non- +‎ adaptive


  • The remaining three evolutionary forces are nonadaptive in the sense that they are not a function of the fitness properties of individuals: mutation is the ultimate source of variation on which natural selection acts, recombination assorts variation within and among chromosomes, and genetic drift ensures that gene frequencies will deviate a bit from generation to generation independent of other forces.

    A Disclaimer for Behe?

  • Can specialization, in the extreme be nonadaptive?

    Ricardo's Difficult Idea Eludes Wonks, Arnold Kling | EconLog | Library of Economics and Liberty

  • A lot of his recent work has been on nonadaptive processes and genomic architecture, and it has led him down some interesting paths.

    Another predictable argument against front-loading

  • One of my favorite biologists, Michael Lynch, had a very interesting thing to say about the evolution of multicellularity recently: that it may have come about via nonadaptive means.

    Another predictable argument against front-loading

  • Shtulman doesn't use the term 'vitalism' but transformationism as he characterizes it involves the following characteristics: 1. Variation: Individual differences are nonadaptive or maladaptive deviations from type.

    Intuitive Essentialism (IV)

  • Seilacher then argues that most manifestations of the pattern are probably nonadaptive.

    Wolfram online

  • This means that the presence of group selection or the effectiveness of group selection is to be measured by the existence of nonadaptive behavior on the part of individual organisms along with the presence of a corresponding group-level adaptation.

    Units and Levels of Selection

  • Wallace's hyperselectionism can be seen in his belief that every trait must have an adaptive purpose (owing to natural selection), a view that caused him to reject much of Darwin's theory of sexual selection, developed by Darwin to explain seemingly nonadaptive traits like the peacock's tail.

    Darwin and His Doppelgänger

  • Population genetics has worked out in theory, and validated in practice, an elegant, mathematical account of the large role that neutral, and therefore nonadaptive, changes play in the evolution of nucleotides, or individual units of DNA programs.

    Darwinian Fundamentalism

  • Natural selection does not explain why many evolutionary transitions from one nucleotide to another are neutral, and therefore nonadaptive.
