This is presumed to be adaptive for life in the tiny interstitial openings in sand and soil.
Sometimes violent behavior may be adaptive (for example, in self-defense), in which case the prefrontal cortex will help plan an effective strategy.
It apparently inhabits high elevations, and the moss-like colors of its dorsum may be adaptive for camouflage on moss-covered tree bark.
The researchers suggest that it may be adaptive for a woman with a high-pitched, attractive voice to prefer deep male voices because she may be more able to attract and hang onto a masculine partner than women with lower, less attractive voices.
Furthermore, cross-modal activation of the visual cortex seems to be adaptive for speech recognition.
Reduced lobulation of the lungs is presumed to be adaptive for underwater swimming.
The reproductive early males produced may be adaptive for the deaths of the queens so that the colony will not die and will be able to continue.
Although this result may appear surprising, it may be adaptive for guards to be less sensitive, and presumably more tolerant, to noxious stimuli (see discussion).
Taken together, these changes appear to be adaptive for the surface niche, and the presence of neutrophils, with which Lf would be associated.
However, in this case, the phenotypic plasticity in the absence of the pathogen is likely to result from a resource constraint and not to be adaptive (for a discussion on the adaptive value of phenotypic plasticity, see [19]).
