Today we’re going to learn about Darwin’s famous voyage aboard the HMS Beagle, but first, let’s get to know Darwin.
Darwin as a child overhead
When Darwin was young, he loved wandering around outside and exploring nature. It was his favorite hob-by. Back in those days, however, very few people were professional scientists.

In fact, most people who studied nature did so as a hobby. The people who typically had the time, money and interest to do this sort of research were clergymen—people in the church. So Darwin went to theology school to become a parson. He did really well in school, but he spent a lot of time with the professors there who were “natural philosophers,” what they called scientists at the time. He also joined a natural history stu-dent group and presented several interesting discoveries. When Captain FitzRoy came to the university and asked one of the science professors to recommend a naturalist willing to join a round-the-world survey group aboard the HMS Beagle, they recommended Darwin.
Voyage overhead
Back then, when you went on a trip all the way around the world, it took a long time. I’m not talking days. It took the HMS Beagle five years to complete its journey. As you go around to each station, notice how long it took for Darwin to travel from one place to the next and how long he spent at each.
Darwin’s voyage on the HMS Beagle is famous because it is the journey on which Darwin collected most of the samples, data and observations that led him to compose his theory of natural selection—the driving force behind evolution. As you go around to each of the stations, you are going to see some of the evidence that he observed and collected. The questions on your worksheet will help guide you through his logic. In our journey today, we’re going to focus on four places where Darwin gathered evidence.
Old Darwin overhead
When Darwin returned home to England, he had gathered a lot of information. For many years he orga-nized and reviewed his specimens, communicated with friends, and thought a lot about what he’d seen. After many years, he developed his theory of natural selection in his mind. However, he did not publish it until he was quite old because he knew his theory would be controversial. On the Origin of Species by Means of Natu-ral Selection, or The Preservation of Favoured Races in the Struggle for Life was published in 1859.
