history of a species. The evolutionary pathway has a tree-like structure. Draw a large V, the base of the V represents your first node and is the common ancestor that split into 2 lineages. Introduction: Cladistics is an approach that distinguishes between the similarities due to ancestral reasons from the similarities due to derived characters. Based on the cladogram shown, we can conclude that species 2 is most closely related to species A. Don't forget to Include the root. Subsequently, the larger group, or clade, will contain increasingly smaller groups (clades) that share the traits of the clades before them, but also exhibit distinct changes as the organism evolves. (4) Using the hypothetical organisms and the information provided in tables 1 and 2, construct the best cladogram to explain the distribution of characters across the taxa. For example for Table 1, it is the lamprey. Taxonomic congruence is the degree to which classifications of the same organisms contain the same groupings. evolutionary history. a) placing organism in groups of related species and lists of characteristics of known organisms is classification. Both morphological data and molecular data can be used to organize each group.

USING complete sentences, explain why you put each organism where you did on the cladogram. Plants and animals consist of different types of cell that work together. Mark an “X” if an organism has the trait. Cladistics is a way of sorting organisms based on characteristics that were derived from a common ancestor. Selection can act at multiple levels simultaneously. The exception to this could be the organism in the outgroup, as the outgroup is meant to be used as a point of comparison against the other organisms.
