|  ||The voyage of HMS Beagle|
The ship HMS Beagle came to the Galápagos Islands on 15th September 1835 and stayed for five weeks.
Its captain was Robert FitzRoy and one of his companions was Charles Darwin. He called the islands a 'land of craters'.
He discovered that many of the: iguanas, finches and giant tortoises on them were unique to the islands and couldn't be found anywhere else in the world. This helped him write his theory of natural selection, explaining how animals gradually evolve or change to make their chances of survival better.
