Even if some of the listed examples are not directly transitional or ancestral to modern species, they are still intermediate forms, occurring in expected geologic horizons that are entirely compatible with evolution, but contradict expectations of YECism and hopeful monster ideas. Davison apparently fails to consider that one reason we don’t have even more intermediates is that by all evidence speciation often takes place in small and/or isolated populations (and again, over relatively short geologic time spans), explaining why they are less likely on average to leave fossils than large, stable populations persisting for longer spans. But again, despite all this, many of intermediate forms have been documented, with new ones turning up on a fairly regular basis (witness Tiktaalik, all the feathered dinos from China, etc).
