The variation within a species are the tiny to significant differences which have evolved over time. Insects which live in Africa have features which allow them to survive the heat better than those living in Antarctica.
This term also means biodiversity. Not all individuals within a species are exactly the same. They are not clones of each other.

Variations among members of the same species is an expression of traits. Traits are a result of the genes you receive.
mutations
The genetic variation enable a particular species to withstand the adversities of Nature by way of selection on the basis of the principle of survival of the fittest.
Biodiversity means the degree of variation of life. Some examples would be genetic variation in a species or ecosystem variation in a planet.
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
It promotes genetic variation.
Sexual Reproduction Genetic mutation
Human species, as in the variation in height.
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
Genetic variation, which can lead to evoloution, and then potentially a new species.
Variation within species can be caused by genetic mutations, environmental factors, and interactions between genes and the environment. Genetic mutations are changes in the DNA sequence that can create new traits. Environmental factors, such as diet and climate, can also influence variation by selecting for certain traits over others.
Intraspecific variation
Sometimes positive variation can improve some ability of the species adapted to the environment. For example, a kind of virus can be killed by medicine A. A small part of the virus has some variation that make it can be alive with medicine A. The species of the virus can exist in future, or it will disappear in the future in the environment full of medicine A. Besides, positive variation can provide some capacity for the species to get more resource in the competition. Of course, there is negative variation that might contribute to the disappearance for the species. That is just another side of variation.
Sometimes it is very hard to distinguish between a species where there is a lot of variation between that of a variation that is actually two separate species. Many times scientist disagree on how to tell these two things apart.
Gentic variation is mearsured by the number of species in the given area not.
variation
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
