Question

Quizplus · Accepted Answer

Phylogenetic systems of classification attempt to reflect evolutionary relationships among species based on shared ancestry and common descent. This is usually done using molecular data such as DNA or RNA sequences, and by analyzing similarities and differences between organisms at the genetic level. While morphological, structural, and biochemical characteristics can provide some clues as to evolutionary relationships, they are not always reliable indicators on their own.
