Charles Darwin observe the plants and animals on his voyage to which of the following locations?

• The Galapagos Islands

• South America

• Hawaii

• The South Pacific

Darwin noticed that finches on different islands had uniquely shaped beaks. Which of the following best describes why he felt this had occurred?

The Law of Superposition states that

• Older rock layers are found above younger rock layers, therefore fossils found in shallower rock are most likely younger than those found below them

• Younger rock layers are found above older rock layers, therefore fossils found in shallower rock are most likely younger than those found below them

• Older rock layers are found above younger rock layers, therefore fossils found in shallower rock are most likely older than those found below them

• Younger rock layers are found above older rock layers, therefore fossils found in shallower rock are most likely older than those found below them
