Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with. genome of an individual organism, and offspring can inherit such mutations.
Fantastically Wrong: What Darwin Really Screwed Up About Evolution. Any theory needs a solid experiment, and that fell to Darwin’s cousin, Francis Galton.

Charles Robert Darwin was an English naturalist. He was born in Shrewsbury, Shropshire. He is famous for his work on the theory of evolution. His book On the Origin of Species did two things.
