Scientists compare the limbs of organisms to look for evidence of common ancestry. These limbs provide evidence of common ancestry because they -

• perform the same function
• are the same size
• have the same basic structure
• are parts of the same animal

The Galapagos Islands, a small group of islands off the coast of Ecuador, is home to reptiles such as the giant tortoise and the iguana. The eastern islands are much older than the islands to the west.  Which statement about the origin of these reptiles is best supported by this information?

• The ancestor of each species came from different continents at different times.
• The common ancestors of the reptiles probably came from Equador.
• The common ancestor of each species evolved in Peru and came to the islands at the same time.
