Charles Darwin and Alfred Wallace published simultaneous papers in the subject in 1858, and Darwin subsequently published many additional works on evolution and natural selection.
Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits.

Discover what natural selection theory is, how adaptations work, the story of Darwin's finches and whether we are still evolving.
Sep 25, 2024 · natural selection, process that results in the adaptation of an organism to its environment by means of selectively reproducing changes in its genotype, or genetic constitution. A brief treatment of natural selection follows. For full treatment, see evolution: The concept of natural selection.
Oct 25, 2024 · Evolution - Natural Selection, Adaptation, Genetics: The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation. Experience with animal and plant breeding had demonstrated to Darwin that variations can be developed that are “useful to man.”
Jun 27, 2019 · Advertisement. French naturalist, Jean Baptiste Lamarck, was a pioneer in evolutionary theory who challenged the notion that species were immutable based on fossil records. He argued that traits could be acquired and passed along to the next generation.
