Summary Introduction
Introduction: In the Linnaean system of taxonomy, the related genera are placed in the same family— related families into orders, orders into classes, classes into phylum, phyla into kingdoms, and kingdoms into domains. The domains bacteria and archaea consist of single-celled prokaryotes, which differ in several characteristics. The domain eukarya includes all the eukaryotes such as animals, plants, and

- Which of the following is a prediction that evolution makes about the fossil record? Group of answer choices A. fossils of all time periods should be completely different from modern organisms B. most recent fossils should be most similar to modern life C. cats should appear in all fossil layers as rulers of the earth D. oldest fossils should be most similar to modern lifearrow_forwardRefer to figure 13.25 and the chapter content to answer the followingquestions.1. Review the Survey the Landscape figure in the chapter introduction.What diagrams do scientists use to visualize evolutionaryrelationships? Add this term to the concept map. 2. Write a phrase to connect fossils and biogeography and a separatephrase to connect development and DNA. 3. Add the following terms to this concept map: homologous structures,vestigial structures, homeotic genes, and molecular clock.arrow_forwardWhich 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_forward
- An analysis of a phylogeny that displays data about the fossil record over time reveals all of the following EXCEPT A. Several extinction events occurred. B. Evolution results in a clear directional pattern. C. Evolution is the result of interactions between organisms and their environment. D. Evidence of continental drift exists.arrow_forwardWhich of the following is an accurate point that supports the idea that the earliest protocells relied first on RNA (not DNA) as inherited information? A. RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D. RNA can serve dual roles as both genetic information storage and an enzyme (but DNA cannot do both) ..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_forward
