Detailed explanation-1: -The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct 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 by natural selection is the foundation upon which modern evolutionary theory is built. The theory was outlined in Darwin’s seminal work On the Origin of Species, published in 1859.

Detailed explanation-4: -Natural selection is an inevitable outcome of three principles: most characteristics are inherited, more offspring are produced than are able to survive, and offspring with more favorable characteristics will survive and have more offspring than those individuals with less favorable traits.
