Macroevolution and macroecology through deep time
No full textThe fossil record documents two mutually exclusive macroevolutionary modes separated by the transitional Ediacaran Period. Despite the early appearance of crown eukaryotes and an at least partially oxygenated atmosphere, the pre-Ediacaran biosphere was populated almost exclusively by microscopic organisms exhibiting low diversity, no biogeographical partitioning and profound morphological/evolutionary stasis. By contrast, the post-Ediacaran biosphere is characterized by large diverse organisms, bioprovinciality and conspicuously dynamic macroevolution. The difference can be understood in terms of the unique escalatory coevolution accompanying the early Ediacaran introduction of eumetazoans, followed by their early Cambrian (Tommotian) expansion into the pelagic realm. Eumetazoans 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. Both the pre-Ediacaran and the post-Ediacaran biospheres were inherently stable, but the former derived from the simplicity of superabundant microbes exposed to essentially static, physical environments, whereas the latter is based on eumetazoan-induced diversity and dynamic, biological environments. The c. 100-myr Ediacaran transition (extending to the base of the Tommotian) can be defined on evolutionary criteria, and might usefully be incorporated into the Phanerozoic

Oxygen, animals and aquatic bioturbation: an updated account
No full textThe modern biosphere owes its idiosyncratic expression to the activities of oxygen metabolizing organisms, especially animals and eukaryotes (Butterfield, 2011). And with a permanently oxygenated atmosphere established during the ~2.4 Ga Great Oxidation Event (GOE), the stage was set for their early evolutionary debut. Curiously, however, eukaryotic organisms do not appear in the fossil record for another ~800 million years, and animals for another billion years beyond that (Butterfield, 2015a). Since oxygen availability determines the activity of aerobic organisms, there is a longstanding view that, although free oxygen was certainly present through these extended intervals, it remained persistently below levels necessary to support multicellular animals (Nursall, 1959) – or if not animals per se, at least organ-grade bilaterians (Planavsky et al., 2014) – or if not bilaterians per se, at least the large carnivorous bilaterians capable of driving a major evolutionary radiation like the Cambrian explosion (Sperling et al., 2013). Such ‘permissive environment’ causality provides an intuitively satisfying explanation for the delayed arrival of Phanerozoic-style ecosystems, and is supported empirically by geochemical evidence for the expanding oxygenation of mid-late Neoproterozoic oceans (Och & Shields-Zhou, 2012; Cole et al. 2016; Hardisty et al. 2017)
