Speciation results in biodiversity.

Explanation:

This phylogenic tree shows the changes in bacterial species from the ancestral species to the most current split in the modern classification system. This tree supports the theory that speciation results in biodiversity. As we know speciation is the terminal source of the latest species, in a similar way, that modification is the terminal source of genetic divergence within species (and extirpation is comparable to lack of alleles). Inequities in the movements of speciation are therefore expected to provide large scale biodiversity exemplars.
