Charles Darwin made a voyage known as, "The Voyage of the Beagel". This is when he went to South America to the Galapagos Islands where he identified new species.

Darwin observed that the finches on the Galápagos Islands had little variations from one population to another. Some finches had sharper beaks, while some had thicker beaks.

Darwin collected birds from the Galapagos Islands and nearby islands. He observed that these birds differed slightly form those on the nearby mainland of South America, and the birds on each island were different from the birds on the other islands; he realized they were all finches! Eventually Darwin suggested that these birds may have _________
