FRAGMENT FROM NATURE is about reverse speciation, which is almost a Darwinian heresy. Niche exploitation by becoming increasingly specialized has been well studied, exemplified in Darwin’s finches and in orchid-pollinator relationships. As species become more specialized, breeding isolation results in the formation of new species. For a long time, biologists thought that there were examples where specialization could lead to evolutionary dead-ends and species extinction. In recent years, this has been re-examined.
