Charles R. Darwin

Journey to the Galapagos Islands

Darwin set sail on December 27th, 1831, on the HMS Beagle (a ship), but arrived on the islands on September 15th, 1835. He mainly used this expedition as a way to collect more types of animals for his work back at home, and he was excited about seeing new animals.

Charles Robert Darwin was born on February 12, 1809 in Shrewsbury, Shropshire, England. He went to a boarding school until age 16, when he was taken out of school early by his father. He then went to pursue medical courses with his brother, Erasmus. On October 15th, 1827, Darwin is accepted into college. There, Charles gets in touch with his cousin, who was a beetle collector. His time with his cousin triggered his interest for biology. in August of 1831, Darwin comes back home from Wales, to find a letter inviting him to a trip out to sea, and only after his uncle convinced his dad to let him go, did he accept the offer.

The Life of Charles Darwin

The Creatures of the Galapagos Islands

While on the Islands, Darwin found some new animals, and studied them. One of these new creatures was the "Darwin's Finches." He noticed that different islands had different finches. He also saw how closely the finches were related each kind was, even though their beaks were different. He matched different beaks to diets/foods.

This is an overview of most of the Galapagos Islands.

Lastly, Darwin studied iguanas. He observed both types: marine and land. He also compared and contrasted what they did during the day. Darwin's main question was, "how are they so different, even thought they live on the same islands?"

Darwin also studied tortoises. He mainly studied their shell shapes, their environments, and worked out his hypothesis about the same kind of turtle spreading everywhere.

Natural selection means the changing of DNA in an offspring that might make it more likely to survive. It works by the mixing of DNA with "errors." These "errors" are what make the offsprings not exactly like their parents.
