  • The organisms within each kingdom can then be further divided into different groups called phyla (fie 'luh), the singular of which is phylum (fie' lum).

  • Neo-Darwinism and front-loaded hypotheses expect the opposite pattern, a ‘bottom-up’ pattern in which small differences in form accumulate first differentiating species and genera from each other and then only much later building to the large-scale differences in form that differentiate higher taxonomic categories such as phyla and classes.

  • Meyer asserts that the Cambrian explosion represented an actual sudden origin of higher taxa; that these taxa such as phyla are “real” and not an artifact of human retrospective classification; and that morphological disparity coincides with phyletic categories.

  • It is Meyer's opinion (as mentioned in other articles) that the "Cambrian Explosion" is the time when "40 separate major groups of organisms or" phyla "(including all the basic body plans of modern animals) emerged suddenly without clear precursors.".
