Detailed explanation-1: -Darwin defined evolution as “descent with modification, ” the idea that species change over time, give rise to new species, and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection.

Detailed explanation-2: -The theory of evolution is a shortened form of the term “theory of evolution by natural selection, ” which was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.

Detailed explanation-3: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-4: -Natural selection is a mechanism (differential reproductive success due to traits) Evolution is a process (change in allele frequencies over time) Natural selection is one mechanism that can lead to evolution.

Detailed explanation-5: -The main difference between Darwinism and evolution is that Darwinism is a theory of evolution based on natural selection whereas evolution is the change in the genetic composition of a population over successive generations. Darwinism describes organic evolution, which results in speciation.
