Question

Quizplus · Accepted Answer

The DNA sequence is the best source of information for constructing an evolutionary classification of modern-day aquatic vertebrates. DNA provides information on the genetic relatedness between different species and can reveal the timing and order of evolutionary events. Organ structure, appendage position, and scale distribution can also provide useful information, but DNA sequencing provides the most comprehensive and accurate data for constructing evolutionary relationships.
