Biology Test 1: Peppered Moth

Questions and Answers

Who is Dr. Kettlewell?

British Geneticist

How did the Industrial Revolution affect the population of the peppered moths in England?

The industrial revolution caused the frequency of dark moths to increase.

What preyed on moths?

Birds

What could have caused the first few moths to change from a light variety to a dark variety?

Natural selection is the cause; light moths were spotted easier by prey, leading to the evolution of darker versions. Signup and view all the answers

Study Notes

Dr. Kettlewell

British geneticist known for studying the peppered moths' adaptation to environmental changes.

Impact of the Industrial Revolution

Industrial revolution increased the frequency of dark 'carbonaria' moths due to pollution.
Light 'typica' moths became more visible to predators, leading to a decline in their population.

Predation on Moths

Moths are primarily preyed upon by birds, which impact their population dynamics.

Causes of Color Variation

Natural selection drove the transition from light to dark moth varieties.
Air pollution darkened tree bark, making dark moths better camouflaged and thus less vulnerable to predation.

Moth Varieties

'Typica' moths: light-colored, typically white, more visible against darkened environments.
'Carbonaria' moths: dark-colored, ranging from brown to black, evolved for better survival.

Survival Strategies of Adult Moths

Adult moths avoid predators by being nocturnal and seeking refuge in trees.
Camouflage plays a critical role in their survival, allowing them to blend into their surroundings based on their color.

Natural Selection Explained

Natural selection is the process by which the fittest individuals survive, reproducing and passing advantageous traits to their offspring.
