Cnidarians (and ctenophores) are diploblastic animals. What is the fate of the ectodermal and endodermal cells in cnidarians? Answer this by keeping track of structures /Nssues /cells of “organs” that are derived from the ectoderm or from the endoderm or both and by which group/taxa. Is there a common pattern for all or are there variations?
This organism is an animal. What can you infer about its bodystructure and lifestyle (that might not be obvious from itsappearance)? This animal has a protostome developmentalpattern and a trochophore larva. Identify the major clades thatthis animal belongs to. Explain your selection, and describe whenthese clades originated and how they are related to one another.
A 2015 article in Nature has summarized the early history of jawed vertebrates using highlights from recent discoveries and how they have changed our understanding of vertebrate evolution. https://www.sciencedaily.com/releases/2014/04/140416133336.htm Question: Given these recent discoveries, how should the cladogram below change? Describe it. It will likely be helpful to reference a synapomorphy noted on the cladogram.
of this =rab or ditions ionary escen- se or 5. Describe two examples of vestigial structures that you can find among the Caminalcules. These are structures that have been reduced to the point that they are virtually useless. Ear muscles and the tail bones are examples of vestigial structures in our own species. Explain how vestigial structures provide clues about a species' evolutionary past. Illustrate your argument with vestigial structures found in humans or other real species.
When constructing this phylogenetic tree, several different options were possible. The tree with the least number of evolutionary changes is the one that was chosen as most probable.

Species Embryo (A-F) Describe the Anatomical Changes from Early to Late Stages Human Chicken Rabbit Tortoise Salamander В Fish A Guide Questions: 1. Look again at the six embryos in their earliest stages. Describe the patterns you see. What physical similarities exist between each of the embryos? 2. Does this suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common ancestor between each of these six organisms.
As we have discussed in class, phylogenies are hypotheses, and can therefore change over time with new evidence. Relatively recent and strong molecular evidence (that we did not discuss in class) suggests that all members of the Subphylum Hexapoda are derived from a common ancestor within the Subphylum Crustacea, as in the cladogram shown below. Given this new information, answer the question below. Note: Don't panic. Some of the names of these groups are new to you (Copepoda, Malacostraca, and Remipedia are all classes or subclasses within the Subphylum Crustacea), but this will not affect your ability to answer this question. Myriapoda Copepoda (Crustacea) Malacostraca (Crustacea) Hexapoda Remipedia (Crustacea) If we insisted that all groups must be categorized and named so that taxonomic ranks/names always include a single common ancestor and all of its descendants, how would this new evidence change our definition of a hexapod? Hexapoda and Melacostraca would have to be classified…

Based on this matrix, is my cladogram correctly done? 1.a) What species on the cladogram are endothermic (fully endothermic species only=those that maintain their body temperature only with their metabolism = not sharks for instance)? 1.b) Considering the location and relationship of endotherms on the cladogram, what type of character (homologous, homoplasy: convergence or reversal) do you think endothermy is? try to use specific terminology: character, homologous characters, nom homologous characters, character states (or evolutionary stages of a character), ancestral (plesiomorphic), derived (apomorphic), homoplasy, convergence, reversal....
Through the phylogenetic tree of major groups of vertebrates provided below, answer the given table by numbering and naming each node in the diagram. Then list the names of each group and write down the shared characteristic(s) of it. You may add more rows if needed.

describe one way in which limb development in Acanthostega could differ from that in modern tetrapods (e.g., mouse, human) to generate this digit pattern. Your description must include the name of at least one specific gene and at least one basic cellular mechanism.
