the canopy and grass lizards evolved from the twig lizard. The topics covered include adaptation, natural selection by predation, speciation, and reproductive barriers. So, we can start our tree by drawing the lamprey lineage branching off from the rest of the species, and we can place the appearance of jaws on the branch carrying the non-lamprey species. For instance, in our example (data repeated below for convenience), the lamprey, a jawless fish that lacks a true skeleton, is our outgroup. c. binomial nomenclature. We'd also have to choose which characteristics of those organisms to base our tree on (out of their many different physical, behavioral, and biochemical features). This playlist can be used to teach several core concepts of natural selection and speciation by connecting students to actual research on Caribbean anoles. a. Module 2: Phylogeny a. Analogous structures. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation. From the bar graph generated in the virtual lab (see below), how do the dewlap colors of the two Lizard Lab Flashcards | Quizlet My logic is C/D/F are the ancestral species. a) The more closely related lineages are the farther the distance between them on a cladogram. Iguana 2. that are similar according to body type are not more closely related based on the results What does this suggest about vertebrates? Starfish 5. Did you revise your criteria later? Wolf 4. c) Anolis olssoni is the oldest species in the tree Refer to the cladogram given below to answer the question. Show the remainder of the video (1:35end) after Part IV, question 11. By completing the resources in this playlist, students will be able to: This playlist can be used in AP/IB Biology and undergraduate college courses. 1. c) lizards with the same body type are not closely related, The anole lizard phylogenetic tree is more consistent with which of the following hypotheses: In the anole lizard tree, [Leiocephalus carinatus] is the outgroup and [Anolis cristalellus & A. pulchellus] are each others closest relatives. look. For example, anolis cybotes and anolis sagrei both are trunk ground anoles, but live on different islands. Insects & birds. Lizard Phylogeny.pdf - Short Film The Origin of Species: A "tree of life" explains: a. how organisms are related to each other b. how organisms differ from each other c. the lineages of various organisms d. all of the above, The structure of the forelimb of a bird is similar in structure to that of the forelimb of a mammal suggesting that they both descended from a common ancestor. The objectives of this lesson are to teach students how to: 1) Identify patterns in biological data, such as morphological characters (physical features), habitat, and geographical distribution. a. Lamprey. reaction, leading to similar characteristics. b. This interactive, modular lab explores the evolution of anole lizards in the Caribbean through data collection and analysis. What type of data did the researchers use for the phylogenetic analysis?
