The Proterozoic Record of Eukaryotes (2015, background): “…through a wide variety of geochemical and sedimentological proxies (e.g., Lyons et al. 2014; Li et al. 2013), whereas the record of life is reconstructed solely from the fossil record and molecular clocks (Peterson et al. 2004; Knoll et al. 2006; Erwin et al. 2011; Parfrey et al. 2011).”
Measuring rates of phenotypic evolution and the inseparability of tempo and mode (2012, background): “Why was morphological evolution so fast during the Cambrian Explosion of animal body plans (Marshall 2006; Erwin et al. 2011)? How much faster are punctuations compared to stasis (Gould and Eldredge 1977; Gingerich 1985)? Do some aspects of morphology evolve faster than others, and do some condition”
The Laurentian record of Neoproterozoic glaciation, tectonism, and eukaryotic evolution in Death Valley, California (2013, background): “The apparent coincidence between Neoproterozoic glacial events and the appearance of animals in the fossil record (Erwin et al., 2011; Love et al., 2009; Macdonald et al., 2010b; Peterson et al., 2008; Yin et al., 2007) has fueled speculation concerning the relationships between extreme climate…”
The Anthropocene biosphere (2015, background): “Coincident with the second and third temporal assemblages of Ediacarans are trace fossils (Erwin et al., 2011) that likely indicate the seabed activity of animals with bilateral symmetry.”
Late Ediacaran redox stability and metazoan evolution (2012, neutral): “Independently of Kimberella, and consistent with the predictions of molecular clocks (Erwin et al., 2011), trace fossils in the Redkino succession indicate a modest diversity of bilaterian animals.”
Early evolution of the Eukaryota (2015, background): “For what it is worth, recent molecular estimates for the appearance of the ‘last animal common ancestor’ (LACA) also fall within this same middle Neoproterozoic window (Erwin et al. 2011; Parfrey et al. 2011).”
Origin and early diversification of the phylum Cnidaria Verrill: major developments in the analysis of the taxon's Proterozoic–Cambrian history (2014, background): “The analysis of Erwin et al. (2011), based on seven different housekeeping genes from 118 metazoan taxa, suggests a Cryogenian origin for Cnidaria and an Ediacaran origin at least for Anthozoa.”
Animal Phylogeny and Its Evolutionary Implications (2014, background): “The generally endorsed framework for animal diversification predicts Neoproterozoic divergences and Cambrian radiation (Erwin et al. 2011).”
The Ecological Physiology of Earth's Second Oxygen Revolution (2015, background): “Molecular divergence estimates and the organic geochemical record agree that animals probably originated during the later Tonian or Cryogenian Periods (Figure 4; Love et al. 2009, Erwin et al. 2011), hundreds of millions of years before the inferred Ediacaran-Cambrian oxygenation event.”
Birth and early evolution of metazoans (2014, background): “…phyla, but 4 phyla (Gastrotricha, Gnathostomulida, Micrognothozoa, and Cycliphora) lack fossil record, and additional 3 phyla first appeared in post-Cambrian, Nemertini in the Carboniferous, Platyhelminthes in the Paleocene, and Rotifera in the Eocene (see references in Erwin et al., 2011; Fig.”
