It is the distribution of various species over geographically isolated areas that supports the hypothesis of common descent. For instance, most or even all the indigenous species on geographically isolated islands will bear the closest resemblance to species living on the closest mainland shores, suggesting that they have a relatively recent common origin.
Darwin used the wide variation of beaks to support his theory of evolution. He speculated that all the different finches had descended from one species and were not different species.
Individual organisms differ, but some of this variation is heritable. Species alive today are descended with modifications from ancestral species that lived in the distant past.

Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.

Natural Diversity is the degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystem. Biodiversity is in part a function of climate. In terrestrial habitats, tropical regions are typically rich whereas polar regions support fewer species.

Actually, the rainforest supports the greatest number of species of plants and animals. The grasslands support a greater variety of species than the desert.
The geographic distribution of species around the world supports the theories of evolution by showing patterns of related species found in different regions, suggesting common ancestry and evolutionary processes. This can be seen in biogeographic patterns such as the distribution of marsupials in Australia and South America, which can be explained by continental drift and evolution of species in isolation. The similarities and differences in species within and between regions provide evidence for evolutionary processes shaping biodiversity over time.
The four steps of natural selection are- Overproduction- Variation- inherited Variations- Natural Selection
