ANS: A DIF: Easy REF: 5.0 OBJ: 5.0.a. Give an example of how the construction of phylogenetic trees and the ability to make inferences from such trees can be used as evidence in legal proceedings.

ANS: B DIF: Moderate REF: 5.1 OBJ: 5.1.a. Describe some of the methods used to construct phylogenetic trees and identify the logic of each approach as well as its strengths and weaknesses. MSC: Remembering3. The basic conceptual approach to phylogenetic tree building assumes that 4.
