    Evidence of the Complexity of Gene Expression Analysis in Fish Wild Populations by Mbaye Tine

    Published 2017-01-01
    “…The results suggest that the differential expression observed is not the result of evolutionary forces such as genetic drift or adaptation by natural selection. Instead, it can be speculated that genes responded to various abiotic and biotic stressors, including factors intrinsic to animals. …”

    Inactivation of the CMAH gene and deficiency of Neu5Gc play a role in human brain evolution by Yuxin Liu, Jinhong Li, Qicai Liu

    Published 2025-02-01
    “…An inactivation mutation in CMP-N-acetylneuraminic acid hydroxylase (CMAH) was the result of natural selection. The inactivation of CMAH protected our ancestors from some pathogens and reduced the level of N-glycolylneuraminic acid (Neu5Gc) in brain tissue. …”

    Slime-Groove Drag Reduction Characteristics and Mechanism of Marine Biomimetic Surface by Muhan Yan, Yunqing Gu, Longbiao Ma, Jianxing Tang, Chengdong He, Junjun Zhang, Jiegang Mou

    Published 2022-01-01
    “…Improving the energy efficiency of ships not only helps reduce fuel consumption but also reduces carbon dioxide emissions, which is an important guarantee for the green development of the ocean and the maintenance of ecological balance. Through natural selection and adaptation to the environment after evolution, the body surface of organisms generates a variety of ways to resist adhesion and resistance of Marine organisms. …”

    Chronobiology as compensation: can biological rhythms compensate for sexual signals? by Mary L. Westwood, E. Dale Broder, E. Dale Broder, Gabrielle T. Welsh, Robin M. Tinghitella

    Published 2025-01-01
    “…In this perspective piece, we argue that biological rhythms should be considered in the milieu of compensatory traits, as they can reduce the natural selection burden of signaling. This may be particularly true for the many sexual signals that are ephemeral (i.e., only periodically present like a courtship dance). …”

    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. …”
