Adaptation is one of the basic phenomena of biology. It is the process whereby an organism becomes better suited to its habitat. Also, the term adaptation may refer to a characteristic which is especially important for an...

Definition of adaptation :
In the evolutionary sense, some heritable feature of an individual's phenotype that improves its chances of survival and reproduction in the existing environment.
Unlike evolutionary adaptation which involves transgenerational adjustment, physiological adaptation is generally narrow in scope and involves response of an individual to a particular, usually narrow, range of stimuli.
adaptation
Over the course of time, species modify their phenotypes in ways that permit them to succeed in their environment.
This page is devoted to looking at how evolution leads to adaptation.
adaptation -- Change in a organism resulting from natural selection; a structure which is the result of such selection.
anagensis -- Evolutionary change along an unbranching lineage; change without speciation.
Adaptation changes in the genetics of individuals within a population that make them more fit for their environment

Adaptation: Any change in the structure or function of an organism which makes it better suited to its environment. For example, the torpedo body shape of a tuna allows for fast swimming in the open ocean.
Adaptation: Adjustment to environmental demands through the long-term process of natural selection acting on genotypes.
adaptation Tendency of an organism to suit its environment; one of the major points of Charles Darwin's theory of evolution by natural selection: organisms adapt to their environment.
adaptation
[L. adaptare, to fit]
(1) The evolution of features that make a group of organisms better suited to live and reproduce in their environment.
Adaptation The resetting of the sensitivity level of receptors due to the continued presence of ligands. Also called desensitization.
Adaptations are structures or behaviors that allow efficient use of the environment. For example, the webbed foot of a duck enables it to swim better than a foot that is not webbed.
Adaptations are due to genes, that is, they are inherited.

Adaptation: all organisms adapt to their environments.
Variation: all organisms are variable in their traits.
adaptation An anatomical structure, physiological process, or behavioral trait that evolved by natural selection and improves an organism's ability to survive and leave descendants.
Adaptation is brought about by cumulative natural selection, the repeated sifting of mutations by natural selection. Small changes, favored by selection, can be the stepping-stone to further changes.
Various adaptations provide bacteria with antibiotic resistance. Mutations in a target protein that affect binding of an antibiotic to that protein may confer resistance.
"Koch 62 by mathematical analysis has "shown that in every part of the femur there is a remarkable adaptation of the inner structure of the bone to the machanical requirements due to the load on the femur-head.
The system is based on an adaptation of the best available technology developed by several laboratories.
After the simultaneous inhibition of matrix metalloproteinases, serine/threonine proteases and cysteine proteases in tumour cells undergoing proteolysis-dependent movement, a fundamental adaptation towards amoeboid movement is able to sustain ...
It's that kind of adaptation that allowed some birds to feed on the ground and others to eat fruit from trees. Adaptation is not limited to beaks. It also happened with wings and feet.
C4 photosynthesis is an adaptation for plants living in hot, arid climates.

One of them is by adopting a macrostate denominated spore; another way consists of a biochemical adaptation to that condition by producing proteins that will help her to tolerate higher temperatures.
(1) a waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants.
Another interesting phenomenon is called convergent evolution whereby different species of different ancestry come to resemble one another closely because of adaptation to similar environments.

An adaptation unique to terrestrial plants, the cuticle functions chiefly in the retention of water. As presented in Figure 1, the cells that comprise the epidermis of a leaf are arranged very tightly together in a single stratum.
