Total questions: 15
Worksheet time: 15mins
Whales are aquatic mammals that contain a pelvis bone. Even though it does not aid in its movement, the function must have been used by a common ancestor of the whale. Thus, the pelvis is referred to as a(n)
vestigial structure
analogous structure
homologous structure
The appendix, tailbone, and wisdom teeth are all examples of what type of structure in humans?
Homologous
Analogous
Vestigial
Modern
What type of structures are these?
homologous
vestigial
analogous
fossil
Structures with the same parts have different functions; suggests that organisms share a common ancestry
vestigial structures
homologous structures
adaptive radiation
fossil
Whales are aquatic mammals that contain a pelvis (hip) bone. Even though it does not aid in its movement, the function must have been used by a common ancestor of the whale. Thus, the pelvis is referred to as a(n)
vestigial structure
analogous structure
homologous structure
The similarities of bone structure in the diagram provide evidence of what?
The organisms probably use there forelimbs for the same thing.
The organisms evolved from a common ancestor.
The organisms have the same DNA.
All vertebrate species have identical forelimbs.
A human arm and a whale fin have similar bone structure but the whale fin is used for swimming and the arm is used for reaching and grabbing. What type of structures are these?
Homologous structures
Analogous structures
Vestigial structures
Fossil structures
Homologous Structure
Same function different structure
Comparative Embryology
Same structure different function
Biochemical Evidence
Comparing embryological development of different species
Analogous Structure
Comparing DNA and amino acid sequences of different species
Vestigial Structures
Structures in the body of an organism that no longer work.
Homologous structures are a result of
convergent evolution
divergent evolution
coevolution
artificial selection
Which of the following is an example of a vestigial structure in humans?
Appendix
Heart
Liver
Lungs
The wings of a bat and the arms of a human are considered what type of structures?
Homologous structures
Analogous structures
Vestigial structures
None of the above
What type of evolution leads to the development of homologous structures?
Convergent evolution
Divergent evolution
Parallel evolution
Artificial selection
Which of the following best describes vestigial structures?
Structures that have lost their original function
Structures that have the same function but different origins
Structures that are identical in different species
Structures that are newly evolved
The presence of pelvic bones in modern whales is an example of what type of structure?
Vestigial structure
Analogous structure
Homologous structure
Functional structure
Which of the following pairs are considered homologous structures?
Human arm and whale fin
Butterfly wing and bird wing
