Detailed explanation-1: -Darwin’s book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. The book presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution.
Detailed explanation-2: -The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Detailed explanation-3: -Although Darwin had stated in The Origin of Species that “all the organic beings which have ever lived on this Earth may be descended from some primordial form”, he was keenly aware that there was no explanation of how such an ancestral entity had first evolved.
