- Which of the following serves as an advantage to using numerical taxonomy? a. Trait choices are arbitrary. b. All traits are weighed equally against one another. c. Visual traits, like cell cell shape and size, are the most important criteria for determining similarity between species. d. Traits and activities of different bacteria are informative, and considered with this approach.arrow_forwardA branch points on a phylogenetic tree is where scientists that study systematics place a groups organisms that share the formation of a new character. b organisms that have not yet diverged. c the emergence of a new genus. d the root of a phylogeny.arrow_forwardWhich of the following describes systematics?a. studies evolutionary relationshipsb. includes taxonomy and classificationc. includes phylogenetic treesd. utilizes fossil, morphological, and molecular datae. All of these are correct.arrow_forward
- Which of the following statements is incorrect about the rules in biological nomenclature?arrow_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_forwardShould more weight should be given to genetic data or to information derived from comparative anatomy (phenotypes) in regard to taxonomic classification?arrow_forward
- 1) How have scientists created the "tree of life"? Do you think that variations exist between these created trees? 2) What are the pros and cons to creating a "tree of life"? 3) When constructing this tree of life we can see many dead ends or organisms that we are unsure of their exact placement. Why is this? 4) Choose one species (either alive today or extinct) and describe its taxonomic classification. What traits or characteristics were used to classify this species into its current taxonomic classification? What other organisms are considered to be its closest relatives?arrow_forwardIn 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_forward1. The taxonomic Supergroups of life are a work in progress which attempt to hypothesize on the relatedness of life's major groups. Currently this phylogeny includes a non-dichotomously branching clade with three different branches connecting to one node. The clade that includes all three branches emerging from the same node is known as A) homeoplasiac traits. B) polytomic lineages. C) paraphyletic clade. D) polyphyletic clade E) all of the abovearrow_forward
