Jan 1, 2021 · The “selection” process is “natural” in the sense that it occurs without any conscious intervention (there is no “selector”) in response to an ongoing “struggle for life.”. Traits and characteristics favorable to survival in that struggle are preserved and developed. This, for Darwin, is the basis of evolution. Ever since Charles Darwin published the theory of evolution by natural selection in 1859, myths and misinterpretations have eroded public understanding of his ideas.

Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Oct 13, 2023 · Natural selection, process in which an organism adapts to its environment through selectively reproducing changes in its genotype.
