Understanding Evolution and Natural Selection

Front

What is adaptation in the context of evolution?

Back

Adaptation refers to the process by which a species becomes better suited to its environment through changes in traits that enhance survival and reproduction.

Front

What are the three main types of adaptations?

Back

The three main types of adaptations are behavioral, structural, and functional adaptations.

Front

What is natural selection?

Back

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

Front

Who is known for the theory of evolution by natural selection?

Back

Charles Darwin is most closely associated with the theory of evolution by natural selection.

Front

What is a structural adaptation?

Back

A structural adaptation is a physical feature of an organism that enhances its survival, such as the white fur of rabbits in snowy environments.

Front

What is a behavioral adaptation?

Back

A behavioral adaptation is an action or behavior that helps an organism survive, such as migration in response to seasonal changes.

Front

What is functional adaptation?

Back

Functional adaptation refers to internal body processes that enhance survival, such as the ability of some animals to regulate their body temperature.

Front

How does camouflage serve as an adaptation?

Back

Camouflage helps organisms blend into their environment, making them less visible to predators and increasing their chances of survival.

Front

What evidence supports the theory of natural selection?

Back

Evidence for natural selection includes observations of changes in species over time, such as the adaptation of lizards to darker environments.

Front

What role does genetic variation play in evolution?

Back

Genetic variation provides the raw material for natural selection, allowing some individuals to have traits that enhance survival and reproduction.
