Which groups of organisms show the closest relationship based upon skeletonbody symmetry and body segmentation?
Organisms with bilateral symmetry and segmented bodies, such as arthropods (insects, crustaceans) and annelids (segmented worms), show a close evolutionary relationship. Both groups exhibit a segmented body plan, which is a key feature that reflects their evolutionary lineage. Additionally, their bilateral symmetry allows for a more efficient body organization, which is advantageous for movement and interaction with their environment. This close relationship is further supported by molecular and genetic evidence.

What are annelids mollusks and arthropods classified as?
Annelids, mollusks, and arthropods are classified as invertebrates, which are animals lacking a backbone. They belong to the larger group called Coelomates, characterized by having a true coelom, a fluid-filled body cavity. Annelids are segmented worms, mollusks include diverse organisms like snails and octopuses, and arthropods encompass insects, arachnids, and crustaceans, all distinguished by their body structures and developmental processes.
Name 3 invertebrate groups?
3 of the water invertebrate groups are the annelids, arthropods and crustacean.
Which to species are more closely relatedworms and spiders or worms and ants?
Worms and ants are more closely related than worms and spiders. This is because worms (which are annelids) and ants (which are insects) are both part of the larger group of arthropods and share a more recent common ancestor. In contrast, spiders belong to a different phylum (arachnids) and have a more distant evolutionary relationship with worms.
What is closer related to humans mollusks or arthropods?
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.
Is a millipede is a worm?
No. Millipedes are myriapods, meaning "many feet". Centipedes are also myriapods. Segmented worms are annelids; earthworms and leaches belong to this group. Also, myriapods are arthropods; annelids are not.
Which type of animals are believed to have involved from segmented worms?
The arthropods (for instance, centipedes) are believed to have descended from the annelids (segmented worms).
What are the invertebrate groups?
The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
