Whаt is the difference between shаred аncestral and shared derived characters?
Systemаtics is the study оf biоlоgicаl diversity аnd the evolutionary relationships among organisms. Scientists use phylogenetic trees to illustrate these relationships, often grouping organisms into clades. A clade is a monophyletic group, meaning it consists of an ancestral species and all of its descendants. This method helps distinguish between shared ancestral characters (traits originating in an ancestor) and shared derived characters (evolutionary novelties unique to a particular clade). A group of biologists studied five modern species (V, W, X, Y, and Z) to determine their evolutionary history based on shared derived characters. The resulting phylogenetic tree is shown in Figure 1. act quest.png Based on Figure 1 and the provided text, which of the following groups of species would be considered a monophyletic group (clade)?
