Many aspects of an animal or plant can be correctly called adaptations, though there are always some features whose function remains in doubt. By using the term adaptation for the evolutionary process , and adaptive trait for the bodily part or function (the product), one may distinguish the two different senses of the word.
Neural adaptation or sensory adaptation is a gradual decrease over time in the responsiveness of the sensory system to a constant stimulus. It is usually experienced as a change in the stimulus. For example, if a hand is rested on a table, the table's surface is immediately felt against the skin.
Animals categorized by adaptation or ecological niche; Subcategories. This category has the following 29 subcategories, out of 29 total. ...
There are many environmental examples of sexual selection as an adaptive behavior; one popular example is sexual dimorphism. Sexual dimorphism is a morphological, phenotypic difference between males and females of the same species. [20] A common example of sexual dimorphism is difference in body size. [20]
A psychological adaptation seen universally in humans is to easily learn a fear of snakes. [1] A psychological adaptation is a functional, cognitive or behavioral trait that benefits an organism in its environment. Psychological adaptations fall under the scope of evolved psychological mechanisms (EPMs), [2] however, EPMs refer to a less ...
Adaptationism is an approach to studying the evolution of form and function. It attempts to frame the existence and persistence of traits, assuming that each of them arose independently and improved the reproductive success of the organism's ancestors.
Individual selection acts on the individual, in the sense that adaptations are "for" the benefit of the individual, and result from selection among individuals. Gene selection acts directly at the level of the gene. In kin selection and intragenomic conflict, gene-level selection provides a more apt explanation of the underlying process.
A unique and complex example of plasticity is camouflage, an adaption that allows animals to avoid predators by hiding in plain sight. [14] The mechanisms behind camouflage are not the same in all species - they can be morphological, physiological, behavioral, or even a combination of traits. [ 15 ]
