Placozoan evolutionary relationships to other animals are currently unclear, and different phylogenies can be created, depending on the character used to infer relatedness. Sponges have no tissues, but about 20 cell types. Tp (Trichoplax adhaerens) produces a neuropeptide almost identical to one found in cnidarians. The genome of Tp, though the smallest of any known animal, shares many features of complex eumetazoan (even human!) genomes. The next three questions refer to the phylogenetic trees that follow.

-Which phylogeny has been created by emphasizing a protein found in placozoans?

Quizplus · Accepted Answer

Phylogeny II is based on a protein found in placozoans, as placozoans are shown as the sister group to all other animals.
