Evolution of the Peppered Moth: A Case Study P1

What color variations do peppered moths exhibit?

• Black and white

• White with dark spots and dark with light speckles

• Green and yellow

• Red and blue

Which moth coloration had a survival advantage in natural, unpolluted environments?

• Dark-colored moths

• Light-colored moths

• Neither had an advantage

• Both had equal advantage

What major event led to a change in the survival advantage of moth colorations?

• The Industrial Revolution

• The digital revolution

• The invention of electricity

• World War II

How did pollution from the Industrial Revolution affect the trees and the moths?

• Trees became taller, providing more hiding spots for moths

• Pollution had no significant effect on trees or moths

• Trees were coated in dark soot, giving dark-colored moths an advantage

• Trees changed color to green, benefiting light-colored moths

What happened to the population of dark-colored moths during the Industrial Revolution?

• It remained the same

• All dark-colored moths mutated to light-colored

• It decreased significantly

• It increased due to their camouflage

What measures were taken to address air pollution?

• Moths were relocated to pollution-free areas

• Pollution was ignored

• Emissions were reduced through laws

• Factories were closed permanently

After reducing air pollution, which moth variation became more common again?

• A new color variation emerged

• Both were equally common

• Light-colored moths

• Dark-colored moths

What principle does the change in moth population illustrate?

• Genetic mutation

• Natural selection

• Artificial selection

• Social Darwinism

How did the environment influence the survival of the peppered moth?

• Only predators influenced survival

• The moths adapted by changing their diet

• It had no influence

• Changes in the environment directly influenced which coloration had a survival advantage

What does the story of the peppered moth demonstrate about evolution?

• It is a slow process taking millions of years

• It disproves the theory of natural selection

• It cannot be influenced by human actions

• It shows how species can quickly adapt to environmental changes
