Adaptation affects all aspects of the life of an organism. [24] The following definitions are given by the evolutionary biologist Theodosius Dobzhansky: 1. Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. [25] [26] [27] 2.
Animals categorized by adaptation or ecological niche; Subcategories. This category has the following 29 subcategories, out of 29 total. ...
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 ...
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.
But the actual effect of climatic adaptation depends greatly on the species in question and often the amount of genetic variability within that species. The bodies of some animals, such as woodrats, are inversely correlated with the mean annual temperature of their environment. [9] This is an applied example of Bergmann's rule
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]
Cuckoos are a canonical example; the female cuckoo has its offspring raised by a bird of a different species, cutting down the biological mother's parental investment. The ability to lay eggs that mimic the host eggs is the key adaptation. The adaptation to different hosts is inherited through the female line in so-called gentes (gens, singular).
Species that possess positive adaptive behaviors will inherently acquire evolutionary advantages. For example, adaptive behavior is a mechanism of population stabilization. [23] In natural communities, organisms are able to interact with each other creating complex food webs and predator-prey dynamics.
