- Phylogeny refers to the evolutionary descent of taxa. It refers to the relationship between ancestors and descendants and relationships among descendant taxa. It shows the lineage of taxa which can be summarized in a branching diagram called a phylogenetic tree.1. Express some basic evolutionary relationships among groups of microorganisms, plants, and animals; 2. Illustrate the relationship of organisms with their environment; and 3. Analyze environmental factors contributing to biodiversity richness and lossarrow_forwardAll of the following are true about phylogenies, EXCEPT: a. They are considered an unbiased reconstruction of evolutionary relationships. b. We use them to predict the emergence of traits in the fossil record. c. They are, at best, a hypothesis about the relationships among extant species. d. We use the rule of parsimony to reconstruct evolutionary history.arrow_forwardWhich of the following is TRUE about a phylogenetic tree? It provides a drawing the reflects the proven relationships between living and extinct species. b It provides a hypothetical model of the relationships between extinct species. c It provides a hypothetical model of the relationships between living and extinct species. d It a diagram used by scientists that provides a model of evolutionary relationships without the need for scientific data.arrow_forward
- In a phylogenetic tree, Species 1 and 2 are distantly related to one another but are both darkly pigmented. Species 3 which is unpigmented is a sister taxon to Species 2. The common ancestor to all three species is darkly pigmented; thus, this trait in the phylogeny is considered to be a - A. homoplasy. B. synapomorphy. C. apomorphy. D. symplesiomorphy.arrow_forwardA taxonomic group that contains species that have similar phenotypes due to convergent evolution is a. paraphyletic. b. monophyletic. c. polyphyletic. d. a good cladistic group.arrow_forwardYou are photojournalist in a science magazine. For its next issue, you have been assigned to feature the difference between 3- Domain Scheme from 5-Kingdom Scheme of classification of living things. Using your knowledge and concept of taxonomy. a. the 3-domain scheme, description of each and sample organisms;b. the 5-kingdom scheme, description of each and sample organisms; andc. includes the technologies used as basis in the shifting of the classification from the kingdom scheme to domain scheme.arrow_forward
- Monophyletic groups are desirable in classification as they Select one: a.reflect evolutionary relationships b. minimise name changes from old to new classifications c. result in fewer groups and are therefore more parsimoniousarrow_forwardDerived characters are traits: A. that are more complicated than ancestral characters B. that characterize the last common ancestor of a particular collection of species. C. that have evolved after the last common ancestor of a particulan collection of species. D. that are less well suited to the environment than ancestral characters.arrow_forwardA scientist has developed 3 different phylogenies that describe the relationships between different species of elephants. In Phylogeny A, there are 4 total changes that resulted in 4 different species. In Phylogenies B and C, there are still 4 total species represented, however, they take 6 and 8 changes, respectively, to create them. Which phylogeny is probably correct? a.)Phylogeny A b.)Phylogeny B c.)Phylogeny C d.)All of the above, given every clade contains the same organismsarrow_forward
- Which of the following most likely demonstrates that classification is the basis of evolutionary relatedness? A. Organisms that share similar characteristics are impliedly understood to have common ancestors, thus having an evolutionary relationship. B. Classification is to organize organisms into groups based on their differences and similarities and evolutionary history, so as evolution changes, classification will also change C. Classification based on evolutionary relatedness always infer that all organisms that evolved similarly shares the same history. D. Homologous structures among organisms depicts the same evolutionary history or paths.arrow_forwardA paraphyletic group includes a. an ancestor and all of its descendants. b. an ancestor and some of its descendants. c. descendants of more than one common ancestor. d. All of the choices are correct.arrow_forwardWhich of the following is/are TRUE in phylogenetic analysis? 0000000 A. In a phylogram, the longer the branch length, the lesser genetic change. B. A bootstrap value of 90-100 indicates a weakly supported clade. C. Neighbor-Joining and Maximum Parsimony does not consider convergence as an influencing factor in creating an evolutionary tree. D. Phylogenetic analysis treats each base of a sequence as a molecular character for analysis. Both C and D are True statements. Both B and Care True statements. None. All of the statements are False.arrow_forward
