Natural selection.
There's no such thing as an "evolution scientist". There is, however, such a thing as an evolutionary biologist. Evolutionary biology encompasses all research into the evolutionary processes that shape life. This includes an extremely wide variety of activities, which is difficult to summarize in a few words.

The model for the slow ongoing process of evolution is called gradualism. It suggests that evolutionary change occurs gradually over long periods of time through the accumulation of small, incremental changes in populations. This contrasts with punctuated equilibrium, which suggests that evolution occurs in short bursts of rapid change followed by long periods of stability.
Natural selection acts as the mechanism by which certain traits become more prevalent in a population over time, leading to evolutionary changes. It promotes the survival and reproduction of individuals with advantageous traits, while individuals with less favorable traits are less likely to reproduce. This process drives the adaptation of organisms to their environment, ultimately shaping the evolution of species.
Character displacement in biology refers to the evolutionary process where similar species that occupy the same ecological niche develop differences in traits to reduce competition for resources. This contributes to evolution by promoting the diversification of species and the formation of new species over time.
Classification is the organization of organisms into groups based on shared characteristics, while evolution is the process by which organisms change over time. Classification reflects the relatedness of organisms based on their evolutionary history, with closely related organisms grouped together. Evolutionary relationships between organisms can provide insights into their classification and help refine the existing classification system.
The evolutionary process that produces analogous structures is called convergent evolution. Convergent evolution refers to the independent evolution of similar traits in species that are not closely related, usually in response to similar environmental pressures.

Speciation is the evolutionary process by which new biological species arise.
Evolutionary adaptation refers to the process of organisms changing over time in order to remain alive. This evolution is a theory of natural selection.
You could be thinking of evolution
Evolution is the result of a process called survival of the fittest. Genes are part of the mechanism by which this happens.
The evolutionary theory is currently apprised of many different aspects. One of the biggest things is that evolution happens through natural selection and survival of the fittest.
Evolution continues for a basic reason: time does not stop. The progression of time itself is an evolutionary process. Over a long period of time, this process can undergo genetic changes and manifestations for various biological, ecological, or physiological reasons.
Evolution is a process in which something passes by degrees to a different stage, especially a more advanced or mature stage. In biology it is the sequence of events involved in the evolutionary development of a change in a species. All living things are capable of evolution.
Evolutionary prototype, when built, forms the heart of the new system, and the improvements and further requirements will be built.When developing a system using Evolutionary Prototyping, the system is continually refined and rebuilt.Evolutionary Models take the concept of "evolution" into the engineering paradigm. Therefore Evolutionary Models are iterative.
The end result of the evolutionary process is not predetermined or fixed. Evolution is an ongoing process driven by changes in genetic variation and natural selection over time. Organisms continue to adapt to their environments, so there is no final endpoint or ultimate form that all species are moving towards.
The evolutionary software process model involves working with the customers. It starts by specifying clear requirements of the software and features suggested by the customer are added later during development.
