| Anteaters and some whales lack teeth as adults. The presence of teeth in the embryos of these creatures is evidence that |
|
Definition
| these species share a common ancestry with animals that have adult teeth. |
|

| With which of the following statements would an evolutionary biologist agree? |
|
Definition
| Mutations provide the foundation for evolutionary change. |
|

Term
| Which of the following does not have a direct effect on the process of biological evolution? |
|
Definition
| techniques for determining the age of fossils |
|
|
Term
| The evolution of horses shown in Figure 16.6 in the textbook is a good example of the evolutionary process because it |

|
Definition
| All are descended from a common ancestor. |

| Many bizarre plants and animals inhabit the Galápagos Islands, as young Charles Darwin observed when he visited there in the early 1830s. Which of the following is the most likely reason that oceanic islands often have such unusual inhabitants? |
|
Definition
| Islands are isolated and thus susceptible to strong natural selection. |
