Question
In the Metazoan phylogenetic tree to the right, circle the following clades: Lophotrochozoa – Label “A” Ecdysozoa – Label “B” Protostomia – Label “C”
The image is a phylogenetic tree that illustrates the evolutionary relationships among different animal phyla. The tree begins with a single branch that splits into several branches, each representing a major animal group. Here is a detailed breakdown of the tree structure: 1. **Porifera** - This branch represents the phylum Porifera, commonly known as sponges. 2. **Cnidaria** - This branch represents the phylum Cnidaria, which includes jellyfish, corals, and sea anemones. 3. Following the split, another branch divides into: - **Brachiopoda** - Representing the phylum Brachiopoda, marine animals with hard shells. - **Bryozoa** - Representing the phylum Bryozoa, which are small, colonial marine animals. 4. Another branch leads to: - **Mollusca** - Representing the phylum Mollusca, which includes snails, clams, and octopuses. 5. Further down the main branch, a new split shows: - **Arthropoda** - Representing the phylum Arthropoda, the largest animal phylum that includes insects, arachnids, and crustaceans. 6. The final split shows two branches: - **Echinodermata** - Representing the phylum Echinodermata, which includes sea stars and sea urchins. - **Chordata** - Representing the phylum Chordata, which includes all vertebrates such as fish, amphibians, reptiles, birds, and mammals. The phylogenetic tree visually represents the evolutionary pathways and relationships among these diverse groups, highlighting their shared ancestry and divergence over time.
