Which of the following represents a conflict between phylogenetic trees estimated from morphological data versus DNA sequence data? a. choanoflagellates are the closest living relative of animals b. protostomes and dueterostomes are a fundamental split within the bilateria c.sponges are the most ancient, or basal, lineage of animals d. body cavities evolved in the following order : acoelomate, pseudocoelomate, coelomate
Homework Answers
The molecular data uses DNA, RNA and proteins for finding the evolutionary relationship whereas phylogenetic tree aim to find using evolutionary traits. The conflict between two method is the body cavity evolved in the order : aceolemate, pseusocolemate and coelomate. Hence, option d is correct .

3. According to the molecular sequence-based phylogenetic tree of animal life, which of the following is correct? a. Eucolomate animals evolved from pseudocoelomate animals, which in turn evolved from acoelomate animals. b. Segmentation probably evolved in only one clade, which includes more than one phylum showing segmentation. C. Segmentation evolved in some protostomes and some deuterostomes. d. Deuterostomes are more closely related to eucoelomate protostomes than to other protostomes that are pseudocoelomate or acoelomate. e. None of the above is...
