Natural Selection

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 adaptation?

Back

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

Front

What is the role of competition in natural selection?

Back

Competition among individuals of a species for limited resources can lead to the survival of those best suited to their environment.

Front

How do mutations contribute to evolution?

Back

Mutations introduce genetic variation, which is essential for a population to evolve.

Front

What is genetic variation?

Back

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

Front

What does it mean for a species to evolve?

Back

Evolution refers to the change in the heritable characteristics of biological populations over successive generations.

Front

What is the significance of survival of the fittest?

Back

Survival of the fittest means that individuals with traits better suited to their environment are more likely to survive and reproduce.

Front

What is the difference between artificial selection and natural selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits, while natural selection occurs without human intervention.

Front

What is the Hardy-Weinberg equilibrium?

Back

The Hardy-Weinberg equilibrium is a principle that describes a population that is not evolving, where allele frequencies remain constant.

Front

What is the importance of genetic diversity?

Back

Genetic diversity is important because it increases a population's ability to adapt to changing environments.
