    Evolutionary Explanations of the “Actuarial Senescence in the Wild” and of the “State of Senility” by Giacinto Libertini

    Published 2006-01-01
    “…However, the limits in such capacities are hardly explained in evolutionarily terms by current gerontological theories that rule out fitness decline as something genetically determined and regulated, and therefore somehow favored by natural selection.Four theories are tested as possible explanations of the “increasing mortality with increasing chronological age in populations in the wild” (“IMICAW”[1]), alias “actuarial senescence in the wild”[2], and of the observed negative correlation between extrinsic mortality and the ratio between deaths due to intrinsic mortality and deaths due to extrinsic mortality. …”

    Fetal Programming of Body Composition, Obesity, and Metabolic Function: The Role of Intrauterine Stress and Stress Biology by Sonja Entringer, Claudia Buss, James M. Swanson, Dan M. Cooper, Deborah A. Wing, Feizal Waffarn, Pathik D. Wadhwa

    Published 2012-01-01
    “…We frame our arguments in the larger context of an evolutionary-developmental perspective that supports roles for both nutrition and stress as key environmental conditions driving natural selection and developmental plasticity. We suggest that intrauterine stress exposure may interact with the nutritional milieu, and that stress biology may represent an underlying mechanism mediating the effects of diverse intrauterine perturbations, including but not limited to maternal nutritional insults (undernutrition and overnutrition), on brain and peripheral targets of programming of body composition, energy balance homeostasis, and metabolic function. …”

    The landscape of nucleotide diversity in Drosophila melanogaster is shaped by mutation rate variation by Barroso, Gustavo V, Dutheil, Julien Y

    Published 2023-04-01
    “…Attempts to answer this question have sparked debate about the roles of neutral stochastic processes and natural selection in molecular evolution. However, the mechanisms of evolution do not act in isolation, and integrative models that simultaneously consider the influence of multiple factors on diversity are lacking; without them, confounding factors lurk in the estimates. …”

    PHENETIC ANALYSIS OF POPULUS NIGRA, P. LAURIFOLIA AND P. × JRTYSCHENSIS IN NATURAL HYBRIDIZATION ZONE by A. V. Klimov, B. V. Proshkin

    Published 2018-07-01
    “…In P. nigra, an increase in the diversity of qualitative characteristics and phenotypes was observed in populations confined to hybridization centers. Natural selection is most likely the factor governing the inter-population differentiation in P. × jrtyschensis, leading to the predominance of F1 hybrids in populations and hence to a sharp decrease in inter-population variability.…”

    Cortical areas associated to higher cognition drove primate brain evolution by Marina Melchionna, Silvia Castiglione, Giorgia Girardi, Antonio Profico, Alessandro Mondanaro, Gabriele Sansalone, Narimane Chatar, Alejandro Pérez Ramos, Marcos Fernández-Monescillo, Carmela Serio, Luca Pandolfi, Jacob Dembitzer, Mirko Di Febbraro, Marta Michelle Caliendo, Alessia Di Costanzo, Linda Morvillo, Antonella Esposito, Pasquale Raia

    Published 2025-01-01
    “…Abstract Although intense research effort is seeking to address which brain areas fire and connect to each other to produce complex behaviors in a few living primates, little is known about their evolution, and which brain areas or facets of cognition were favored by natural selection. By developing statistical tools to study the evolution of the brain cortex at the fine scale, we found that rapid cortical expansion in the prefrontal region took place early on during the evolution of primates. …”

    Individual differences in developmental trajectory leave a male polyphenic signature in bulb mite populations by Deere, Jacques A., Smallegange, Isabel M.

    Published 2023-12-01
    “…If, like in mammals and birds where early-life stress effects are extensively studied, we account for such pre-adult viability selection in coldblooded species, it would allow us to (i) better characterise natural selection on trait development like male polyphenisms, (ii) understand how it can affect the response to other selections in adulthood, and (iii) understand how such trait dynamics influence, and are influenced by, population dynamics. …”
