Scientists don't use evolution directly to classify species. The modern taxonomic system predates the theory of evolution by over a century (Linneus, one of the more influential people involved in its widespread acceptance wrote Systema Natureae in 1735 while Darwin didn't come along with The origin of Speciesuntil 1859).
They group species by sets of shared characteristics. However, organisms evolving from shared ancestors also share many of the characteristics from that common ancestor so it ends up correlating with evolutionary paths very closely.
It's probably more accurate to say that evolutionists use taxonomy than the other way around.
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.

We often debate the way a baseball should be thrown or that someone wrote in an article that the way to hold a gun when shooting is THIS way not THAT way.The people who oppose the idea of evolution are those who take the Christian bible literally.Creationism is a religious belief. It says that all life began all at once just a few thousand years ago and has not changed.Evolution says no to that view point. The universe is billions of years old and that things changed slowly over time and organisms adapt to survive in those changing environments.These two will never agree and creationism should be seen in a religious light.
The human foot verses the chimpanzees foot, for instance. Both organisms diverged from common ancestry, but their feet were subject to vastly different environmental pressures and function in very different ways now, though their commonality is rather obvious.
To those who are looking for evidence of intelligent design, all the complex processes of life suggest design. However, they are explicable by evolution. Life has been evolving on the planet Earth for billions of years, which is long enough for complex processes to evolve.
The primary factor missing for billions of years was the development of complex multicellular organisms that could serve as hosts for endosymbiosis. This allowed for the evolution of more complex eukaryotic cells, leading to the emergence of protists.
As populations of organisms evolve, different properties of their cell membranes are selected for or against.
There are billions of organic molecules
The primary factor missing for billions of years was the presence of oxygen in the Earth's atmosphere. The evolution of protists and other complex life forms was made possible by the emergence of photosynthetic organisms like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This oxygenation of the atmosphere allowed for the development of aerobic respiration in organisms, enabling more complex metabolic processes to evolve.

The process of evolution
Evolution is an ongoing process that has been occurring for billions of years and is likely to continue as long as life exists on Earth. It is driven by genetic variation, natural selection, and other mechanisms that enable organisms to adapt to changing environments. While the specific direction and outcomes of evolution are unpredictable, the process itself is a fundamental aspect of life.
