On the HMS Beagle Darwin explored the world. He left England to Maderia than to South America.

On the ship Darwins job was to collect animal samples. He was also supposed to be the captains companion.

On Darwins 5 year voyage he collected rocks, fossils, plants, and animals. He was also reading a book about how the earth is millions of years old.

Once Darwin arrived at South America he collected even more animals like mockingbirds and finches. As he was collecting he noticed each island had its own variants of animals.

Once Darwin got back home he started re looking his sketches. Darwin and John Gould found that the finches changed after going to the islands.

Darwin also tested artificial selection. He tried breeding pigeons with fan shaped tails to get more like that.

Darwin also looked into natural selection. He found out that some people would be better fit for survival than others.
