Final answer:
The mockingbirds and tortoises were more closely related to Darwin than the finches.
Step-by-step explanation:
Darwin's finches are a type of bird that Charles Darwin studied on the Galápagos Islands. These finches displayed different beak shapes that helped them acquire specific types of food. While Darwin's finches are well-known, there were two other kinds of birds that were more closely related to Darwin than the finches. These birds were the mockingbirds and the tortoises. Like the finches, these birds also displayed variations in their traits among different islands, providing evidence for natural selection and evolution.
