they are more related to roundworms
There is some debate about what other groups the nematodes, or roundworms, are most closely related to, and therefore from what group they descended. Nematodes are classified as being in the clade Ecdysozoa which also includes arthropods. If nematodes are truly closely related to arthropods then they share a common ancestor.
Gene based phylogenetic studies indicate that annelids and mollusks share a recent common ancestor
Roundworms (Nematoda) are related to arthropods because they both molt.Note; Crustaceans are arthropods. :P
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.
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.
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.
I have a sea star, a mollusc, and a mushroom. The sea star is most closely related to a human.
the answer is echinoderms are closer related to humans because they have a spine while mollusks do not
What is RNA closely related too? What is RNA closely related too?
