B
Charles Darwin’s idea of evolution resulting from natural selection.

Explanation: 

Detailed explanation-1: -Definition. The modern synthetic theory of evolution describes the evolution in terms of genetic variations in a population that leads to the formation of a new species.

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: -Charles Darwin’s theory of evolution had three main components: that variation occurred randomly among members of a species; that an individual’s traits could be inherited by its progeny; and that the struggle for existence would allow only those with favorable traits to survive.

Detailed explanation-4: -Julian Huxley coined the term in his 1942 book, Evolution: The Modern Synthesis.
