4. Organisms that are best suited to their environment will most likely survive, reproduce and pass these traits on to their offspring. This principle is known by what name?

6. Who was the first person to attempt the classification of the living organisms on Earth?

7. Aristotle

8. Aristotle classified all animals into what three groups?
He classified all plants into what three groups?

9. Animals Land dwellers Water dwellers Air dwellers Plants herbs shrubs
trees

10. This branch of biology classifies organisms and assigns each organism a universally accepted name.

11. Taxonomy
Back to Game Board

12. This is a new system of classification that uses “shared derived characteristics” to show evolutionary relationships.

13. Cladistics
Back to Game Board

14. What was the problem with the system of classification proposed by Aristotle?

15. Many organisms were placed in groups in which there was no relationship with the other organisms found there.
Air dwellers: Birds, bats, flying squirrels, and insects would be classified together, but they are not very closely related to one another.

16. What is the problem with using common names when classifying living organisms?

17. Common names are very misleading and very confusing.
For example: “Starfish” are neither stars nor fish.

18. The study of the evolutionary relationships among organisms is known as:

19. Phylogeny
Back to Game Board

20. What name is given to structures that are similar in structure but different in function?
Given an example.

21. Homologous structures
The arm of a human is homologous to the wing of a bat.
Back to Game Board

22. A structure that is reduced in size, and seems to be “left over” from a previous ancestor is called a?
Give an example.

23. Example: The human appendix
Vestigial structure

24. On what did he base his system of classification?
What scientist was the first to attempt a scientific classification of living organisms in the 1700’s?
On what did he base his system of classification?

25. His system was based on structural similarity.
Carolus Linnaeus
His system was based on structural similarity.

26. How many kingdoms were in this early system of classification?
What were these kingdoms?

27. Linnaeus classified all organisms into two kingdoms: the plant kingdom and the animal kingdom.

28. Name the seven levels of classification in the system proposed by Linnaeus.

29. Kingdom
Phylum
Class
Order
Family
Genus
Species

30. In the system proposed by Linnaeus, what is the definition of a “species”?

31. Two organisms are placed in the same species when they can mate and produce fertile offspring.

32. When classifying an organism today, what additional information is considered?

33. Cellular Organization Evolutionary Relationships
Biochemical Similarities
Genetic Similarities
Embryological Similarities

34. The system of naming that assigns a scientific name consisting of two parts.

35. Binomial Nomenclature
Back to Game Board

36. What are the two parts to the scientific name?

37. The scientific name consists of the genus and the species names.
Back to Game Board

38. In what language is the scientific name written?

39. Latin
Back to Game Board

40. Describe the way that the scientific name must be written.

41. The scientific name must be written in italics or underlined
The scientific name must be written in italics or underlined. The genus is capitalized and the species is never capitalized.
