Taking evolution to mean the Darwinian mechanism of mutation and natural selection, nearly everyone agrees that this occurs on the microevolutionary level. The question is, does this mechanism give evidence that it is adequate to explain the much larger diversity that we see at the upper levels of the biological classification scheme? Currently it does not, suggesting that something rather different is at work on these levels. In this sense, it appears that evolution is a historical theory without an adequate known mechanism, more like Everett's many-worlds theory of quantum mechanics or Setterfield's theory of a changing speed of light than like continental drift or climate change due to long-term variation in the earth's orbit.
