Types of Evolution

Coevolution is the

• Species looking similar due to a common ancestor

• Species looking similar due to a common environment

• evolution of two species that do not interact

• evolution of one species in response to evolution in another species

Which traits were selected for in whale ancestors?

• Traits that helped them walk on land

• Traits that helped them move in water

• Traits that helped them give birth

What is the definition of Convergent Evolution?

• The process where groups from the same common ancestor evolve and accumulate differences, resulting in the formation of new species.

• The process where species that are not closely related independently evolve functionally or visually similar structures.

• The process by which development of species is marked by isolated episodes of rapid adaptation to environments between long periods of little or no change.

• The process of development of  evolutionary change that occurs between pairs of species as they interact with one another.

What is a Homologous Structure?

• Features of different species that are similar in function but not in structure

• Similar features in organisms that share a common ancestor, but the features serve completely different functions

• Feature that a species inherited from an ancestor but is no longer used

Which of the following best describes adaptive radiation?

• A) The process by which unrelated species become more similar due to similar environments.

• B) The rapid evolution of diversely adapted species from a common ancestor.

• C) The gradual change in species over long periods of time.

• D) The extinction of species due to environmental changes.
