Gene based phylogenetic studies indicate that annelids and mollusks share a recent common ancestor
No, leeches are not mollusks; they belong to the phylum Annelida, which includes segmented worms. Mollusks, such as snails and clams, are part of a different phylum called Mollusca. Leeches are more closely related to earthworms and other annelids than to mollusks.
The kinds of evidence that indicates how closely species are related are evidence of DNA and protein structure.
they are more related to roundworms
As like all other ocean creatures, they have gills. U have to look closely.
Annelida is the phylum Annelids belong to, hope I helped :)
Both Clams and Octopuses are Mollusks. Clams are under the subphylum Bivalves, and octopuses are cephalopods. Lobsters on the other hand, are not Mollusks. They are crustaceans. Also, an obvious difference is the lobsters exoskeleton.
contraction of cytoplasm XD I love Navdeep <3
Arthropods are more closely related to humans than mollusks. Both humans and arthropods belong to the larger group called Ecdysozoa, which is characterized by molting exoskeletons, while mollusks belong to a separate group called Lophotrochozoa. This evolutionary relationship places arthropods and humans closer on the tree of life.
Birds

They are not THAT closely related; bats are mammals, not birds. Both mammals and birds are vertebrate animals.
the role in which molecular evidence play in determining how closely two species are related to each other is through the cladogram
