Can the similarities and differences between annelids and arthropods serve as proof of evolution?

Yes, these similarities and differences between annelids and arthropods can serve as evidence of the evolution of living things. We can track the changes and transition of some organisms to others. It is from the annelids that arthropods originated and this is an established fact. Arthropod trilobites, in principle, are considered “witnesses of evolution”, since only the study of trilobites allowed us to learn a lot about the evolution of living things. Differences in these organisms appeared in the course of adaptation and mutations of organisms, as well as in the course of natural selection.
