The Cambrian Conundrum: Early Divergence and Later Ecological Success in the Early History of Animals
TLDR
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. Expand
Phylogenetic-signal dissection of nuclear housekeeping genes supports the paraphyly of sponges and the monophyly of Eumetazoa.
The relationships at the base of the metazoan tree have been difficult to robustly resolve, and there are several different hypotheses regarding the interrelationships among sponges, cnidarians,Expand
The colonization of land by animals: molecular phylogeny and divergence times among arthropods
TLDR
The consistent support for a close relationship between myriapods and chelicerates, using mitochondrial and nuclear genes and different methods of analysis, suggests that arthropods may have adapted to the terrestrial environment relatively late in their evolutionary history. Expand
MicroRNAs and phylogenomics resolve the relationships of Tardigrada and suggest that velvet worms are the sister group of Arthropoda
TLDR
The study confirms the monophyly of the legged ecdysozoans, shows that past support for a Tardigrada + Nematoda group was due to long-branch attraction, and suggests that the velvet worms are the sister group to the arthropods. Expand
Molecular Timetrees Reveal a Cambrian Colonization of Land and a New Scenario for Ecdysozoan Evolution
TLDR
A timescale of ecdysozoan evolution is presented based on multiple molecular data sets, the most complete set of fossil calibrations to date, and a thorough series of validation analyses, which converge on an Ediacaran origin of all major ecdy sozoan lineages. Expand
Poriferan paraphyly and its implications for Precambrian palaeobiology
TLDR
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. Expand
Integrated genomic and fossil evidence illuminates life’s early evolution and eukaryote origins
TLDR
The last universal common ancestor of cellular life is found to have predated the end of late heavy bombardment, and a timescale of life is derived, combining a reappraisal of the fossil material with new molecular clock analyses. Expand
A congruent solution to arthropod phylogeny: phylogenomics, microRNAs and morphology support monophyletic Mandibulata
TLDR
The phylogenomic analyses strongly support Mandibulata, and show that Myriochelata is a tree-reconstruction artefact caused by saturation and long-branch attraction, and provide strong support for the inclusion of pycnogonids in a monophyletic Chelicerata, a paraphyletic Cycloneuralia, and a common origin of Arthropoda. Expand
The Ediacaran emergence of bilaterians: congruence between the genetic and the geological fossil records
TLDR
The two historical records of life both suggest that although the cradle of Metazoa lies in the Cryogenian, and despite the explosion of ecology that occurs in the Cambrian, it is the emergence of bilaterian taxa in the Ediacaran that sets the tempo and mode of macroevolution for the remainder of geological time. Expand
Dinosaurs and the Cretaceous Terrestrial Revolution
TLDR
It is concluded that dinosaurs did not experience a progressive decline at the end of the Cretaceous, nor was their evolution driven directly by the KTR, and major diversification shifts occurred largely in the first one-third of the group's history. Expand
