- Compare the two theories of evolution, gradualism and punctuated equilibrium.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_forwardBelow is a phylogeny depicting the relationship among eight animal species (A to H). Next to the species names are the tooth morphology of each species. For example, species A has prominent molar teeth, thus likely a herbivore. On the other hand, species C has prominent canine teeth, thus likely a carnivore. Which of the following statements is correct? A C D E H. The most recent common ancestor for species A to H is probably a carnivore. The most recent common ancestor for species A to H is probably a herbivore. It is impossible to tell what the main food source is for the most recent common ancestor of species A to H. For species C, D, E, F, G, there are four evolutionary events that lead to the evolution of canine tooth morphology. IF the common ancestor of species C, D, E, F, G is a carnivore, then the molar teeth for species D is a plesiomorphy.arrow_forward

- In the figure, the letters A-G represent individual species that all descended from a common ancestor. DEFG Which of the following conclusions regarding the phylogeny of these organisms can be made from this tree? B is more closely related to G than it is to A. A is more closely related to D than it is to C. G is more closely related to A than it is to F. D is more closely related to E than it is to C.arrow_forwardGiven the phylogenetic tree shown below, which of the following two species (A-F) most recently shared a common ancestor?
