Question

Quizplus · Accepted Answer

A phylogenetic tree shows the evolutionary relationships and common ancestors among different species or groups of organisms. Therefore, it indicates common ancestors. B, C, D, and E are incorrect because a phylogenetic tree does not necessarily show the taxonomic classification, use only derived characters, indicate common ancestors for each family, or include the organism's order and class.
