mutations
gene flow
rewatch skip

Explanation:

Darwin's four principles of natural selection are overproduction of offspring (more offspring are produced than can survive), variation (individuals in a population have different traits), adaptation (some traits are more favorable for survival and reproduction in a given environment), and descent with modification (traits are passed from parents to offspring, and over time, populations can change as favorable traits become more common). Differences is too broad. Mutations are a source of variation but not one of the four main principles. Gene flow refers to the transfer of genes between populations and is not one of the four core principles of natural selection as described by Darwin.

Answer:

descent with modification
