Is there no evidence of a common 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.


Do mollusks have a pseudocoelom?

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.


What is our evidence of Luca, the common ancestor that we can link all living organisms to?

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.
