Natural Selection Review

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 characteristic or trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What is the role of mutation in evolution?

Back

Mutation introduces new genetic variations in a population, which can lead to new traits that may be beneficial for survival.

Front

Who proposed the theory of natural selection?

Back

Charles Darwin proposed the theory of natural selection.

Front

What is the significance of genetic variation?

Back

Genetic variation is crucial for a population's ability to adapt to changing environments and is the raw material for evolution.

Front

How does the environment influence natural selection?

Back

The environment determines which traits are advantageous, thus influencing which organisms survive and reproduce.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype is the observable physical or behavioral traits.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

What is the concept of survival of the fittest?

Back

Survival of the fittest refers to the idea that individuals best suited to their environment are more likely to survive and reproduce.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species due to evolutionary changes.
