What is the significance of the Industrial Revolution on peppered moths?

Back

The population of peppered moths changed from light to dark because light moths were easily seen against sooty trees and were eaten by predators.

Front

What is Geographic Isolation?

Back

Geographic Isolation occurs when a species is separated by physical barriers, leading to the development of unique traits in different environments.

Front

What are Genetic Mutations?

Back

Genetic Mutations are changes in the DNA sequence that can lead to variations within a species.

Front

What is an example of Natural Selection?

Back

Insect populations developing resistance to certain pesticides is an example of Natural Selection.

Front

What is NOT an example of Natural Selection?

Back

People selectively breeding hamsters is NOT an example of Natural Selection.

Front

What is the outcome of Natural Selection?

Back

The outcome of Natural Selection is that better adapted organisms survive and pass their traits to their offspring.

Front

What is Variation in the context of Natural Selection?

Back

Variation refers to the differences in traits among individuals in a population, which can be caused by genetic mutations.

Front

How does Natural Selection lead to Evolution?

Back

Natural Selection leads to Evolution by favoring traits that enhance survival and reproduction, gradually changing the species over generations.

Front

What is the role of predators in Natural Selection?

Back

Predators influence Natural Selection by preying on the less adapted individuals, allowing the better adapted ones to survive.
