Card 6 / 12:
Describe at least two major changes to the animal phylogenetic tree that have come about due to molecular or genetic findings.
Two new clades that comprise the two major groups of protostomes are called the lophotrochozoans and the ecdysozoans. The formation of these two clades came about through molecular research from DNA and protein data. Also, the novel phylum of worm called Acoelomorpha was determined due to molecular data that distinguished them from other flatworms.
