The theory of evolution has been debated and discussed for many years. It is the scientific process through which organisms undergo changes over time, leading to their ability to adapt to their environment. The term itself has many synonyms, including Darwinism, biological evolution, natural selection, and evolutionism. Darwinism, named after Charles Darwin, implies the belief that all organisms have evolved from previous forms of life. Natural selection involves the process of survival of the fittest, where organisms that are better adapted to their environment have a higher chance of reproduction. Biological evolution encompasses all the changes that have taken place over time, including genetic mutations, while evolutionism refers to a worldview that incorporates evolution into every aspect of life.
