S.A. From there we hopped an island charter and flew the 600 miles to the island of San Cristobal, Galapagos to board the Galapagos II live-aboard for 7 days. The crew is polished to perfection and is there to satisfy your every whim. Meals are delicious and nutritious, and warm cakes, brownies and lemonade await you as you immerge from your dives. Charles Darwin came to the Galapagos Islands in 1835 and it was after his return to England that he proposed his theory of evolution. This theory stated that life is the result of billions of years of adaptations to changing environments.
Natural selection is another way of putting it.
If these characteristics can be passed onto offspring, then the offspring will have the same advantages. As the environment changes, so will the appearance of these individuals from their original version. They will do better, live longer, and produce more offspring until they eventually are classified as a new species. This new species with the changing environment will favor new characteristics over the old ones. The Galapagos consist of 19 islands and 42 islets or surfacing rocks.
