8.2 & 9.1 Natural Selection & Evolution

When humans select which organisms are allowed to breed based on their traits

• natural selection

• artificial selection

• evolution

• adaptation

The only way new genes can be created is by

Organisms with the greatest fitness:

• live longest

• have the best qualities

• have the best offspring

• pass on their traits

Natural selection acts on

• individuals

• DNA

• populations

• forms new traits

A human's appendix is an example of a ____ structure

• vestigial

• analogous

• homologous

• imaginary

In order for a trait to become an adaptation it must be

A human arm, whale fin, and bird's wing are examples of

• analogous structures

• homologous structures

• vestigial structures

• artificial selection

Butterfly wings and bird wings are examples of

• analogous structures

• homologous structures

• vestigial structures

• adaptations

The movement of alleles into a new population is called

• migration

• founder effect

• gene flow

• bottleneck effect

• Finches live in different places, but eat the same food.
• Finches live in the same place, but eat different types of food.
• Finches live in different habitats and eat different types of food.
