Rock Pocket Mouse Evolution Flash cards

Front

What is the Valley of Fire known for?

Back

Black rock

Answer explanation

The Valley of Fire is known for its stunning black rock formations, which are a result of ancient volcanic activity. This unique geological feature sets it apart from other landscapes, making 'black rock' the correct answer.

Front

Why does the light-colored fur of the rock pocket mouse stand out on dark lava?

Back

It attracts predators

Answer explanation

The light-colored fur of the rock pocket mouse stands out on dark lava, making it more visible to predators. This lack of camouflage increases the risk of predation, as the mouse is easily spotted against the dark background.

Front

What are the main predators of the rock pocket mouse?

Back

Foxes, coyotes, owls, hawks, and rattlesnakes

Answer explanation

The rock pocket mouse faces predation from various animals, including foxes, coyotes, owls, hawks, and rattlesnakes. Therefore, the correct answer is 'All of the above' as all listed predators pose a threat to this species.

Front

What drives the change in color of the pocket mice population over evolutionary time?

Back

Natural selection

Answer explanation

Natural selection drives color change in pocket mice as individuals with colors that better match their environment are less likely to be preyed upon, leading to increased survival and reproduction of those traits over time.

Front

What gene is responsible for the dark fur color in rock pocket mice?

Back

Mc1r gene

Answer explanation

The dark fur color in rock pocket mice is primarily due to mutations in the Mc1r gene, which affects pigmentation. This gene plays a crucial role in determining fur color, making it the correct choice.

Front

How long does it take for a new mutation to spread and turn the whole population of mice black on a lava flow?

Back

1,000 years

Answer explanation

The spread of a new mutation in a population can take significant time due to factors like genetic drift and environmental pressures. In this case, it is estimated to take about 1,000 years for the mutation to dominate the population.

Front

What is the role of natural selection in how certain plants survive better in their local environment?

Back

It selects the fittest individuals

Answer explanation

Natural selection is the process by which the environment favors the survival and reproduction of the fittest individuals. This leads to the adaptation of species over time, making 'It selects the fittest individuals' the correct choice.

Front

What did Shaniah and Marvin discover about rock pocket mice from different lava flows?

Back

They have different genes for dark color

Answer explanation

The study of rock pocket mice from different lava flows showed that they have different genes for dark color, indicating genetic variation linked to their adaptation to distinct environments.

Front

What does Leah and Marvin's research on rock pocket mice demonstrate?

Back

Evolution can repeat itself

Answer explanation

The evolution of rock pocket mice on different lava flows shows that similar environmental pressures can lead to similar adaptations in separate populations, illustrating that evolution can repeat itself under comparable conditions.

Front

Why is the study of rock pocket mice important for understanding evolution, as discussed by Mickel and Anisha in their biology class?

Back

It provides a clear example of natural selection

Answer explanation

The study of rock pocket mice illustrates natural selection by showing how fur color adaptations help them survive in different environments, providing a clear example of evolution in action.
