Please just solve question 5, thanku! 2.Clades can be described as "natural groups."Why do you Bthink this is so？ 3.What do the“tips"and“branches"of a phylogenetic tree represent？ 4.Describe how you“trace ancestors back through time"on a phylogenetic tree. 5.Compare and contrast traditional and phylogenetic classification systems. (a）What are the advantages and disadvantages of each？ (b)Think of an example of when it would be useful to use a traditional classification.Why would this system be the best choice in this case？ (c)Think of a situation where it would be useful to use phylogenetic classification system.Why would this system be the best choice in this case？ 6. Traditional and phylogenetic classification systems usually place species in the same groups. For example，both systems place lions and tigers together，and horses.
For novice biologists, taxonomy and phylogenetics are difficult concepts to understand and keep separate. This confusion is made worse because modern taxonomic methods make use of molecular tools. Write an essay that contrasts taxonomy to phylogenetics and explain how both disciplines are important to our understanding of species and evolution. Your essay should include a description of taxonomy and phylogenetics, as well as a detailed explanation about how information is represented in a phylogenetic tree or a cladogram.
In a cladistic analysis, a systematist groups together organisms that share: derived homologous traits. derived homoplastic traits. ancestral homologous traits. ancestral homoplastic traits. all of the above.
A scientist is attempting to a cladogram that shows the evolutionary closeness of three organisms in relation to humansAfter doing DNA analysis, they that the organisms share the following percentages of DNA Organism A and humans share 85% of their DNA Organismn and humans share 80% of their DNA Organism and humans share 90% of their DNA Based on informationwhich order should they go on the cladogram ( related to most related ?
Define the following terms: -phenetics -cladistics -phylogenetic tree -clade -cladogram -phenogram -phylogenetic divergence
Cladistic methods: a. have distinct criteria for recognizing genera versus species. b. rely equally on all traits that can be measured or observed. c. cannot be used below the level of the species (e.g., to identify races). d. classify organisms based on shared ancestry e. all of the above are correct
Choose about the cladogram/phylogenetic tree/evolutionary steps of plants, or animals or chordates - write those 4 steps and what organisms share those characteristics
Which best describes traditional classification? * a. It is based on shared characteristics. b. It is based on evolutionary relationships. c. It is called phylogenetic classification. d. It is called cladistics 2. Circle the letter of each sentence that is true about evolutionary relationship of organisms? * a. DNA evidence shows that the giant pandas are more closely related to raccoons than bears. b. Scientist infer that the species with similar body structure and development patterns inherited many of the same genes from acommon ancestor.a c. Scientist never have to change their hypotheses about species relationships. d. Scientist can compare protein structure to determine how closely two species are related .
Follow up on Question 2. The purpose of including species D in the phylogenetic reconstruction is so that it can be used as a. an in-group for inferring the polarity of trait evolution b. an out-group for inferring the polarity of trait evolution c. an ancestral group for inferring the polarity of trait evolution d. a monophyletic group for classifying vge gene types e. None of the above

Need help what is the difference between a gene tree and a species tree? Explain in your own words how it is possible for gorillas and humans to share a genetic trait (such as a retroviral insertion) that chimpanzees do not share, if chimpanzees and humans are really each other's closest relatives. Given the lack of agreement between gene trees and species trees, how is it possible to reconstruct the true species tree?
TRUE OR FALSE 1. The science of cladistics produces a system for naming and classifying organisms. 2. The broadest categories in the system of classification, bellow kingdom level, are called phyla. 3. The only taxonomic unit that is needed to be written in entirely lower case letters are the genus level. 4. When all the organisms in one taxon comes from a single common ancestor, the taxon is considered to be monophyletic. 5. The presence of opposable thumbs in humans and other apes means that we share a common ancestor; this character shows homology. 6. When a derived character is shared by members of the clade, the process is called a symplesiomorphy. 7. Sexually and asexually reproducing organisms which includes polyphyletic groups are known as the phylogenetic species concept. 8. Sympatric speciation occurs when the formations of new species happen in the same geographic area. 9. When a tree is unrooted, it is not necessary needed to have an outgroup. 10. Derived characters are…
