.
