- On the right 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 tooth, thus likely a carnivore. Which of the following statements is correct? O The most recent common ancestor for species A to H is probably a carnivore: O The most recent common ancestor for species A to H is probably a herbivore OIt is impossible to tell what the main food source is for the most recent common ancestor of species A to H. O 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.

OOO Branch length Operational Taxonomic Units (OTUS) Branch node Bootstrap valuearrow_forwardIt is known that it takes very long periods of time for new species to develop, and yet the fossil record for many organisms is characterized by long periods of Stasis (no change) followed by short bursts of intense Speciation (the disappearance of one species followed by the appearance of a new species). Thus in the fossil record, organisms seem to stay the same for long periods of time followed by a “sudden” change in the organisms (sudden with respect to evolution and geology). In other words, it appears that new species evolve suddenly as opposed to over long periods of time. The Theory of Punctuated Equilibrium helps to explain these seemingly contradictory occurrences in the fossil record. Discuss how Punctuated Equilibrium works (think about small offshoot populations that break off from the main population) and how it can explain the fossil record evidence. (Be sure to include information about why fossils of the offshoot population would be rare.)arrow_forward

Evolutionary history, or phylogeny, is represented visually by a phylogenetic tree. Trees have a common structure, with a root, nodes, and branches.

- Below is an example of a particular kind of phylogenetic tree called a chronogram. Chronoograms are named because the length of the branches represents different lengths of time. Nodes are represented by vertical lines, and branches with horizontal ones. They can be arranged horizontally, with the most recent evolutions on the right. Given this information, the taxa that is most closely related to Dubautia ciliolata c. 529 (highlighted below) is _________________ (make sure to type exactly the same characters, including the numbers; do not italicize).arrow_forwardDraw a phylogenythat accurately portrays the evolutionary relationships among the organisms listed. Each organism listed should be at the tip of a branch on the tree. Use the internet to discover what type of organisms they are, and refer to the textbook and course notes as you determine the relationships among these organisms. Label the phylogeny with each of the 6 species listed and write on the tree where the following derived traits evolved: specialized tissues, radial symmetry, bilateral symmetry, deuterostomy, protostomy, and ecdysozoan cuticle (the need for an animal to molt in order to grow).
