- Do these phylogenetic trees tell the same story?arrow_forwardDraw a simple phylogenetic tree for two sisters clades with a common ancestor. Each sister clade consists of two taxa. Define the following terms and use to label your diagram: clade, node, branch, common ancestor, and taxon.arrow_forwardWhat is a clade?arrow_forward
- What is the purpose of using an “outgroup” when reconstructing a phylogenetic tree? (Write 4 points)arrow_forwardWhen constructing phylogenetic trees, what is the purpose of applying maximum parsimony? Parsimony allows the researcher to "root" the tree. For trees based on morphology, the most parsimonious tree requires the maximum evolutionary events. The outgroup roots the tree, allowing the principle of parsimony to be applied. For trees based on morphology, the most parsimonious is the one that uses the simplest explanation of evolutionary events.arrow_forwardHow does phylogenetic tree relate to the passing of time?arrow_forward
- Which statement is usually true about phylogenetic trees? a) nodes represent points when traits have evolved b) branch tips that are next to each other are more closely related c) the branching pattern describes the hypothesized evolutionary relationships between the taxa d) the order of the branch tips (left to right) indicates which taxa are more advanced evolutionarilyarrow_forwardIn the last lab while creating a phylogenetic tree using PAUP/CIPRES, Fagus grandifolia was specified as the outgroup . Why is this step important? If the outgroup is not specified, PAUP or CIPRES will produce an unrooted tree in which outgroup is not connected to the rest of the tree by a common ancestor If the outgroup is not specified, PAUP or CIPRES will produce an unrooted tree in which the outgroup might not branch off prior to the common ancestor of the organisms under study O If the outgroup is not specified, PAUP or CIIPRES will produce an unrooted tree. Unrooted trees do not follow the Law of Parsimony All options are incorrectarrow_forwardWithin the field of phylogenetics, what does a “bootstrap value” represent?
