Caffeine is a compound found in the seeds of many different plants, such as coffee beans, cola nuts, and cacao beans (the source of chocolate). The presence of this chemical in all three types of plants suggests that these plants

• inherited identical mutations

• share a common ancestry

• were exposed to the same type of radiation in the past

• produced in a lab

The photograph shows a recently discovered all-black penguin chick and several typical black-and-white chicks.

The appearance of this penguin chick with all black feathers might

• increase the types of foods penguins can eat

• decrease the diversity of the penguin population

• decrease the number of variations present in the black penguin population

• result in an increase in black penguins over time if the trait provides an advantage

The photograph shows a polar bear in its environment.

One possible reason why polar bears might not be able to survive if the environment they live in changes is because

• the species will experience decreased competition for mates

• the new environment will cause greater variation in the species

• there will be a larger variety of food sources available

• they are adapted to the specific environment in which they now live

What was the name of Darwin's boat?

• Indefatiguable

• Bugle

• Sloop John B

• Beagle

Which type of adaptation is shown in the image?

Why is the fossil record strong evidence for evolution?

• Because we see changes in fossils over time

• Because the animals in fossils are all extinct

• Because fossils are millions of years old

• Because we see the same animals in fossils as we see today
