A brief description of the science of palynology is given. The science is possible because the ornamentation and sculpture of the outer pollen wall or exine is remarkably durable. Palynologists have been able to assign microspore of Cenozoic and Mesozoic rocks to modern families, genera and even species. In the last fifteen years spores of vascular plants have been reported from the Cambrian. Axelrod reports over 60 Cambrian spore genera are now on record. Leclerq believes the finding of spores of woody plants already in the Cambrian raises the question of the polyphyletic origin of vascular plants. This is another way of saying that, as far back as we can trace geologically, plants are as distinct from one another as now. This certainly is strong evidence for an original creation of them as distinctive kinds.
