Charles Darwin in 1868. Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states 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.
Universal Darwinism, also known as generalized Darwinism, universal selection theory, [1] or Darwinian metaphysics, [2] [3] [4] is a variety of approaches that extend the theory of Darwinism beyond its original domain of biological evolution on Earth.
In Darwin's own words: "Thus the small differences distinguishing varieties of the same species, will steadily tend to increase till they come to equal the greater differences between species of the same genus, or even of distinct genera." [15] Darwin's tree is not a tree of life, but rather a small portion created to show the principle of ...

Social Darwinism is a body of pseudoscientific theories and societal practices that purport to apply biological concepts of natural selection and survival of the ...
Darwin's theory, originally called descent with modification is known contemporarily as Darwinism or Darwinian theory. Unlike Lamarck, Darwin proposed common descent and a branching tree of life, meaning that two very different species could share a common ancestor.

Darwin was not the first to propose that species of organisms could become modified over time. In the third edition of On the Origin of Species Darwin provided a historical sketch of his predecessors in writing of descent with modification or natural selection, including those whom he had only learned of after the 1859 publication of The Origin.
