Multiple Choice
Which molecular evidence supports the theory of evolution in organic chemistry?
A
The similarity of DNA sequences among diverse organisms
B
The fossil record showing gradual changes over time
C
The occurrence of analogous structures in unrelated species
D
The presence of homologous structures in different species
Verified step by step guidance
1
Understand that the theory of evolution is supported by various types of evidence, including molecular evidence.
Recognize that DNA sequences provide molecular evidence for evolution. Similar DNA sequences among diverse organisms suggest a common ancestry.
Consider the fossil record as another form of evidence, showing gradual changes in species over time, which supports evolutionary theory.
Differentiate between analogous and homologous structures. Analogous structures arise from convergent evolution, where unrelated species develop similar traits independently. Homologous structures, however, indicate a common ancestry and are found in different species.
Connect these concepts to the theory of evolution: Similar DNA sequences and homologous structures support the idea of common ancestry, while the fossil record provides a historical context for evolutionary changes.
