E) based solely on rRNA sequence.

Question

Quizplus · Accepted Answer

A consensus tree that accurately summarizes evolutionary relationships among organisms is typically constructed using data from multiple gene sequences. This approach, known as molecular phylogenetics, provides a more comprehensive view of evolutionary history than using morphological characteristics alone, as it reflects the genetic similarities and differences between organisms. While lateral gene transfer may occur in certain organisms, it is not typically reflected in a consensus tree summarizing overall evolutionary relationships. A single DNA sequence may not accurately reflect the complexity of evolutionary history, and relying solely on rRNA sequence could overlook other important genetic data.
