"Larger-scale changes evident over longer periods of life's history".... are based on interpreting the fossil record using evolution as your apriori assumption, hence they are only evident in the minds of evolutionists. The real observation is that different kinds of creatures are buried in the fossil record. In spite of the dogmatic enthusiastic assertions by Dawkins, Attenborough, etc. evolution is a belief held by faith, not an observable fact. (Ref. philosophy, world view, scientific method.)Prof Ed Neeland.
