A and B

Answer

Tail

Answer

Backbone

Answer

None of them

Common ancestor population

Descendent

Grandparents

Babies

Question 27

ClownfIsh, Dolphins, and Sharks have similarities and differences in their body structures. What does the information about these structures tell you about the ancestors of these species?

Accepted Answer

All three species share an ancestor population, but Sharks and Dolphins share a more recent ancestor population. This is why they share the live birth structure.

Answer

We cannot make observations of ancestor populations from the past. It is impossible to explain ancestors with only the information about the body structures of different species.

Answer

None share an ancestor population because different species cannot share an ancestor population. It is a coincidence that these species have some of the same body structures.

Answer

Dolphins and Sharks share an ancestor population, but they must not share an ancestor with the Clown FIsh because Dolphins and Sharks give live birth, but Clown FIsh lay eggs.

This sentence is correct.

Answer

A shared structure is a bone in one species that features the same parts.

Answer

A shared structure is the process by which species adapt to environmental changes over a very long time

Question 30

How can you tell if two species are more closely related to each other?

Accepted Answer

The species share a structure that is not shared with the third species.

Answer

The species are both descendants.

Answer

The species are further to the right on the evolutionary tree.

The species share a common ancestor.

Question 31

Penguins, Pigeons, and Hummingbirds have similarities and differences in their body structures. What does the information about these structures tell you about the ancestors of these species?

Accepted Answer

All three species share an ancestor population, but Pigeons and Hummingbirds share a more recent ancestor population. This is why they share the live birth structure.

Answer

Pigeons and Hummingbirds share an ancestor population, but they must not share an ancestor with the Penguins because Pigeons and Hummingbirds have skeletons made of cartilage, but Penguins have hollowed bones.

Answer

We cannot make observations of ancestor populations from the past. It is impossible to explain ancestors with only the information about the body structures of different species.

Answer

None share an ancestor population because different species cannot share an ancestor population. It is a coincidence that these species have some of the same body structures.

Question 32

Which group of descendant species is most likely to have body structures that are the most different from the ancestor population?

Descendant species 1 and 2

Answer

The ancestor population

Answer

It's impossible to say.

Question 33

Which descendant species is most likely to have body structures that are the most different from Descendant Species B?

Descendant Species A

Answer

Descendant Species 1

Answer

Descendant Species C

Answer

Missing information

Question 34

Explain how you know that the Mystery Fossil is related to both whales and wolves.

Accepted Answer

Both whales and wolves have many shared structures, showing that they had a common ancestor.

Answer

There is not enough information to tell that the mystery fossil is related to whales and wolves.

Answer

Whales and the mystery fossil share an ancestor population, but they must not share an ancestor with the wolf because wolves have a nostril on the front of their skull.
