Front

What is biogeography?

Back

Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time, offering insights into evolution.

Front

What is overproduction in natural selection?

Back

Overproduction refers to the phenomenon where organisms produce more offspring than can survive, leading to competition for resources.

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 the average or other extreme.

Front

What is disruptive selection?

Back

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