And another mainstay of creationism - the nonsensical dogma that new species can't arise by evolution - comes crashing down, as does the dogma that speciation has never been observed.
Evolution is primarily driven by environmental change because these changes open up new opportunities for random variations to be an advantage in, so creating something for natural selection to select for (or not to select against). In this way, biodiversity feeds upon itself to give more biodiversity.
