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.

Jun 27, 2019 · The theory of evolution by natural selection is attributed to 19th century British naturalist Charles Darwin. The theory is widely accepted based on fossil records, DNA sequencing, embryology, comparative anatomy and molecular biology. Darwin’s finches are examples of evolutionary adaptation.

Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.

- There have been other theories but they disagree with observations that the theory of evolution through natural selection explains.
Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).

The definition. Biological evolution, simply put, is descent with inherited modification. This definition encompasses everything from small-scale evolution (for example, changes in the frequency of different gene versions in a population from one generation to the next) to large-scale evolution (for example, the descent of different species ...
