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 genomic features of placozoans?
A) I
B) II
C) III

Quizplus · Accepted Answer

Phylogeny III has been created by emphasizing genomic features of placozoans, as genomic features include DNA sequences, gene content, and other molecular data that provide a detailed basis for constructing phylogenetic trees, offering insights into the evolutionary relationships and history of placozoans.
