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

What is variation in a population?

Back

Variation refers to the differences in traits among individuals in a population.

How does water clarity affect guppy coloration?

Back

As water clarity decreases, darker coloration in guppies becomes more prevalent as it provides better camouflage.

Front

What is the significance of trait prevalence in a population?

Back

Trait prevalence indicates which traits are favored by natural selection and are more common in a population over time.

Front

What happens to a population when it is isolated from its natural habitat?

Back

Isolated populations may experience changes in traits due to different selective pressures, leading to evolution.

Front

What is the role of competition in natural selection?

Back

Competition for resources can lead to natural selection, as individuals with advantageous traits are more likely to survive and reproduce.

Front

What is the difference between adaptive and non-adaptive traits?

Back

Adaptive traits improve survival and reproduction, while non-adaptive traits do not provide any advantage.

Front

How can environmental changes impact a species?

Back

Environmental changes can alter selective pressures, leading to changes in trait prevalence and potentially causing evolution.

Front

What is the concept of fitness in natural selection?

Back

Fitness refers to an organism's ability to survive, reproduce, and pass on its genes to the next generation.
