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.
