A fossil turtle and a living hawk both have a structure in their neck called the atlas bone. What best explains why both species have an atlas bone?

They inherited this structure from a common ancestor population.

They inherited this structure from separate ancestor populations.

a scientist who studies fossils in order to understand the ancient history of life on Earth.

a scientist who studies weather

a scientist who studies archaeology

A descendant species is:

a more recent species that evolved from an ancestor population.

a older population from which two or more newer species descended.

a related organism from a previous generation

everything that surrounds an organism

An adaptive trait is:

a trait that makes it more likely that an individual will survive in a specific environment

a trait that is a harmful mutation

a trait that always shows up randomly and makes an organism stronger

evidence of life from the past, such as fossilized bones, footprints, or leaf prints

living things, such as plants, animals and bacteria

everything that surrounds an organism

when something stays mostly the same over time

a specific characteristic of an individual organism

a related organism from a previous generation

a more recent species that evolved from an ancestor population

Having died out completely and no longer alive anywhere on Earth

Why do cats and giraffes have similar body structures.

It was a coincidence, that can't happen

They both had the same mother but it was a giraffe

In a dessert where everything looks tan there is the rare animal, "sefolorafouras" if the sefolorafouras had offspring but then one of the babys were pink what would happen?

All of the tan ones will die out.

why did the pawsdoryun get a thicker backbone?

Because of the environmental change.

Why do dogs and wolfs BOTH have a backbone?

A common ancestor passed down the backbone trait

They were best friends and they wanted to mach

They are both common ancestors.

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?

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.

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.

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.

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.

Which of the following situations does NOT explain why one population of descendants look so different from another population of descendants?

Both species stayed in the same environment

Descendant species adapted to their different environments

Both species experienced a barrier in their environment

Is this sentence correct? If not, select the correct sentence: A shared structure is a body structure in two or more species that is identical.

A shared structure is a body structure in two or more species that features the same parts.

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

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

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

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

The species are both descendants.

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

The species share a common ancestor.

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?

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.

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.

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.

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.

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

Descendant species A, B, C, and D

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

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

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

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.

Which species are most closely related to each other?

The species that separated most recently are the most closely related to each other.

The species closest to the common ancestor is more related.

The species that are on the same branch separated most recently.

A population of trout was stable for a long time. Then, their body structures changed to make them smaller. Why did this happen?

Trout were meant to become smaller over evolutionary time.

It is impossible to say without more information.

Their environment must have changed.

The crickets wanted to be louder.
