Page 1 Name _________________________ Integrative Biology 200B Spring 2001 "PRINCIPLES OF PHYLOGENETICS: ECOLOGY AND EVOLUTION" Quiz 1 1. (15 points) Some workers have argued that vicarience biogeography is nothing more than dispersal at larger temporal and spatial scales. Do you agree or disagree and why? 2. (15 points) You have three data sets - molecular, behavioral, and morphological – and you want to determine the amount of phylogenetic information present in each one. What analyses would you undertake to determine this? 3. (15 points) What is or should be the relationship between phylogenetics and conservation?Page 2 Name _________________________ 4. (25 points) Briefly contrast the following pairs of terms (Use diagrams if they help): Strict consensus trees vs. majority-rule consensus trees transformational vs. taxic homology additive binary recoding vs. non-additive binary recoding replicator vs. interactor neoteny vs. progenesisPage 3 Name _________________________ 5. (30 points) What sort of comparative method or approach would you apply to the following evolutionary questions (e.g., what assumptions would you make, what kind of data would you require, how would you generate a null hypothesis, how would you judge statistical significance?): a. (5 pts.) Has a particular clade of parasitic plants closely co-evolved with its clade of host plants? b. (5 pts.) Two lineages have merged, producing a new lineage (e.g., "speciation through allopolyploidy") c. (5 pts.) Is molecular evolutionary change concentrated in speciation events? d. (5 pts.) Are flavonoids an adaptation to prevent UV damage in land plants?Page 4 Name _________________________ e. (5 pts.) There is trend towards increasing body size within lineages of mammals (Cope's Rule). f. (5 pts.) Are fleshy-fruited plants more likely to evolve a dioecious condition (i.e., separate sexes on different
