Question

darwin noticed that some of the species on the galápagos islands looked similar to species he saw on the mainland of south america. he suggested that ancestors of those species migrated from south america to the galápagos islands and then changed gradually after their arrival. what did darwin call this type of change, when a species diverges from a common ancestor? mutation uniformitarianism natural selection descent with modification

Explanation:

Darwin's theory of evolution includes the concept of descent with modification. When a species diverges from a common ancestor, it undergoes changes over time. Mutation is a source of genetic variation but not the term Darwin used for this overall process. Uniformitarianism is about geological processes. Natural selection is a mechanism within evolution. Descent with modification specifically refers to species evolving from a common ancestor with changes over generations.

Answer:

descent with modification
