2.What caused their differences
Beaks
Food available on that particular island
When the Beagle reached the Galapagos Islands in 1835, Darwin saw a variety of new species, but it was the birds that interested him the most. Darwin noticed that there was a difference between the finches on each of the islands. It seemed their beaks had evolved according to what food was available on that particular island.

A _________ ancestor
__________ into different species
common
evolve
Darwin suspected that the finches had evolved from a common ancestor, which had arrived on the islands a long time before. Over time, it had slowly evolved into many new species. And that was the answer to how new species of plants and animals came to exist: they evolved from earlier ancestors.

It was a completely new idea—a theory of evolution. Darwin explained this theory in his book, On the Origin of Species. It was not published until 1859 and immediately caused a storm. Many people refused to believe that living things, including humans, had evolved from lower forms of life. They were shocked. But Darwin’s scientific studies were so convincing that more and more people started to believe his theory.
