Morphometric variation of extant platyrrhine molars: taxonomic implications for fossil platyrrhines [PDF]
PeerJ, 2016 The phylogenetic position of many fossil platyrrhines with respect to extant ones is not yet clear. Two main hypotheses have been proposed: the layered or successive radiations hypothesis suggests that Patagonian fossils are Middle Miocene stem ...

Meta-analysis Shows That Rapid Phenotypic Change in Angiosperms in Response to Environmental Change Is Followed by Stasis [PDF]
The American Naturalist, 2019 The amount and rate of phenotypic change at ecological timescales varies widely, but there has not been a comprehensive quantitative synthesis of the patterns and causes of such variation for plants. Present knowledge is based predominantly on animals, whose differences with plants in the origin of germ cells and the level of modularity (among others ...

A new explanation for unexpected evolution in body size. [PDF]
PLoS Biology, 2017 Bigger is apparently frequently fitter, and body size is typically heritable, so why don't animals in wild populations evolve towards larger sizes? Different explanations have been proposed for this apparent "paradox of stasis." A new study of snow voles

Zebrafish as model system for the biological characterization of CK1 inhibitors
Frontiers in Pharmacology, 2023 Introduction: The CK1 family is involved in a variety of physiological processes by regulating different signaling pathways, including the Wnt/β-catenin, the Hedgehog and the p53 signaling pathways. Mutations or dysregulation of kinases in general and of

Selection and drift determine phenotypic stasis despite genetic divergence [PDF]
, 2019 1AbstractEvolutionary theory suggests that phenotypic stasis is explained by natural selection and genetic drift, or by constraints imposed by mutation and recombination of standing genetic variation. We performed experimental evolution from standing genetic variation with the nematodeCaenorhabditis elegans, measuring individual locomotion in ...
