The three natural processes that form the basis for evolution are
Fossils, natural selection and adaptation
Mutation, genetic variation and adaptation
Adaptation, natural selection and inheritance
Predation, genetic variation and natural selection
Definitions / Explanation : Analogous organs & Vestigial or rudimentary organs
$A$ : During evolution pouched mammals of Australia survived.
$R$ : Due to lack of competition from any other mammal due to continental drift
