Unravelling the timing of the metazoan radiation is crucial for elucidating the macroevolutionary processes associated with the Cambrian explosion. Because estimates of metazoan divergence times derived from molecular clocks range from quite shallow (Ediacaran) to very deep (Mesoproterozoic), it has been difficult to ascertain whether there is concordance or quite dramatic discordance between the genetic and geological fossil records. Here, we show using a range of molecular clock methods that…

Fossil steroids record the appearance of Demospongiae during the Cryogenian period

It is suggested that shallow shelf waters in some late Cryogenian ocean basins contained dissolved oxygen in concentrations sufficient to support basal metazoan life at least 100 Myr before the rapid diversification of bilaterians during the Cambrian explosion.

Phylogenomic insights into the cambrian explosion, the colonization of land and the evolution of flight in arthropoda.

The results provide insights into the 3 independent colonizations of land by arthropods and suggest that evolution of insect wings happened much earlier than the fossil record indicates, with flight evolving during a period of increasing oxygen levels and impressively large forests.

Molecular paleobiology of early-branching animals: integrating DNA and fossils elucidates the evolutionary history of hexactinellid sponges

This study illustrates the potential of an integrated molecular/paleobiological approach to reconstructing the evolution of challenging groups of organisms by inferring divergence times of crown-group Hexactinellida in a Bayesian relaxed molecular clock framework.

The Cambrian Conundrum: Early Divergence and Later Ecological Success in the Early History of Animals

A compilation of the patterns of fossil and molecular diversification, comparative developmental data, and information on ecological feeding strategies indicate that the major animal clades diverged many tens of millions of years before their first appearance in the fossil record.

Morphological novelties detonated the Ediacaran—Cambrian “explosion”

The ‘‘Cambrian explosion’’ is now thought by many evo-lutionary biologists to comprise two phases: (i) cladogenesis inthe Precambrian (Parker 2003; Peterson et al. 2008); and then (ii) hard-part evolution (leading to more dynamic lifestyles and ecology) in the Early Cambrian.

Ediacaran distributions in space and time: testing assemblage concepts of earliest macroscopic body fossils

Abstract. The mid-late Ediacaran Period (∼579–541 Ma) is characterized by globally distributed marine soft-bodied organisms of unclear phylogenetic affinities colloquially called the “Ediacara

Remarkable insights into the paleoecology of the Avalonian Ediacaran macrobiota




Origin of the Eumetazoa: testing ecological predictions of molecular clocks against the Proterozoic fossil record.

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.

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.

Poriferan paraphyly and its implications for Precambrian palaeobiology

It is demonstrated, in accordance with previous molecular studies, that sponges are paraphyletic, and that calcisponge are more closely related to eumetazoans than they are to demosponges.

It is proposed that despite its step-like function this evolutionary event is the inevitable consequence of Earth and biospheric change.

Tempo and mode of early animal evolution: inferences from rocks, Hox, and molecular clocks

Abstract One of the enduring puzzles to Stephen Jay Gould about life on Earth was the cause or causes of the fantastic diversity of animals that exploded in the fossil record starting around 530

A molecular timescale for vertebrate evolution

The clock-like accumulation of sequence differences in some genes provides an alternative method by which the mean divergence time can be estimated, and the molecular times agree with most early and late fossil-based times, but indicate major gaps in the Mesozoic fossil record.


The fossil record documents two mutually exclusive macroevolutionary modes separated by the transitional Ediacaran Period, which reinvented the rules of macroecology through their invention of multitrophic food webs, large body size, life-history trade-offs, ecological succession, biogeography, major increases in standing biomass, eukaryote-dominated phytoplankton and the potential for mass extinction.

An alternative view is discussed, in which acoelomorph flatworms, which do not belong to the Platyhelminthes, represent the earliest extant bilaterian clade, and this reconstruction backs the old planuloid–acoeloid hypothesis and may help the understanding of the evolution of body axes, Hox genes and the Cambrian explosion.
