These clades have been examined several times with additional markers ... modern phylogenomic studies focused on the position of Placozoa within animals, i.e., Metazoa (Peterson and Eernisse, 2001; ...

Clades can be very large -- like the clade that includes all animals, called metazoa. Or tiny, like the haplorhine clade of monkeys, tarsiers, and apes. And we can have clades within clades within ...

We compared the gene content of the Xenoturbella genome to species across the Metazoa and its genome structure to several other high-quality draft animal genomes. We also used two remaining specimens ...
