Indeed, one of the authors is quoted as saying: "One possibility is that serious disorders of mood – such as bipolar disorder – are the price that human beings have had to pay for more adaptive traits such as intelligence, creativity and verbal proficiency".
Natural selection is often described as "differential reproduction" of those organisms that have more adaptive traits.
Individual survival under such severe and abrupt disturbances may often be dictated by chance, more than adaptive trait variation, providing a distinction from the more subtle disturbances that have often characterized cases of contemporary evolution in the wild (Hendry et al. 2008).
The study of CAM plants supports the view that morphotypic features generally are less plastic than physiotypic ones (Metlen et al., 2009) with physiotypic plasticity of CAM plants being the more important adaptive trait.
Subsistence producers gave more weight to adaptive traits than did the more market-oriented subsistence + producers.
Instead, goodness might actually be an adaptive trait, allowing more coöperative groups to outcompete their conniving cousins.
These genotypes possess one or more of the adaptive traits required for the flood-prone ecosystem, which range from temporary submergence of 1 2 weeks to long period of stagnant water tolerance.
These cultivars are low yielder but possess one or more of the adaptive traits required for this ecosystem, which range from temporary submergence of one to two weeks, long periods of stagnant water, or daily tidal fluctuations that may sometimes cause complete submergence as in coastal areas.
Regressive features are highly conspicuous in cave-limited organisms, arise frequently across the animal kingdom, and are probably more common than adaptive traits [ 1].
DISCUSSION: G-IRT analyses revealed that nearly all questionnaire items demonstrated clear response patterns, with higher levels of the latent trait corresponding to more adaptive clinical endpoints concerning pain, symptoms, function, and sport activity.
