The theory that was developed based on observations made on the Galapagos Islands is the theory of evolution by natural selection. This theory, proposed by Charles Darwin, is based on his observations of the unique species and variations of animals on the Galapagos Islands. These observations led Darwin to develop the idea that species undergo gradual changes over time through a process of natural selection, where those individuals with advantageous traits for their environment are more likely to survive and reproduce, passing on their traits to future generations.
