Either this has to be a level, or you
really don't understand the Cambrian Explosion.
"Macro" evolution (which is a stupid term, because there really is no distinction as far as natural selection is concerned), the introduction of completely new species diverging from a common ancestor, has in fact been observed in laboratory testing (on fruit flies and plant specimens with no genetic engineering), and in natural settings (on various islands, birds and reptiles have adapted completely new physical structures that were selected for naturally within just a few decades). Cichlid fish have developed completely new strains and as many as half a dozen new and distinct species in the last 4,000 years in a lake where they were known not to have existed before they were introduced. Bacterial and viral "macro" evolution is even more common and more frequently observed.
Of course, this only matters if you shut your eyes to the evidence offered by paleontology (the copious fossil record), biogeography, comparative anatomy (specifically the phenomenon of homologous and vestigial structures), embryology, and especially genetics.
