Currently, two of the extant porpoise species (Y and Z) are placed in the genus Tursiops, and a third species (X) is placed in the genus Delphinus. Assuming this classification reflects evolutionary relatedness, which of the following is the most accurate phylogenetic tree? d O C OB OA OD
Explain what a phylogeny tree and what the nodes on it represent and why it is useful to biologists.
Below 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? 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.
