The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?

Fossil D is older than fossil C

Fossil A and C are the same age

Fossil B is older than fossil C

Fossils A is older than fossil B

What does genetic variation describe?

differences in the inherited traits of different individuals

similarities in the inherited traits of different individuals

similarities between species in an ecosystem

differences between various species’ mating preferences

How does natural selection drive evolution?

Over time, natural selection causes living populations to evolve environmental adaptations.

It does not; natural selection and evolution are entirely separate processes

Before they can reproduce, individuals must adapt certain traits through natural selection.

Within a generation, natural selection causes populations to eliminate unfavorable traits.

Which of the following is NOT an example of natural selection?

People selectively breeding hamsters.

Insect populations developing resistance to certain pesticides.

Bacteria becoming resistant to antibiotics.

Male birds of certain species developing colorful feathers to attract female mates.

Two organisms that are closely related would have

completely different DNA sequence

Birds are eating all the green beetles. Because the brown beetles are surviving they reproduce more and make more brown beetles. This is called ___________

The Theory on the Origin of Species

Why were the beaks on Darwin's finches so Important?

They show that the finches adapted to their environments. Their beak shape matched the food available on each island.

They showed the finches always existed as Darwin found them.

They showed that the finches could mutate their beaks whenever they want.

They showed variability in the finches species. All finches were equally adaptable to all islands.

4. When the industrial revolution started, the trees have been covered in soot from coal factories. Which moth will be more successful in this environment?

Both are Equally Successful in this Environment

Why could the same species of moth be two different colors?

Their color was based on their DNA. Sometimes a mutation would cause the moth to be born with a different color.

Their color was caused by the environment. The soot from the factories would fuse with the moth's skin.

Bacteria inside the moth's stomach would sometimes give the moth stomach the ability of the moth to have "active camouflouge." This allowed the moths to change their color at will.

If scientists find fossils of a type of mosquito on the bottom layer and find fossils of beetles towards the top layer, what can scientists infer?

Mosquitos are older fossils than beetles

Beetles are older fossils than mosquitos

Both mosquitos and Beetles must have lived at the same time.

When we examine this whale fossil, we can see that the whale has a pelvic bone that doesn't seem to be used by the whale. What do scientists infer?

The whale had an ancestor with legs

The whale must use the pelvis for an unknown reason

The whale was born with an extra bone and has a disorder

The whale had an ancestor with wings

Why are homologous structures important to the theory of evolution?

Scientists use them as evidence that many species must have had a common ancestor.

Scientists use them as evidence that many species must have independently evolved and are not related to other species.

Scientists use them as evidence to show that all kinds of structures in our bodies work to help us survive.

How do scientists use embryology to support the theory of evolution?

Embryos of many species have a lot of similar characteristics when they are first forming showing different creatures must have a common ancestor

Embryos of many species have very little in common until they start developing for long periods of time

Features like gills and tails prove that all animals are really just fish

Which statement supports the theory of natural selection

Over time advantageous traits will be found in more of the population.

All organisms produce more offspring than can survive.

Organisms live in harmony with one another despite limited resources.

Organisms with favorable traits are more likely to die.

Which fact provides the best evidence for the biological theory of evolution?

Characteristics of simpler life forms can be found in more complex life forms.

Most fossils are found in sedimentary rock.

Most species of life on Earth have become extinct.

Only a small percentage of living things have been preserved in fossils.

What will most likely happen if a species can no longer produce offspring?

It will evolve into another species.

It will move into a new environment and adapt.

It will begin to mutate into another organism.

A student made a table showing different types of finches and their food sources. What can be inferred from this information?

Organisms evolve based on their feeding habits.

Genetic mutation leads to the evolution of new species.

Organisms evolve based on their habitats.

Geographical isolation leads to the evolution of new species.

Dark moths began to outnumber white moths in cities after the Industrial Revolution. What is the most likely reason for this change?

Light-colored moths were less favored for survival in the new environment.

Light-colored moths mutated into dark colored moths.

Light-colored moths began to die due to overpopulation.

Light-colored moths began to turn black because of factory pollution.

The numbers in the diagram represent the first three months of spring in a grassland environment. The bird is carnivorous and eats mice for survival, and the mice depend on the seeds from the grasses. Which explanation best describes what is happening in the diagram?

The dark phenotypic variation of the mice provides an advantage that allows the dark-colored mice to survive and reproduce.

A disease affecting the carnivorous bird population results in the decreasing numbers of birds and the increasing numbers of mice.

A disease reaches epidemic proportions resulting in a decrease in the mice population in the grassland.

The dark phenotypic variation of the mice makes the dark-colored mice more visible to their predators so they are more likely to be eaten.

What role does genetic variation play in the evolution of species?

It increases the chance that species will possess characteristics well-suited for a changing environment.

It reduces the chance that species will possess characteristics well-suited for a changing environment.

It allows multicellular organisms to change their traits during their lifetimes.

It allows unicellular organisms to change their DNA after they die.

This insect has adapted a unique shape and appearance as shown in the diagram. What led to the development of this adaptation?

the need to increase its ability to hide from predators

the need to increase its surface area to reduce water retention

the need to increase its ability to fall long distances without harm

the need to increase its ability to hunt smaller insects
