Evolution Test 2 Practice (wizer)

Read each statement. Decide it if is an ENVIRONMENTAL FACTOR or an ADAPTATION.

Groups:

(a) environmental factor

,

(b) adaptation

• Horse ancestor has three toes and runs faster to escape from predators.

• Environment is entirely grasslands, with only one or two trees.

• Grasslands begin to appear, with not as many trees to hide behind.

• Horse ancestor has one large toe called a hoof, and quickly out runs predators.

• Horse ancestor has four toes and hides between the trees.

• Wooded areas with many trees to hide behind

Look at the graph. Choose the statement below that best describes what the graph shows.

• Nothing changed in the environment to affect light or dark crabs.

• The environment affected each color equally.

• Something changed in the environment, making the dark crabs the best fit for the environment.

• Something changed in the environment, making the light crabs the best fit for the environment.

Look at the picture. Each layer has a number. Match the numbers of the fossil layers to their age.

• oldest aged layers

• Fossil layers 9-12

• middle aged layers

• Fossil layers 5-8

• most recent layers

• Fossil layers 1-4

Sometimes we see similar fossils that appear in one layer after another, with small changes. Fossils evolve from a common ancestor that lived before them. Look at the picture and then answer the question.

There are round snail-like fossils in layer 3. Which layer did they evolve from?

• layer 2

• layer 4

Remember rock pocket mice that lived on the lava rocks? What will most likely happen to the population at location B, since predators can see the light mice really well now?

• Over time, all of the dark mice on the lava rocks will be eaten.

• Over time, all of the light mice on the lava rocks will be eaten.

• There will be no change.

Look at the data table for finches. How do we know which type of finch is more fit for the environment?

• It is not possible to tell which type of finch is better fit.

• The small beaked finches have increasing numbers, so they are surviving and reproducing because they are a better fit for their environment.

• The large beaked finches have decreasing numbers, so they are surviving and reproducing because they are a better fit for their environment.

Look at the image of the American mastodon and the woolly mammoth, which were drawn from fossils. Then look at the image of the elephant and answer the question.

• The elephant most likely inherited its traits from the woolly mammoth.

• Elephants are the result of artificial selection.

• The mastodon inherited its traits from the woolly mammoth.
