Question

multiple choice question
in molecular evolution studies, dna sequence similarities present in a group of species usually represent
fossilization type.
convergent evolution.
analogy.
homology.

Explanation:

• Fossilization type relates to how organisms become fossils, not DNA sequence similarities.
• Convergent evolution leads to analogous structures (similar functions, different origins), not DNA similarity from common ancestry.
• Analogy refers to similar traits due to convergent evolution, not DNA sequence ties.
• Homology refers to traits (including DNA sequences) inherited from a common ancestor, so DNA similarities in a species group represent homology.

Answer:

D. homology.
