Natural Selection

Front

What is natural selection?

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring.

Front

How does evolution occur?

Back

Evolution occurs through small changes that are passed down through many generations.

Front

True or False: Individuals undergo evolution.

Back

False. Evolution occurs at the population level, not at the individual level.

Front

What trait is most likely inherited?

Back

Traits such as height are inherited, while skills like swimming or playing drums are learned.

Front

Which organisms are most likely to survive in a changing environment?

Back

The best adapted organisms are most likely to survive.

Front

What happens to moths when their environment changes color?

Back

Moths that are better camouflaged to their environment (e.g., dark moths on soot-covered trees) are more likely to survive.

Front

What is adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

Define genetic variation.

Back

Genetic variation refers to the differences in DNA among individuals within a population.

Front

What role does competition play in natural selection?

Back

Competition for resources leads to survival of the fittest, where only the best adapted individuals survive.

Front

What is the significance of overproduction in natural selection?

Back

Overproduction leads to competition, which drives natural selection as not all offspring will survive.
