Abstract. One of the commonest explanations for the evolutionary radiation of animals during the Cambrian and Ordovician periods (about 541 to 443 million years ago) is the predation hypothesis. According to this widely cited but untested idea, the first rise of predatory animals would have accelerated evolution, and so diversification, by increasing natural selection on preys and starting predator-prey coevolutionary arms races. This predation-diversification hypothesis is here tested for the… 

Phanerozoic evolution—Ediacaran biota

Avian predation intensity as a driver of clinal variation in colour morph frequency

Examining the covariation of physiology, environmental variables and colouration at a local scale and a broad-scale analysis to identify whether these factors also explained the latitudinal variation of morph frequency in Liopholis whitii provides key insights into the evolution of local adaptation as well as the ecological forces involved in driving the dynamics of colour polymorphism.

The impact of tectonic-style on marine transgression and evolution

Plate tectonics drives variation in sea-level, over intervals of approximately107–108years. These variations may have significant effects on the pace of (biological) evolution through the elimination

The glow of the night: The tapetum lucidum as a co‐adaptation for the inverted retina

It is hypothesize that the tapetum lucidum is a compensatory adaptation for the suboptimal design of the inverted retina of vertebrates.

Strong coupling of predation intensity and diversity in the Phanerozoic fossil record

A species-level database of predation intensity, as measured by the frequency of common predation traces, suggests that macroevolutionary and macroecological patterns share common causative mechanisms that may reflect either historical processes or sampling artifacts.

Borings in Cloudina Shells: Complex Predator-Prey Dynamics in the Terminal Neoproterozoic

This study corroborates the existence of shell-drilling predation in the uppermost Neoproterozoic of China and shows prey selectivity and site-specific behavior, pointing to a level of Precambrian predator-prey interaction that approaches the complexity seen in younger Paleozoic benthic animal communities.

The effects of competition and predation on diversification in a model adaptive radiation

This work shows experimentally how predation by a protist, Tetrahymena thermophila, affects diversification in a model adaptive radiation of the bacterial prey, Pseudomonas fluorescens, and suggests that predation may play an under-appreciated role in driving adaptive radiations.

Origins and Early Evolution of Predation

Although predation was a decisive selective force in the Cambrian explosion, it was a shaper rather than a trigger of this evolutionary event, representing the transition from simple, mostly microbial, ecosystems to ones with complex food webs and second- and higher-order consumers.

Explaining the Cambrian "Explosion" of Animals

The Cambrian “explosion” is a unique episode in Earth history, when essentially all the animal phyla first appear in the fossil record and is best understood as being the result of the interplay of the combinatorial bilaterian developmental system and the increase in the number of needs the first bilaterians had to meet as complex ecological interactions developed.

The mid-Paleozoic precursor to the Mesozoic marine revolution

The mid-Paleozoic radiation of durophages and response of the marine fauna was in many respects similar to events of the Mesozoic Marine Revolution, in effect, the Paleozoic precursor to that event.

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.
