He found fossils of animals with very large bones similar to animals of his time. Where did they go? Over 1.7 million species of organisms live on Earth today.

Galapagos Organisms : 

Galapagos Organisms The islands are about 1000 km from the western coast of South America near the equator. There are 13 large islands, 6 smaller ones, and 107 islets. Ruled by the Province of Ecuador inhabited by about 15,000 people. He encountered giant tortoises, large iguanas with very big claws, as well as finches with different shaped beaks. He wondered why these organisms had different characteristics from those he saw on the mainland?? He concluded they developed adaptations, or traits which help the organisms survive.
