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

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed organisms for specific traits.

What are homologous structures?

Back

Homologous structures are body parts in different species that have similar structures but different functions, indicating a common ancestor.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that have similar functions but different structures, indicating no common ancestor.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the human appendix.

Front

What is stabilizing selection?

Back

Stabilizing selection is a type of natural selection that favors average individuals in a population.

Front

What is directional selection?

Back

Directional selection is a type of natural selection that favors one extreme phenotype over others.

Front

What is disruptive selection?

Back

Disruptive selection is a type of natural selection that favors extreme phenotypes over average ones.

Front

What is genetic drift?

Back

Genetic drift is a random change in allele frequencies in a population, which can lead to significant changes over time.
