A theory of biological evolution developed by Charles Darwin 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. Darwin's ideas have been refined and modified by subsequent researchers, but his theories still form the foundation of the scientific understanding of the evolution of life. Darwinism is often contrasted with another theory of biological evolution called Lamarckism, based on the now-discredited ideas of Jean-Baptiste Lamarck.
Darwinism as modified by the findings of modern genetics, stating that mutations due to random copying errors in DNA cause variation within a population of individual organisms and that natural selection acts upon these variations.
The application of Darwinism to the study of human society, specifically a theory in sociology that individuals or groups achieve advantage over others as the result of genetic or biological superiority.
A structure or habit that results from this process.
An unfolding, opening out, or working out; process of development, as from a simple to a complex form, or of gradual, progressive change, as in a social and economic structure
Advocacy of or belief in biological evolution.
A body of principles that are considered to be inherent in nature and have universal application in determining whether human conduct is right or wrong, often contrasted with positive law.
Natural selection is part of Darwin's theory of evolution saying that those individuals within a species that don't adapt well to their environment will eventually die off, while those that do adapt will continue on with future generations.
A similar model or diagram delineating the development of a cultural feature.
The theory that new species evolve suddenly over relatively short periods of time (a few hundred to a thousand years), followed by longer periods in which little genetic change occurs. Punctuated equilibrium is a revision of Darwin's theory that evolution takes place at a slow, constant rate over millions of years.
The act or process of surviving.
