Species make up populations and populations make up communities.
Genetic mutations are the major cause of variation within species. Mutations can introduce new genetic traits that can be passed on to offspring, leading to diversity within a population. Other factors like genetic recombination, migration, and environmental influences can also contribute to variation within species.
Variation within a species is due to genetic diversity, which arises from random mutations, recombination during reproduction, and gene flow from other populations. This variation provides the raw material for natural selection and enables species to adapt to changing environments.
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.
As each new generation is produced, genetic variation may be introduced into a population. The more genetic variation in a population, the more likely it is that some individuals might have traits that will be advantageous if the environment changes.

mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
Genetic variation, which can lead to evoloution, and then potentially a new species.
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
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.
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
