Answer:
Option C, cladistics reveals relative evolutionary branching by utilizing genetic analysis
Explanation:
Cladistics classification is a way of classifying organisms biologically in a way that a relationship between their shared traits could be established which leads to identification of closely related organism and species. It further helps to identify ancestry history of closely related species to identify closely related common ancestors and the evolution of various characteristics.
Basically in Cladistics study, species are arranged on a phylogenetic tree based on the time of their emergence from any other group.
Hence, option C is correct.
