Two organisms that are closely related would have

completely different DNA sequence

What made Darwin unique when comparing his observations to other scientists of his time when specifically defending his Theory of Evolution?

He explained the mechanism for how evolution happened

He listed his observations in a notebook

He used a logical explanation for all of his observations

He used molecular biology to support his claims

What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland?

There were different types of food available on the island.

There were different types of predators on the island.

The finches had no water to drink.

The finches on the mainland could not fly high enough.

Which of the following is NOT evidence of evolution?

Comparing the migration patterns of animals

Comparing embryological development

Comparing homologous structures

A single species of lizard evolved over time into two species, each on opposite sides of a canyon. This change was likely due to which of the following?

Geographic isolation of the two groups

Low genetic diversity in the initial population

Differences in the reproductive rates of the two groups

High mutation rates on one side

A single species of lizard evolved over time into two species, each on opposite sides of a canyon. This change was likely due to which of the following?

No gene flow between the two populations

Low genetic diversity in the initial population

Differences in the reproductive rates of the two groups

High mutation rates on one side

Which of the following describes members of the same species?

Two groups being able to interbreed to produce fertile offspring

Two groups eating the same kinds of food

Two groups having similar body structures

Two groups having similar embryonic states

Which of the following determines whether or not a variation will become more common in a population?

If the new allele increases the survival rate

If the reproduction rate of the tree frog population remain constant over time

If enough food and water is available in the environment

If the new allele is dominant or recessive

Average beak sizes of the seed-eating medium ground finch on one of the Galapagos Islands are shown in the diagram below. During wet years, all types of seeds are abundant. The medium ground finch prefers to eat small seeds that are easy to crush. However, during droughts (dry years), when small seeds are not as abundant, they eat the larger seeds on the island. How might an extended period of drought influence the ground finch population?

The birds with larger beaks would be more numerous

The birds with smaller beaks would be more numerous

Drought decreases seed availabilty, but has no influence on the ground finch.

Drought increases seed availiability, and all ground finches would be more numerous

The image above shows the changes in a moth population's coloring over time. Which type of natural selection has occurred and why?

Stabilizing selection has occurred because over time the extremes were favored against.

Natural selection because nature selected the trait it liked the best.

Disruptive selection has occurred because over time the extremes were favored against

Directional selection has occurred because over time the population shifted to one of the extremes.

Rock pocket mice species in New Mexico exist as mostly tan in color and easily blend in with the limestone rocks and sand that cover the landscape of this region. About a thousand years ago there was a volcanic eruption which created lava flows on the surface which cooled and turned into a darker black rock color. The rock pocket mice living on the black rocks needed an adaptation to survive against visual predators like hawks and owls. Over multiple generations the population living amongst the black lava flow were observed to change to a black-furred color. Which statement below explains how this might have occurred?

The change of fur color within the population over time happened as a result of a mutation in one or more mice, allowing them to survive and pass along the mutated gene to future generations

Mice fur color cannot change, so they did not survive, rather a new species migrated to this area.

The change of fur color within the population over time became black as a result of the lava flow and allowed the mice to survive.

Mice fur color only changes when exposed to environmental factors such as UV radiation and pollutants.

Geological evidence like fossils can be used as evidence for evolution. Which statements below correctly explain how? Choose all that apply.

The relative age of an ancient organism can be used, based on the order of the rocks.

The absolute age of a fossil can be determined using carbon dating

Comparative anatomy of fossils provide evidence for common ancestry

Rocks contain creatures that have been living since the beginning of time

Charles Darwin observed different species of finches on the Galapagos Island, Which TWO explanations below are correct? CHOOSE TWO ANSWERS.

Finch beaks evolved in response to different food sources on each island.

Different finch species came from a common ancestor in South America.

Finch beaks evolved as a result of the bottleneck effect.

Finch beaks mutated on demand to survive the changing environment.

Different finch species had always existed and had no commoon ancestor.
