Questions & Step-by-Step Solutions

Which of the following is an example of adaptive radiation? (1970)
  • Step 1: Understand what adaptive radiation means. It is when a single ancestor species evolves into many different species that adapt to different environments.
  • Step 2: Look for examples of species that have evolved from a common ancestor and adapted to various environments.
  • Step 3: Consider the finches in the Galapagos Islands. They all came from a common ancestor but evolved into different species with different beak shapes to eat different types of food.
  • Step 4: Conclude that the finches are a clear example of adaptive radiation because they show rapid evolution and adaptation from one ancestor.
