The core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait.
  Charles Darwin proposed a mechanism-called natural selection-for how evolution takes place.   Evolution is the process by which living things become adapted to th â¦ eir environment and new species develop. The idea of evolution was already widely discussed before Darwin but there was no widely accepted mechanism.
