The studies thus far, using evolutionary game theory and genetic algorithms, indicate that truer perceptions are not necessarily fitter, and that a simple interface strategy can drive true perceptions to extinction. ... In short, perception seems to be tuned to fitness rather than truth.

Does evolution make things better?

Evolution does not make a species 'better', but natural selection – the mechanism that drives evolution – selects for traits that improve an organism's chance of survival and reproduction. ... The result is a species that is not necessarily better than its ancestors, but better suited for reproductive success.

Does evolution choose which species to favor?

Populations, not individual organisms, evolve. ... — evolution just doesn't work that way. New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population.
