- Understanding phylogenetic trees Rodents & rabbits Crocodiles Sharks Ray-finned fish Primates Dinosaurs & birds Hair Two post-orbital fenestrae +Amniotic egg Four limbs BONY SKELETON Vertebrae 6) Which characteristic(s) differ between Sharks and this taxon?| Hypothesis 1 In the phylogenetic tree above Sharks are most closely related to which other taxa? AmphibiansHair. Kangaroo, Cat Bones: Dolphin Limbs: Lizard Jaws Shark Segmented Earth worm Multicellular Sponge 7. Create a cladogram based on the morphological and molecular evidence.fossil bird salamander 2. This fossil bird and this living salamander both have tails. However, they have different tail structures. The bird has a very short tail made of just one bone that helps it have a light skeleton for flying. The salamander has a long tail with many bones that helps it balance while it runs. What most likely explains why both the bird and salamander have tails and why the tails are different? a) The salamander and bird both inherited tails from a shared ancestor population, but this population separated into different environments. In each environment, different types of tails evolved, which helped the populations survive. It is impossible to explain the body structures of different species. The way that structures change over time is very complex, and no one has ever observed these changes occurring. The bird and salamander are different species, so they do not share an ancestor population. These species had separate ancestor populations, and each evolved a…
- Animal Kingdom, Part I Background: There are ten major phyla that represent the invertebrate animals. Though they all share animal characteristics, each phylum has unique characteristics that allow for identification and classification of those organisms. Scientists do not always rely solely on their memory to help them classify animals, they often rely on reference materials. In this activity, you will create your own reference for the animal kingdom. Instructions: Review the information found in the lessons on invertebrates including The Animal Kingdom, Body Plans, Phylum Placazoa, Phylum Porifera to review the key characteristics that define the phyla that you study. Create a concept map or illustrated drawing for each phylum (Placazoa and Porifera) that will help you classify invertebrate animals into that group.Question: Craniata includes animals within Chordata that have a skull. True or False?PHYLOGENETIC ANALYSIS: Refer to the Pratachardaten phylogenetic tree. Write your answers for the following, phrase sentence form. 1. Are deuterostomes in or in related to protostome (Yes or No)? Explain briefly 2. What Syorlesiamecebic character Protostomes Deuterostomes is the CHORDATES Tripartite coelom, larva Chordate ancestor (Notochord, post-anal tail, dorsal hollow nerve cord) of deuterostomes? 3. What is the Deuterostome ancestor (Gill slits) of echinoderms and character Bilateral ancestor (Dorsoventral axis, mesoderm, through gut, cephalization, hox domains in trunk, tinman heart, pax6/emw/otx domains in head) hemichordates? 4. Is the group of chordates considered monophyletic (Yes or No)? Explain briefly. eozoskpog- FLophotrochozoa Echinoderms Hemichordates Urochordates Cephalochordates Vertebrates
