Unfortunately, as an AI language model, I cannot create a Portfolio, but I can provide information and examples of animal phylogenetic trees.
A phylogenetic tree is a diagram showing the evolutionary relationships among different species. The study of phylogenetics aims to identify the evolutionary history of species and how they are related to each other.
Animal phylogenetic trees can vary depending on the source and the methods used to construct them. However, most animal phylogenetic trees include the following major groups:
1. Kingdom Animalia: This group includes all animals, from the simplest sponges to the most complex humans.
2. Phylum Porifera: Sponges are the only animals in this group, they are sessile and filter water through their bodies to obtain nutrients.
3. Phylum Cnidaria: Jellyfish, coral, and sea anemones belong to this group. They have stinging cells that they use to capture food.
4. Phylum Platyhelminthes: Flatworms are the only animals in this group. They are flat and have a simple body plan.
5. Phylum Nematoda: Roundworms are found in soil, water, and animals. Some species can be parasitic to humans and other animals.
6. Phylum Annelida: Segmented worms such as earthworms, leeches, and polychaetes belong to this group.
7. Phylum Arthropoda: Insects, spiders, crustaceans, and other arthropods all have a hard exoskeleton and jointed limbs.
8. Phylum Mollusca: Snails, clams, squid, and octopus all belong to this group. They have soft bodies and may have a shell.
9. Phylum Chordata: This group includes all vertebrates (animals with a backbone) and some invertebrates.
10. Subphylum Vertebrata: Fish, birds, reptiles, amphibians, and mammals all belong to this group. They are characterized by having a backbone which protects their spinal cord.
Examples of animal phylogenetic trees:
- A simple animal phylogenetic tree focused mainly on the major animal groups can be found on the Smithsonian National Museum of Natural History website: https://naturalhistory.si.edu/education/teaching-resources/life-science/animals-evolution
- A more complex and detailed animal phylogenetic tree can be found on the Tree of Life Web Project: https://tolweb.org/tree/
- The following image shows a simplified version of an animal phylogenetic tree including some of the major groupings:
Overall, animal phylogenetic trees provide a visual representation of the evolutionary relationships between different animal groups, helping us better understand the diversity of life on Earth.
