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 ...

Macroclimatic Convergence and Habitat Specialisation Shape the Mediterranean Seed Germination Syndrome

Ecology and Evolution
Ecological theory predicts that plant reproductive phenology in the Mediterranean regions is shaped by evolutionary processes driven by strong seasonality in precipitation–evaporation patterns. Thus, it can be expected that seed germination phenology has

Ecological and geographical overlap drive plumage evolution and mimicry in woodpeckers

Nature Communications, 2019
Many abiotic and biotic factors shape the macroevolution of phenotype, but these factors are rarely disentangled across large radiations. Here, Miller et al. investigate plumage evolution across woodpeckers, finding influences of habitat and climate, but

Gouldian Arguments & the Sources of Contingency [PDF]

, 2017
‘Gouldian arguments’ appeal to the contingency of a scientific domain to establish that domain’s autonomy from some body of theory. For instance, pointing to evolutionary contingency, Stephen Jay Gould suggested that natural selection alone is ...

The Fractional MacroEvolution Model: a simple quantitative scaling macroevolution model

Paleobiology
AbstractScaling 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 “megaclimate ...

Putting Process and Product Conceptions of Natural Selection and Genetic Drift to the Test [PDF]

, 2013
This paper argues for two claims. First, despite a persistent appearance to the contrary in the philosophy of biology literature, the question of whether natural selection and genetic drift should be defined as processes or as the products (or outcomes)
