Q1. Describe the theory of common descent. Q2. Define ”homology” Q3. Please refer to attached file. Q4. Put these taxonomic groups in order from most inclusive to least inclusive. Order, Genus, Family, Species, Phylum Q5. Draw the relationship among these three organisms that is implied by their classification: (1) Asparagus, Order Liliales, Family liliaceae, Asparagus Officinalis (2) Yam. Order Liliales, Family Discoreacea, Discorea Species (3) Daffodil. Order Liliales, Family Liliaceae, Narcissus pseudonarcissus Q6. How can a hypothesized phylogeny this is implied by the Linnaean classification of a group og related species be tested? Q7. What is the function of the outgroup in a cladistic analysis? Q8. Butterflies have wings and bats have wings. Is this similarity a homology or analogy. Explain your answer. Q9. Describe two characteristics shared by all living organisms, and which are probably homologous among all organisms. Q10. What factors cause some organisms to look superficially similar despite the lack of a close ancestral relationship among them? As part of your answer, give an example of two organisms with analogous traits.
