Further, the capacity of [PSI+] to convert previously neutral genetic variation to a non-neutral state may facilitate the evolution of new traits.
Theoretically and empirically it is of interest to know whether gene interactions can facilitate the evolution of diversity.
At the early stages, genome duplication may increase evolutionary rates of duplicated genes21,22 and may facilitate the evolution of a new adaptive function because the original function can be retained in other copies (so-called neofunctionalization model)23,24.
Such variation makes it difficult to design a vaccine that covers the full range of diversity, and could potentially facilitate the evolution of vaccine-resistant parasite strains.
Last but not least, island life is slower than mainland life (ref), and this could facilitate the evolution of a larger brain in island species -- and this larger brain takes longer to develop.
They are generally used to target the innate immune response, which further facilitate the evolution of the adaptive immune response (Pashine et al., 2005; Reed et al., 2009) and mediate the balance between humoral and cellular immunity (Brunner et al., 2010).
In patients with episodic migraine, the presence of psychiatric disorders, such as anxiety or depression or both, facilitate the evolution of the headache into the chronic form [8]. Patients with migraine, anxiety, and chronic depression also had poor health-related quality of life (QOL) [9].
Marples et al., however, showed that dietary conservationism (long-term neophobia) in predators could facilitate the evolution of warning coloration if predators avoid novel morphs for a long enough period of time.
Moreover, high phylogenetic and antigenic distances between vaccines and circulating strains may facilitate the evolution of virulent NDV [75].
If there is a roughly constant mutation rate among phenotypes, then tag based models can facilitate the evolution of cooperation even in well-mixed (non-spatial) populations.
The correlations between Phanerozoic atmospheric oxygen fluctuations and insect body size suggest that higher oxygen levels facilitate the evolution of larger size in insects.
