- How does a phylogenetic tree indicate major evolutionary events within a lineage?arrow_forwardWhich 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_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_forward
