Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.
Gene based phylogenetic studies indicate that annelids and mollusks share a recent common ancestor
Yes these two share common ancestors.
There has been no evidence of such an ancestor.
There is ample evidence of a common ancestor for all life on Earth, known as the Last Universal Common Ancestor (LUCA). This is supported by various lines of evidence, including genetic similarities, shared biochemical pathways, and the universal presence of certain biomolecules across diverse species.
No, mollusks have a true coelom instead of a pseudocoelom. The coelom is a part of mollusks and annelids that is a cavity within the mesoderm that is filled with fluid.
Scientists have identified Luca as the Last Universal Common Ancestor, or the common ancestor of all living organisms. Evidence for Luca comes from the study of genetic material and the similarities found in the genetic code of different species.
An Invertebrate is a creature with no back bone. The most common invertebrates include protozoa, annelids, echinoderms, mollusks and arthropods. Example of invertebrates: worms, snails, starfish, spiders and crabs.
Segmented worms
Many protista contain chloroplasts.
Physiological similarities suggest the species evolved from the same ancestor.
Because they are - they eat and move and breathe and are made of animal cells (nucleus, mitochondria, no chloroplasts). They evolved from the common ancestor of animals. They are animals in everything.
