Evolution may be defined as the process of change of characteristic of the organism over generation with respect to time. Charles Darwin is known as the father of evolution.
The species changed over Galapagos island according to the change in the environment. The species that able to adapt and reproduce in that environment are selected by nature. Natural selection acts as the driving force in the evolution of species in Galapagos island.
The Darwin Finches and the Galapagos Turtles have evolved. They now have different traits that help them survive. This is a result of natural selection. Hope that this helped!
