Detailed explanation-1: -Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor, which have accumulated gradually over very long time periods.
Detailed explanation-2: -The theory of evolution is based on the idea that all species? are related and gradually change over time. Evolution relies on there being genetic variation? in a population which affects the physical characteristics (phenotype) of an organism.
Detailed explanation-3: -Darwin used multiple lines of evidence to support his theory of evolution by natural selection–fossil evidence, biogeographical evidence, and anatomical evidence.
