Since the publication of Darwin (1859), the biological meaning of the Cambrian radiation has been debated. Most commentators agree, however, that the Cambrian radiation is fundamentally a time of major metazoan cladogenesis. In and of itself this does not necessarily mean that unique evolutionary processes operated during the Cambrian radiation. Phylogenetic analysis has been used to study the tempo of speciation during the radiation, and thus far there is no need to invoke special rules… 

Taking the Pulse of the Cambrian Radiation1

Early Cambrian olenellid trilobites revealed the signature of the breakup of Pannotia, a tectonic event that most evidence suggests is constrained to the interval 600 to 550 Ma, which suggests the phylogenetic proliferation associated with the Cambrian radiation was underway tens of millions of years before the Early Cambrian, although not hundreds of Millions of years as some have argued.

MACROEVOLUTIONARY PATTERNS AND PROCESSES DURING THE CAMBRIAN RADIATION: INTEGRATING EVIDENCE FROM FOSSILS AND MOLECULES

Several lines of evidence are discussed that provide additional understanding about the Cambrian radiation including trilobite phylogeny and biogeography, cnidarian fossils and phylogenies, metazoan phylogenies and the molecular clock, genomics and evolutionary development, and palaeoecology.

A critical reappraisal of the fossil record of the bilaterian phyla.

It is shown that the prospect of lineage diversification occurring early in the Proterozoic can be seen to be unlikely on grounds of both parsimony and functional morphology, and this analysis points to the requirement for a careful application of systematic methodology before explanations are sought for alleged patterns of constraint and flexibility.

The good fit of this model to data on Phanerozoic familial diversity suggests that many of the large-scale patterns of diversification seen in the marine fossil record of animal families are simple consequences of nonlinear interrelationships among a small number of parameters that are intrinsic to the evolutionary faunas and are largely (but not completely) invariant through time.
