Answer
Look at the phylogenetic tree. Do robber crabs have more in common with humans or with sponges? What conclusion can you reach about their evolution?
explanation
Robber crabs have more in common with humans, which are vertebrates. Sponges are simple organisms that don’t have tissues. Crabs and humans have specialized cells and tissues, bilateral symmetry, and a coelom. According to the phylogenetic tree, vertebrates and arthropods have more nodes, or common ancestors, than crabs have with sponges.
