non-Darwinian evolutionnicht-darwinsche Evolution (ger.)

  • Long-term transformations of organisms that are not the result of natural selection. (HWB 2011)

    Models of Darwinian and Non-Darwinian Evolution[:] The rate of non-Darwinian change equals the rate of selectively neutral mutation and is independent of environmental fluctuations and of population size. For a given protein, the rate of such change should be nearly constant. Darwinian change, in contrast, is under the influence of changing environment, adaptive radiation, fluctuations in population size, and such facors as adjustment to major changes in the genetic background. Thus it might well be subject to bursts of rapid change in some species and relative stability in others.

    Changes in DNA which are pesumed to result in no selective advantage or disadvantage are the result of what has been termed “non-Darwinian” evolution

    The establishment by “non-Darwinian evolution” of polymorphisms for neutral alleles which may in future combinations or conditions cease to be neutral may provide an important source of genetic flexility that does not impair genetic stability.
