The Fractional MacroEvolution Model: a simple quantitative scaling macroevolution model
PaleobiologyAbstract Scaling fluctuation analyses of marine animal diversity and extinction and origination rates based on the Paleobiology Database occurrence data have opened new perspectives on macroevolution, supporting the hypothesis that the environment (climate proxies) and life (extinction and origination rates) are scaling over the ...

Palaeontology, 2019 AbstractDefinitions of macroevolution fall into three categories: (1) evolution of taxa of supraspecific rank; (2) evolution on the grand time‐scale; and (3) evolution that is guided by sorting of interspecific variation (as opposed to sorting of intraspecific variation in microevolution).

The cultural macroevolution of arcade video games: innovation, collaboration, and collapse [PDF]
Evolutionary Human SciencesArcade video games evolved in a constrained design space, following patterns of diversification, stabilisation, and collapse that mirror macroevolutionary processes.

Testing hypotheses in macroevolution
Studies in History and Philosophy of Science Part A, 2016 Experimental manipulation of microevolution (changes in frequency of heritable traits in populations) has shed much light on evolutionary processes. But many evolutionary processes occur on scales that are not amenable to experimental manipulation. Indeed, one of the reasons that macroevolution (changes in biodiversity over time, space and lineages ...

Simpson's tachytely or bradytely? The importance of quantifying rate uncertainty
Methods in Ecology and EvolutionThe spectacular variation in species forms and richness across space and time can be explored using sophisticated and powerful tools recently developed by evolutionary modellers. In this contribution, we ask if the classic ‘Simpsonian’ view of tachytelic

Inferring Evolutionary Process From Neuroanatomical Data
Frontiers in Neuroanatomy, 2018 Brain evolution has interested neuroanatomists for over a century. These interests often fall on how free the brain is to evolve independently of the body, how free brain regions are to evolve independently of each other, and how different environmental ...

Transitions and multistability in macroevolutionary dynamics of large mammals [PDF]
Acta Palaeontologica PolonicaOn multi-million-year timescales, the climate system of the Earth exhibits complex wandering behaviour. We investigate the evolutionary impacts of long-term climate change by analysing the dynamics of Cenozoic mammal evolution, looking for the presence ...

Modelling singularities in macroevolution
European Economic ReviewMacroevolutionary dynamics often display sudden, explosive surges, where systems remain relatively stable for extended periods before experiencing dramatic acceleration that frequently exceeds traditional exponential growth. This pattern is evident in biological evolution, cultural shifts, and technological progress and is often referred to as the ...

Birds, Bats or Climate? Eucalypt Floral Traits Reflect Pollination Over Abiotic Environment
Ecology and EvolutionFlowers and their traits vary greatly across species, influenced by biotic and abiotic environmental variation. We explore the relative effects of pollination and abiotic environment on flower size and colour in a species‐rich tree clade (eucalypts ...

Navigating uncertainty in maximum body size in marine metazoans
Ecology and EvolutionBody size is a fundamental biological trait shaping ecological interactions, evolutionary processes, and our understanding of the structure and dynamics of marine communities on a global scale.
