darwinism

The current paradigm of evolution, which holds that cumulative changes in successive generations of organisms—i.e., evolution of species—results from mutation and natural selection of the organisms that are best adapted phenotypically to survive in an environment—i.e., ‘survival of the fittest’

Darwinism

the theory of evolution formulated by Charles DARWIN that holds that different species of plants and animals have arisen by a process of slow and gradual changes over successive generations, brought about by NATURAL SELECTION. The essential points of Darwin's theory are:
  1. in organisms that reproduce sexually there is a wide range of variability, both within and between species.
  2. all living forms have the potential for a rapid rise in numbers, increasing at a geometric rate.
  3. the fact that populations usually remain within a limited size must indicate a ‘struggle for existence’ in which those individuals unsuited to the particular conditions operating at that time are eliminated or fail to breed as successfully as others (see FITNESS).
  4. the struggle for existence results in natural selection that favours the survival of the best-adapted individuals, a process described by Herbert Spencer (1820–93) in his Principles of Biology (1865) as the ‘survival of the fittest’.

darwinism

the theory of evolution according to which higher organisms have been developed from lower ones through the influence of natural selection.
