B bilateral symmetry
C limited to sexual reproduction
D a homeobox-containing family of genes called Hox genes

B Evolution of the Hox gene complex provided developmental flexibility.
C A rise in atmospheric oxygen led to success of large animals with high metabolic rates.

other three groups listed here is the

it is necessary for a complete digestive tract.
it permits the development of an open circulatory system.

D have a body cavity partially lined with tissue derived from mesoderm ... have a body cavity completely
lined with tissue derived from mesoderm
____ 14 Which of the following is NOT a difference between protostomes and deuterostomes?
A the fate of the blastopore
B the presence of a body cavity
C the cleavage plane of the embryo
D the timing of the determination of embryonic cells
____ 15 Pictured here are two phylogenetic hypotheses regarding the relationships of the animal phyla. The tree that is
based on molecular evidence (right) differs from the tree based on morphological evidence (left) in that it
A depicts sponges as basal animals.
B divides protostomes into two taxa.
C depicts cnidarians as basal eumetazoans.
D suggests that the animal clade is polyphyletic.
