Front

What is Evolution?

Back

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

Back

An inherited trait is a characteristic that is passed from parents to offspring through genes.

Front

What is an Acquired Trait?

Back

An acquired trait is a characteristic that an organism develops during its lifetime, not passed on genetically.

Front

What is Directional Selection?

Back

Directional Selection is a type of natural selection that favors one extreme phenotype over the mean or other extreme.

Front

What is Stabilizing Selection?

Back

Stabilizing Selection is a type of natural selection that favors average phenotypes and reduces variation.

Front

What is Disruptive Selection?

Back

Disruptive Selection is a type of natural selection that favors extreme phenotypes over intermediate phenotypes.

Front

What is Adaptation?

Back

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

Front

What is a Common Ancestor?

Back

A common ancestor is an ancestral species from which multiple species have evolved.
