His iconic diagram of the numbers of marine families from the Cambrian to the Recent illustrates the successive expansion and dwindling of three "[[evolutionary fauna]]s" that were characterized by differences in origination rates and carrying capacities. Long-term ecological changes and major geological events are postulated to have played crucial roles in shaping these evolutionary faunas.<ref name="Rojas2021a">{{cite journal |last1=Rojas |first1=A. |last2=Calatayud |first2=J. |last3=Kowalewski |first3=M. |last4=Neuman |first4=M. |last5=Rosvall |first5=M. |title=A multiscale view of the Phanerozoic fossil record reveals the three major biotic transitions. |journal=Communications Biology |date=March 8, 2021 |volume=4 |issue=1 |page=309 |doi=10.1038/s42003-021-01805-y |pmid=33686149 |issn=2399-3642|pmc=7977041 }}</ref>
