The Importance Of Darwin's Trip To The Galapagos Islands

After your recent lecture on Darwin’s theory of natural selection I felt intrigued to go home and research more. When I went to sleep that night, I had a very strange dream about Darwin and his trip to the Galapagos Islands. The Galapagos Islands are a group of islands approximately 600 directly west of Ecuador. They were formed around 5 million years ago by underwater volcanoes. These islands were formed in a similar way to Hawaii, by a hot spot in the Earth 's’ crust. The Galapagos Islands were first discovered in 1535 by Thomas de Berlanga, and they first began to appear in a map in the late 16th century. Also until the early 19th century, the islands were used as a hideout for pirates. Many animals live on the Galapagos Islands including:

He also tells me that he embarked in his journey around the world on December 27, 1831. Throughout his life Darwin was influenced by many scientific theories such as Uniformitarianism and Lamarckism. Uniformitarianism is the ideas the the Earth’s geologic process has operated the same way for the entire history of the Earth. Also, Lamarckism is the idea that organisms have the ability to pass on traits to their offspring. After thinking for awhile, I remembered Darwin’s theory of evolution. According to Darwin, evolution is the ideas of how different organisms have thought to have developed through generations. It also included the idea the the Earth shared a common ancestor. After talking with Darwin for a while, we began to talk about speciation. A species is a group of organisms that share similar characteristics. Many plants of animals of two different similar species from a hybrid. Speciation is a lineage splitting event that produces tw for more new species. It is caused by geographic isolation, and a lack of gene flow between populations. After waking up from this strange dream in the morning you go onto your computer to research more about Darwin’s
