• It mimics Darwinian natural selection, making "fitness" (as determined by a formula applied to an individual) the chief selector of individuals for survival and procreation, together with mutation.

    它模拟达尔文的自然选择,还有变异,把“适应性”(正如适用于个体的公式所决定的那样)作为主要因素选择生存繁衍和变异的个体。

  • Neutral mutation — Evolution at the molecular level is primarily determined by mutational input and random genetic drift, rather than by natural selection.

    天然突变——演化过程中在分子的层次上主要是经由随机的基因流而决定,并非借由天择所影响。

  • BIOLOGICAL evolution happens by random mutation and selection.

    生物进化是由随机“突变”和“选择”产生的。

  • Strain ZG-24, with high D-xylose reductase activity, was obtained by UV repeated mutation and selection with high xylose concentration plate.

    以此为出发菌株,通过UV重复诱变,并结合高糖平板分离,得到木糖还原酶活力较高的较佳诱变株ZG - 24。
