Adaptation is a major topic in the philosophy of biology, as it concerns function and purpose . Some biologists try to avoid terms which imply purpose in adaptation, not least because they suggest a deity's intentions, but others note that adaptation is necessarily purposeful.
In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
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.
Over successive generations, the organism must adapt to their surrounding conditions in order to develop their niche. An organism's niche will evolve as changes in the external environment occur. The most successful species in nature are those that are able to use adaptive behaviors to build on prior knowledge, thereby increasing their overall ...
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.
Local adaptation is a mechanism in evolutionary biology whereby a population of organisms evolves to be more well-suited to its local environment than other members of the same species that live elsewhere. Local adaptation requires that different populations of the same species experience different natural selection. For example, if a species ...
Adaptive value is an essential concept of population genetics. It represents usefulness of a trait that can help an organism to survive in its environment.
This adaptation allows for better detection of low-frequency signals. [7] The most likely explanation of the actual transmission of these seismic inputs, captured by the auditory system, is the use of bone conduction; whenever vibrations are applied to the skull, the signals travel through many routes to the inner ear.
