- 12. Multiple Choice
What is a vestigial structure?
A structure that has origins in a common ancestor, but has evolved to perform the same functions
A structure that has origins in a common ancestor, but has evolved to perform different functions
A structure that makes an organism better suited to a habitat
A structure that has lost its function but is still part of the organism
- 13. Multiple Choice
Which of the following is evidence of a common ancestor?
Vestigial structures
Fossil record
Similarities in the embryo
All of these
- 14. Multiple Choice
The structures of the front flipper of a whale and the forearm of a wolf have similar bone structure and derive from a common ancestor. This is an example of __________.
analogous structures
homologous structures
vestigial structures
None of these
- 15. Multiple Choice
How did Darwin's finches help support his theory of evolution?
The finches all lived on different islands
Only the largest birds had survived on the island, while the smaller ones went extinct
The birds were different colors, which allowed for camouflage in different habitats
The size and shape of their beaks varied due to the different environments they lived
- 16. Multiple Choice
Structures that were once functional in the past but no longer serve a purpose due to evolutionary adaptations and physiological changes are referred to as __________ structures.
homologous structures
analogous structures
vestigial structures
None of these
- 17. Multiple Choice
Which of the following is one of Charles Darwin’s theories about evolution and natural selection?
The environment in which a species lives is unrelated to natural selection
New species that appear in the fossil record are actually descendants of older species
Natural selection is caused by human intervention
Changes to an organism occur rapidly
- 18. Multiple Choice
How do fossils support evolution?
The fossil record provides evidence that organisms have changed over time.
Individual species disappear and reappear in the fossil record over time.
The fossil record provides evidence that all organisms developed at the same time.
Organisms in the fossil record are identical to living organisms.
