Sentence examples for the ultimate variation from inspiring English sources

The architects of the MS stressed that mutation is the ultimate source of variation, but it is not a proximate cause of evolution (i.e., evolution does not begin with a new mutation), nor an effective agent of change: "mutation merely supplies the gene pool with genetic variation; it is selection that induces evolutionary change" (p. 613 of [ 23]; for further documentation of this view, see [ 34]).

For these three categories, student responses earned a score of two only if they included explicit connections to genetics concepts (e.g., reference to mutations in genes as the ultimate origin of variation [O], inheritance of traits that are genetically determined [I], and change of allele frequencies in populations [P]; see rubric in Table 2).  .

This event is the only time the Ultimate X Challenge variation of the Ultimate X match has been used.

Evolutionary theory has been developed as a tool for investigating the ultimate causes of variation in life history traits and can provide new directions in the search for the proximate (mechanistic) processes.

While mutation is the ultimate source of genetic variation [55], it has been argued that this alone is insufficient to provide the variation to permit major evolutionary advances [68].

Although two-thirds of the guides accurately identified the definition of natural selection, only 25% correctly identified the definition of evolution, and only slightly more than one-third of the guides knew that mutation is the ultimate source of genetic variation.

Although mutation provides the ultimate source of genetic variation, it typically leads to decreased fitness.

Because mutation is the ultimate cause of genetic variation, numerous studies have focused on understanding various aspects of mutation, including estimations of its rate.

Here, size variation is not less important to the ultimate goal than shape variation, and even sequestering it in a separate variable for joint or separate analysis is, at least initially, irrelevant.
