Charles Darwin was a the man who studied evolution. One theory he came up with was the survival of the fittest. Which means that only the strong specie will survive and the weak ones will die off. Along with adaptation to natural environments, he wrote a famous book about this called "Origins of the Species" in 1859.

Charles Darwin's book that caused the most controversy was "The Origin of the Species". He had worked on the theory of natural selection for many years, but the book was released in 1859.

Darwin's theory of evolution primarily consists of four key components: variation, inheritance, selection, and time. Variation refers to the differences in traits among individuals in a population. Inheritance is the passing of these traits from parents to offspring. Selection involves the process where certain traits become more common in a population due to their advantages in survival and reproduction, while time accounts for the gradual changes in species over generations through these mechanisms.
