adaptive evolution in a sentence

Examples

1. Non-adaptive evolution resulting from the product of mutation and genetic drift is therefore considered to be a consequential mechanism of evolutionary change primarily within small, isolated populations.
2. Eusociality presents an apparent evolutionary paradox : if adaptive evolution unfolds by differential reproduction of individuals, how can individuals incapable of passing on their genes evolve and persist?
3. These genomic methods can also be applied to search for adaptive evolution in non-coding DNA, where putatively neutral sites are hard to identify ( Ponting and Lunter 2006 ).
4. By definition, all genes in a neutral network have equivalent function, however some may exhibit promiscuous activities which could serve as starting points for adaptive evolution towards new functions.
5. During the development of the modern synthesis, Sewall Wright developed his shifting balance theory, which regarded gene flow between partially isolated populations as an important aspect of adaptive evolution.
6. In contrast to mutants that are created in the lab, hopeful monsters have been shaped by natural selection and are therefore more likely to reveal mechanisms of adaptive evolution.
7. The union of traditional neutral theory advanced by Motoo Kimura, have been identified as important causes of genetic diversity, natural selection remains the single primary explanation for adaptive evolution.
8. HyPhy includes a versatile suite of methods to detect adaptive evolution at individual amino-acid sites and / or lineages, including generalizations of Nielsen-Yang PAML and Suzuki-Gojobori approaches and many others.
9. Based on the study, they concluded that post-drought genotypes appeared to be better adapted to shorter growing seasons than the pre-drought genotypes, and that this was a result of adaptive evolution.
10. However, this does not imply that natural selection is always directional and results in adaptive evolution; natural selection often results in the maintenance of the status quo by eliminating less fit variants.
