In addition to what The Bard In Green said, while we know that evolution does happen, there is a lot of debate over what is its main driving force. Darwin argued that the main force was natural selection, and most biologists agree with him. But there are also other schools, such as Kimura’s neutral theory (evolution is caused primarily by luck) and Margulis’s symbiosis theory (evolution is caused primarily by mutualism).
I dont think evolution should be considered just a theory now, its basically proven.
