The relevance of the pseudocoelom to phylogeny has been questioned. Rotifera and Nematoda both have a pseudocoelom. The molecular evidence suggests which of the following conclusions?

Molecular evidence has shown that rotifers are more closely related to the Lophotrochozoa, a group that includes mollusks and annelids, among others, than they are to nematodes. This suggests that the presence of a pseudocoelom in rotifers and nematodes is not indicative of a close evolutionary relationship, challenging the idea that this trait alone can determine phylogenetic relationships.
