Explanation of Solution

Acoelomate, pseudocoelomate, and coelomate do not serve as reliable indicators of phylogenetic relationships even though these characters are ancestral because these characters re-evolved and appeared later again. Coelom evolved only one and is a common character in both protostomes and deuterostomes. However, certain protostomes and deuterostomes have evolved to form pseudocoelomic and acoelomic conditions. Further, the pseudocoelomic condition has exhibited convergent evolution in several animal clades and acoelomic condition re-evolved and appeared in Bilataria.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?
