Sentence examples for timescale selection from inspiring English sources

Though the neo-Y is degenerating at a breakneck pace on an evolutionary timescale, selection pressures are still felt (Genome Biology and Evolution 10.1093/gbe/evr103).

Over evolutionary timescales, selection for female discrimination against diploid males is therefore likely to depend on the frequency of population bottlenecks and concomitant variations of the proportion of diploid males.

As with many economically important woody perennial species, breeding of Ribes is a long-term process due to the highly heterozygous germplasm available and the long generation time, so there is an obvious incentive to develop marker-assisted breeding strategies to reduce the timescale for selection of superior genotypes.

We expect that in natural communities, adaptation to newly encountered microparasites or changes in microparasite virulence occurs on ecological rather than evolutionary timescales, necessitating selection based on pre-existing genetic variation, referred to as 'standing genetic variation' (Barrett and Schluter 2008).

These processes are active early in development and influence phenotypes throughout the lifespan, maintaining or enhancing fitness on a timescale intermediate between selection and homeostasis.

But, without putting any timescale on the selection process, Moxey and owner Steve Morgan are handing the initial responsibility to Kevin Thelwell, promoted from academy manager to head of football development and recruitment in December.

However, most will be lost on an evolutionary timescale as negative selection and genetic drift act on deleterious and neutral motifs respectively.

However, due to a paucity of data regarding the deeper evolutionary history of angiosperms and the short timescale of human selection, adaptive potential, rather than evolutionary potential, is more readily apparent at present.

Such variation over sufficient timescales may initiate selection processes in certain loci.

In both cases, the resulting 'random' individual mutants (Darwinian variations) are tested by physicochemical and biological environments for short-term viability ('staying alive') and for reproductive competence leading to heredity (ancestry, lineages) on evolutionary timescales (Darwinian natural selection).

Persistence of a mitochondrial polymorphism on such a deep evolutionary timescale suggests that balancing selection may be shaping mitochondrial sequence evolution in oniscid crustaceans.
