Evolutionary Science Review

Your appendix is an example of a(n)

• vestigial structure

• analogous structure

• homologous structure

The leg of a cat and the leg of a dog are examples of:

• vestigial structures

• analogous structures

• homologous structures

Bat wings and bird wings are examples of:

• vestigial structures

• analogous structures

• homologous structures

Structures that are similar in function but DIFFERENT in structure are:

• vestigial structures

• analogous structures

• homologous structures

Structures that are similar in structure AND in function are:

• vestigial structures

• analogous structures

• homologous structures

Genetic traits that are beneficial and aid in survival are:

• adaptations

• vestigial

• kinesthetic

• reproductive success

When humans choose which two organisms breed, it is known as:

• artificial selection

• natural selection

• physical selection

• uneven selection

In order for two groups of organisms to become different enough to be different species:

• They cannot continue to breed together

• They must have different courtship dances.

• They must have a mountain between them.

• None of the above.

• Directional

• Disruptive
