The classification which is consistent with the goal of including only monophyletic groups. Given: Classification one: Named group Amphibian Mammalia Reptilian Aves Included taxa Frogs, salamanders, and caecilians Mammals Lizards, turtles, and crocodiles Birds Classification two: Named group Amphibia Mammalia Reptilian Included taxa Frogs, salamanders, and caecilians Mammals Lizards, turtles, crocodiles, and birds Classification three: Named group Amphibian Homothermia Reptilia Included taxa Frogs, salamanders, and caecilians Mammals and birds Lizards, turtles, and crocodiles Introduction: There are three types of classification category. They are monophyletic, polyphyletic, and paraphyletic. Monophyletic is the group which has an ancestor and all the descendants are of the ancestor. Polyphyletic is the group which does not include any common ancestors in the group of organisms. Paraphyletic is the group which includes ancestors but some of the descendants are of the ancestors.

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. Node Number (e.g. 1 - Gnasthostomata) Animal Group 1 Animal Group 2 Shared Characteristics of Animal Group 1 & 2

Define the following terms in your own words: Taxonomy Classification Description Hierarchy Identification Nomenclature Systematics Phylogeny Character Analogous character Homologous character Character state Clade Cladogram

Using the terms listed below, answer all the parts to this question regarding the cladogram for the frogs Anatomy of a Cladogram Sympleisiomorphies—shared ancestral states Synapomorphies—shared, derived character states Autapomorphies—unique, derived character states Homoplasies—the result of parallel or convergent evolution where 2 or more organisms independently acquire the same character state (could be the result of a reversal—when, in a particular lineage, a character reverts from a derived back to an ancestral state). Similarity in appearance, but not origin. Monophyletic group—group of all descendants of a common ancestor Paraphyletic group—group of some, but not all, descendants of a common ancestor Polyphyletic group – group of individuals that descend from more than one common ancestor Polytomy—3 or more taxa emerging from a single node who do not share the most common ancestor Homologies—Similarities resulting from descent from a common ancestor Analogies - Similarities…
