Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. were there any theories based on it? Yes, Darwin's theory. how is it classified? It can be classified in several different ways, such as by its effect on a trait, on genetic diversity, by the life cycle stage where it acts, by the unit of selection, or by the resource being competed for. what can you tell me about its name?

H. G. Wells [SEP] Introduction
Herbert George Wells (21 September 1866 – 13 August 1946) was an English writer. Prolific in many genres, he wrote dozens of novels, short stories, and works of social commentary, history, satire, biography and autobiography. His work also included two books on recreational war games. Wells is now best remembered for his science fiction novels and is often called the "father of science fiction", along with Jules Verne and the publisher Hugo Gernsback. During his own lifetime, however, he was most prominent as a forward-looking, even prophetic social critic who devoted his literary talents to the development of a progressive vision on a global scale.
