Sentence examples for Undirected variation from inspiring English sources

While TT scholars generally accept the basic neo-Darwinian framework, they seek to understand variability in artifact traditions largely as outcomes of different cultural transmission systems rather than the strict undirected variation, selection, and drift model favored by the SND group.

In our opinion, the view of directed and undirected variation and their places in evolution presented here diffuses the long-standing tension between the Darwinian and Lamarckian scenarios.

In the first edition of the Origin, he allowed IAC as a relatively unimportant mechanism of evolutionary change that was viewed as subsidiary to random, undirected variation.

Darwin emphasized the evolutionary importance of genuinely random, undirected variation whereas the Lamarckian modality of evolution is centered at directed variation that is specifically caused by environmental factors.

The crucial difference between "Darwinian" and "Lamarckian" mechanisms of evolution is that the former emphasizes random, undirected variation whereas the latter is based on variation directly caused by an environmental cue and resulting in a specific response to that cue.

Most forms of selection reduce the amount of genetic variation within populations, which may be counteracted by the continual emergence of new variation via undirected mutation and recombination.

Second, the undirected generation of heritable variation by mutation and the subsequent non-random sorting of variants by selection are two independent processes.

Evolutionary science, Barash claims, is an "entirely natural and undirected process," involving "random variation plus natural selection".

However, there are also major stochastic and selection contributions given that variation is undirected and unrelated (as far as currently known) to specific environmental cues, so that the fittest variants survive by selection.

Then, we investigate necessary and sufficient conditions for the uniqueness of the reconstruction in both directed and undirected versions, using a parameter k whose variation controls the stringency of the betweenness constraints.

The program also includes a new variation of orderly algorithm for generating undirected graphs.
