ADAPTATION- It is the change in the physical appearance and/or the physiological characteristics of an organism upon exposure to different conditions of environment generally the harsher ones ( such as temperature, radiations and the nutrient sources ) . Gradually the immune system of an organism gets acquainted to the new environment and hence it is said to be adapted.
VARIATION- The transmittance of the adaptation to off springs results in new family of a species known as variants . The phenomenon of the generation of a new variant of a species is known as variation .
ADAPTATION is the source of VARIATION.
For examples if you look at the various breeds of canines ( dogs) in the world, they vary though they belong to the same species , this is because of their adaptation to the different prevailing climatic conditions.
The transfer of adapted features such as longer furs (canines in cold climates) and the modified hooked beaks in birds is due to the transfer of adapted traits from the parents to off springs through the vehicles of heredity known as DNA .
The passing on of the adapted traits to the off springs i.e. variation over an observed period is called as the EVOLUTION of a new variety or EVOLUTION .
Adaptation does not allow for natural selection: natural selection causes adaptation.
Adaptation (I'm studying the same thing ;)
Its a chicken and egg situation. Adaptation is the response to Natural Selection, and Natural Selection is the response to Adaptation. They both operate by the principle: the members of any species that are best adapted to their environment are the ones most likely to survive and reproduce the next generation, where the process repeats. That does not mean the strongest or most aggressive, they often get themselves killed off.
Natural selection is most closely related to Darwin's theory of evolution.

Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
Adaptation does not allow for natural selection: natural selection causes adaptation.
Natural selection is what causes adaptation.
Because adaptation is the directly visible result of natural selection.
Here is a quote: "The relationship between adaptation and natural selection does not go both ways. Whereas greater relative adaptation leads to natural selection, natural selection does not necessarily lead to greater adaptation." I do not recall who said it, but this is what the relationship between both is. Here is a quote: "The relationship between adaptation and natural selection does not go both ways.

No, it's exactly the other way around: natural selection causes adaptation.
Adaptation is changes in the overall physiological makeup of a population of organisms that bestow increased reproductive fitness on the population. Natural selection causes adaptation by favouring variants with increased reproductive fitness over less reproductively successful variants.

Natural selection.
Natural Selection.
Adaptation is a trait that helps an organism survive and reproduce in its environment, while natural selection is the process by which organisms with advantageous adaptations are more likely to survive and pass on their genes to the next generation. In other words, adaptation is the result of natural selection.
