A second possibility is that changes in agonist specificity were advantageous during evolution, i.e. that positive selection acted on some TAAR to recognize ligands other than the known mouse agonists.
Such mutations can be selectively advantageous in evolution or they may cause a change in stability often leading to malfunction and resulting in disease.
Moreover the Tlr7 gene is located on the X chromosome in mammals, which can be advantageous during evolution (e. g. lower polymorphism is maintained by quicker fixation of beneficial mutations and elimination of deleterious ones by stronger selection and more intense genetic drift) [ 90].
The results showed that acid invertase played an important role in biomass allocation and that the physiological responses were beneficial for the high root/shoot biomass allocation, which were advantageous during adaptive evolution to Cu-enriched mine soils.
In biological evolution, advantageous traits provide a reproductive boost to individual organisms.
Although these behaviors were probably advantageous earlier in evolution, they aren't as useful today, with modern stressors that we can't fight or flee, such as work deadlines, Potash added.
This is advantageous for Darwinian evolution.
This may be advantageous to the evolution of Streptomyces.
Such diversity is advantageous in the evolution of an obviously successful family.
Other microsatellites, in contrast, are thought to play an advantageous role in evolution (Kashi and King 2006; Vinces et al. 2009).
In Drosophila, in which it has been shown that Upd acts as morphogen (Xi et al, 2003), maintaining Stat binding flexibility might be advantageous, as the evolution of the number of Stat-binding sites and their spacer length could provide a flexible system to modulate the distance from the source at which a given Stat target could be activated.
