Darwinism

Definition

A theory of biological evolution developed by Charles Darwin, stating that all species of organisms arise and develop through natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Although more commonly associated with evolutionary biology, Darwinism can also influence the study of insect and spider adaptation and evolution in entomology and arachnology.

Etymology

Named after Charles Darwin, the naturalist who formulated the theory.

Example

Darwinism revolutionized the understanding of the diversity of life and the process of evolution.

Synonyms

• Theory of evolution
• Natural selection

Related Terms

• Evolution
• Natural selection
• Adaptation
• Speciation

Usage Notes

Darwinism is often used interchangeably with the theory of evolution, although some modern interpretations include additional mechanisms beyond natural selection, such as genetic drift and gene flow. In entomology and arachnology, its principles help explain the evolutionary processes behind insect and arachnid diversity.
