    Nicholas J Butterfield
    Department of Earth Sciences, University of Cambridge, Cambridge, CB2 3EQ
    Bioessays 28:1161-6. 2006
    ..Despite their close relationship, these two jawed, segmented worms could conceivably represent the early stages of two separate phyla...

    Department of Earth Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EQ, United Kingdom
    Proc Natl Acad Sci U S A 102:1554-9. 2005
    ..These results support molecular analyses that identify the calcarean-silicisponge transition as the earliest major sponge branch and suggest that the heteractinids were paraphyletic with respect to the Hexactinellida...

    Thomas H P Harvey
    Department of Earth Sciences, University of Cambridge, Downing Street, Cambridge, CB2 3EQ, UK
    Nature 452:868-71. 2008
    ..This Early Cambrian record predates the major expansions of large-bodied, particle-handling crustaceans by at least one hundred million years, emphasizing the importance of ecological context in driving adaptive radiations...

    Kevin J Peterson

    Proc Natl Acad Sci U S A 102:9547-52. 2005
    ..Thus, the more readily preserved microfossil record provides positive evidence for the absence of pre-Ediacaran eumetazoans and strongly supports the veracity, and therefore more general application, of the ME molecular clock...
