Bio Ch 17

QuestionAnswer
1. What did Carolus Linnaeus do Simplified system for naming groups of organisms
2. What is a scientific name Specific to each organism
3. How many levels of classification are there Now eight, Linnaeus named seven
4. What is a species Smallest taxonomic group
5. Can dogs and wolves interbreed Yes, very closely related
6. How does classification affect evolution Provides strong evidence for evolution
7. What is an analogous structure Same use, made differently
8. What is cladistics Determine order of evolution
9. What is a genus Second from the smallest level of classification
10. How are organisms groups under the Linnaean system Organized by form and structure
11. Which group of organisms is most abundant on earth Bacteria
12. Be able to put taxa in order (kids playing catch on freeways get squashed) Kingdom, Phylum, Class, Order, Family, Genus , Species
13. What is a molecular clock Uses mutation rates to measure evolutionary time
14. What is a clade Area between two species in a cladogram
15. How many domains are there Three
16. How many kingdoms are there Six
17. What defines modern classification Based on common ancestory
18. What is Canis lupis Binomial nomenclature, Wolf
19. Which types of evidence can we use to classify stuff Molecular is most reliable
20. What is taxonomy Science of naming and classifying
21. How do we write a scientific name Genus species, two latin names
22. What are the advantages to a scientific naming system Communicate regardless of language
23. How are animals sorted in the Linnaean system Form and structure
24. Know your taxonomic groups.
25. What is a hybrid Interbreeding between closely related species
26. Which genus has dogs and wolves Canis
27. Why is species hard to define in asexual reproducers Can’t use reproduction as a criteria

34. What is a genus First part of scientific name
35. What is a derived trait Traits formed after separation from a common ancesters
36. How has the classification system changed over time Cladistics is based on evolutionary relationships instead of physical characteristics. Molecular biology has allowed scientists to classify organisms together even if physical characteristics are not similar.
37. What new technologies are there Molecular classification
38. What are the levels of classification Kingdom, Phylum, Class, Order, Family, Genus, Species
39. How do biologists classify organisms Appearance, structure, molecular similarities and differences.
