There isn't a single scientific name for evolution. "Evolution" itself is the scientific term for the process of change in living organisms over time. It encompasses various mechanisms, including:

* Natural Selection: The process by which organisms better adapted to their environment tend to survive and reproduce more successfully.

* Genetic Drift: Random changes in the frequency of alleles in a population.

* Gene Flow: The transfer of genetic material between populations.

* Mutation: Changes in the DNA sequence.

Therefore, "evolution" is the overarching term, and the specific mechanisms are studied under different scientific names.
