Evidence from body structure and development MCQs with solutions
10 of the 13 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.
Structures with common evolutionary origin but possibly different functions:
- A. homologous structures
- B. vestigial structures only
- C. analogous structures
- D. acquired characters
Structures with similar function but different evolutionary origin:
- A. vestigial organs
- B. analogous structures
- C. fossils
- D. homologous structures
Homologous organs provide evidence for evolution because they
- A. share a basic structural origin despite differing functions
- B. always perform identical functions
- C. occur only in unrelated organisms
- D. have no developmental similarity
Analogous organs are structures that
- A. perform similar functions but have different evolutionary origins
- B. share the same basic origin but different functions
- C. are always vestigial
- D. occur only in embryos
Vestigial structures are useful evolutionary evidence because they are
- A. reduced remnants of structures that were more functional in ancestors
- B. new organs with no ancestral history
- C. always essential for survival
- D. identical in all species
The forelimbs of humans, whales, bats and horses have the same basic skeletal plan but different functions. They are
- A. homologous structures
- B. analogous structures
- C. vestigial structures only
- D. unrelated structures
The wings of birds and insects both enable flight but arose from very different structural origins. As wings, they are
- A. analogous
- B. homologous
- C. vestigial
- D. identical by descent
The human appendix is often cited in evolutionary discussions as a
- A. vestigial structure
- B. homologous wing
- C. newly evolved organ with no ancestry
- D. molecular clock
Similar early embryonic features among vertebrates are often interpreted as evidence of
- A. shared evolutionary ancestry
- B. complete absence of evolution
- C. identical adult forms
- D. unrelated developmental programs
Which pair is the best example of homologous structures?
- A. Human arm and whale flipper
- B. Bird wing and butterfly wing as flight organs
- C. Fish fin and insect wing
- D. Butterfly wing and bat wing as flight surfaces
Common mistakes in Evidence from body structure and development
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Associates convergence with common structural ancestry.
- Confuses divergent and convergent evolution.
- Uses function alone to classify evolutionary similarity.
