Natural selection. individuals with heritable traits produce more surviving offspring. fitness. In the period from 1860-1900, Darwin developed his theory of natural selection. Natural selection was the idea that a dominant species would overcome all the rest. This sparked many ideas and philosophies, such as a weakening in the church, the rise of Social Darwinism, and a surge of new ideas and thought.- GeeksforGeeks What are Darwin's four Postulates?

He is generally known for his 1859 book " On the Origin of Species ".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.
