As they looked very much like the light-colored trees and lichen
What was the primary consequence of the Industrial Revolution on the peppered moth population?
A shift in the prevalence of light and dark-colored moths
How did the changing environment during the Industrial Revolution affect the peppered moths' survival?
Exposed them to increased predation due to loss of camouflage
What characteristic of peppered moths' coloration made them less likely to be targeted by predators before the Industrial Revolution?
Their resemblance to light-colored trees and lichen
What caused the peppered moths' camouflage to become ineffective during the Industrial Revolution?
The increase in pollution and soot
How did the change in the environment impact the peppered moth population?
The dark-colored moths became more common
What is the primary reason for the peppered moths' coloration?
To camouflage from predators
What is the significance of the peppered moths' name?
It refers to their coloration pattern
What process allowed the peppered moths to adapt to their changing environment during the Industrial Revolution?
Natural selection
Which statement best describes the role of camouflage in the survival of the peppered moths?
Camouflage helped the moths avoid predators
What factor ultimately determined the survival of the peppered moths during the Industrial Revolution?
Their ability to camouflage effectively
Which of the following statements best describes the impact of the Industrial Revolution on the peppered moth population?
The dark-colored moths thrived, while the light-colored moths struggled to survive.
What is the primary mechanism that drove the changes in the peppered moth population during the Industrial Revolution?
Natural selection
What factor primarily determined the survival of the dark-colored peppered moths during the Industrial Revolution?
Their increased camouflage against the soot-covered trees
What term best describes the type of natural selection that occurred in the peppered moth population during the Industrial Revolution?
Directional selection
What factor ultimately led to the recovery of the light-colored peppered moth population after the Industrial Revolution?
The implementation of environmental regulations to reduce pollution
Which of the following statements best illustrates the concept of natural selection?
The peppered moths that were better camouflaged were more likely to survive and reproduce.
What is the primary reason for the peppered moths' name?
Their speckled appearance resembles pepper
Which of the following statements best describes the role of the peppered moth in the context of the passage?
It serves as an example of how natural selection can lead to rapid evolutionary changes.
Study Notes
The Industrial Revolution
- The Industrial Revolution was a time of great change, marked by the replacement of manual labor with machines, increased chemical manufacturing, and the use of new fuels like coal.
- This period, which began in the late 1700s and lasted about 80 years, brought significant improvements to people's lives, including increased earnings, travel, and productivity.
The Peppered Moths
- Peppered moths got their name from their light gray color, which resembled pepper sprinkles.
- Initially, their coloration helped them blend in with light-colored trees and lichen, protecting them from predators.
- The moths' camouflage was effective because they looked very much like the trees and lichen they rested on.
Environmental Impact of the Industrial Revolution
- The Industrial Revolution had severe consequences for the environment, including pollution that killed lichens and covered trees with soot.
- The soot turned the trees black, making the light-colored moths stand out and easy targets for predators, causing their numbers to dwindle.
Natural Selection and Evolution
- Natural selection is the process by which organisms best suited to their environment are more likely to survive and reproduce.
- The Industrial Revolution led to directional selection, where the population of peppered moths shifted from light-colored to dark-colored individuals that blended in better with the dark tree trunks.
- This rapid evolution occurred because the environment changed drastically, making the dark-colored moths more likely to survive and reproduce.
Aftermath
- Since the Industrial Revolution, environmental regulations have been put in place to reduce pollution from factories and other sources.
- As a result, the light-colored moths have made a comeback, and today, they are common once again.
Explore how animals use camouflage to blend in with their environment for survival. Learn about different strategies animals use to avoid predators by staying hidden.
