Botany and Zoology
During his college years at Cambridge Charles Darwin had an interest in botany and zoology. Mainly collecting different beetles. In his autobiography he wrote a passage about a time when he saw two rare beetles and grabbed both of them. Then he saw a third beetle he hadn't seen yet. He put one beetle into his mouth which it ejected acid into his mouth causing him to spit it out and lost both beetles. “Home.” Famous Scientists, www.famousscientists.org/charles-darwin/. -
The Beagle Voyage
Charles Darwin embarks on a five year journey with a survey team stopping at South America, Galapagos Islands, and Australia. During this journey he examined and collected samples of fossils, flowers, and rocks. At the Galapagos Islands he observed a species that each island had its own version of. Where he later concluded that these birds had all one single descendent.

Theory of Evolution (Natural Selection)
After his long voyage he began thinking of how all the plants and animals he encountered could have changed. He decided that the species would "transmute" to over generation to fit their environment. It would pass on the favorable variation and the unfavorable ones would be destroyed. The bird that he observed on his travels was the finch. On each island its beak had a different shape to match each food type it was going for.

The Origin of Species
Darwin released a book on November 24, 1859 called "The Origin of Species." It is known as one of the bot important biology books in existence. In this book he released all of his findings for his Theory of Evolution. However, he did avoid making any claims about the origin of human beings. Where he spent the rest of his days updating and editing the book further for more findings. “Charles Darwin: Gentleman Naturalist.” Darwin Online, darwin-online.org.uk/darwin.html.
