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

What is an adaptive trait?

Back

An adaptive trait is a characteristic that enhances an organism's ability to survive and reproduce in its environment.

Front

Who proposed the theory of evolution by natural selection?

Back

Charles Darwin proposed the theory of evolution by natural selection.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome, which can lead to new traits.

Front

What role do mutations play in evolution?

Back

Mutations introduce genetic variation, which can lead to new traits that may be beneficial for survival.

Front

What is the significance of a histogram in studying populations?

Back

A histogram visually represents the distribution of traits within a population, helping to identify variation.

Front

What does low variation in a population indicate?

Back

Low variation indicates that most individuals in the population have similar traits.

Front

What does high variation in a population suggest?

Back

High variation suggests that there is a wide range of traits present in the population.

Front

How can environmental factors influence traits in a population?

Back

Environmental factors can create pressures that favor certain traits, leading to changes in the population over time.

Front

What is the relationship between predators and prey in natural selection?

Back

Predators can influence the traits of prey populations by selecting for individuals with adaptive traits that enhance survival.
