Two organisms that are closely related would have

completely different DNA sequence

The law of superposition (strata) states

the oldest layer is on the bottom and the youngest is on the top when it is undisturbed

the oldest rock layer is on the top, the younger rock layer is on the bottom

rock layers are always in sequence from oldest to youngest

the youngest rock layer is on the bottom and the oldest is on the top

Scientist find dinosaur fossils in the bottom of a cliff and mammals fossils in the middle layer, what can be inferred?

dinosaurs lived before the mammals

dinosaurs were eaten by the mammals

What would indicate that a series of fossils represent evolution?

the fossils were found in the same layers of rock

the fossils were completely different

What is one reason that strawberries are surviving in the winter season?

they have genetic variations allowing them to be resistant to cold

The tree of life is a metaphor for what idea?

we need water and sunlight to survive

Who was Charles Darwin?

A naturalist who came up with the theory of evolution

A geologist who looked at rocks and fossils

A paleontologist who studied dinosaurs

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.

The diagram represents the relationship between beak structure and food in several species of finches found on the Galapagos Islands. The different beak structures observed in the diagram are evidence of

different species of finches adapting to different environments over many generations

finch species with different beak structures coming to the Galapagos Islands from the coast of Ecuador

finches changing their beak characteristics so that they could feed efficiently

finches mating with birds of other species and acquiring some of their traits

Natural selection is best described as

differences in survival rates as a result of different inherited characteristics

a change in an organism in response to a need of that organism

a process of nearly constant improvement that leads to an organism that is nearly perfect

inheritance of characteristics acquired during the life of an organism

The discovery of DNA and genes proved that

mutations create variations and come from genes

bats and butterflies have a very close common ancestor

Why is the mouse population changing over time?

The hawks eat more light mice than dark mice because they can see the light mice more easily

The light mice can reproduce more successfully than the dark mice

The hawks eat more dark mice than light mice because the dark mice taste better

The hawks eat more dark mice than light mice because they can see the dark mice more easily

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.

Scientists believe horses evolved over a period of 50 million years. How did they change?

Their toes eventually were replaced by a hoof

Their environment changed from a forest to a grassland environment

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

What is the process of which humans breed organisms for certain traits?

inheritance of acquired characteristics

Which of the following is a factor in natural selection?

Individuals of species compete with one another to survive.

All species are genetically diverse.

Individuals better able to adapt to changes leave more offspring.

The fossil record provides evidence that

Older species gave rise to more-recent species.

All species were formed during Earth’s formation and have changed little since then.

The fossilized species have no connection to today’s species.

Starting in 1954, commercial fishers in the northwest Pacific were paid by weight, rather than by the individual fish, for pink salmon. The fishers increased the use of a type of net that selectively catches larger fish. Which of the following effects did this change in fishing technique most likely have on the salmon population over the next 20 years?

The average body size of the salmon population decreased significantly.

The average body size of the salmon population increased significantly.

The average body size of the males in the salmon population increased, and the females stayed the same.

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

changes in genotype, but not phenotype
