Question

can someone help me?

solve this phylogenetic treePhylogenetic tree showing the hypothesized relationships for nine animal phyla. an Inferred from morphological and developmental characters (based on Freeman 2005, 10); b inferred from molecular characters. In a closed book laboratory exercise, students are asked to map each of three characters onto each of these two trees. The characters are (1) body cavity (acoelomate, pseudocoelomate, or eucoelomate), (2) number of opening to the digestive tract (one or two), and (3) segmented body (yes or no). As part of a lecture exam, students are asked to map each of four characters onto tree (a). The characters are: (1) body cavity (acoelomate, pseudocoelomate, or eucoelomate; the question, (2) embryological development (protostome or deuterostome), (3) true tissues, and (4) symmetry (radial or bilateral)please

Answer 1

Please look in the image for solution:

P depicts pseudocoelomates

E depicts eucoelomates

Pr depicts protosome

D depicts deuterostome

R depicts radial symmetry

B depicts bilateral symmetry

C depicts cellular

T tissue

O depicts organ

Os depicts organ system

Circle one is most parsimonious because of least character transistion.
