25. Explain and give an example of spontaneous generation. Spontaneous generation—living things could come from nonliving materials (cloth + wheat = mice)

It took the efforts of three scientists to disprove spontaneous generation. Describe each one’s experiment. Drawing a picture may help but is not necessary. 26. Spalanzani boiled broth to kill microbes left 1 open and it spoiled, closed the other and it stayed unspoiled. People said that sealing it left out a “vital force” of life that is in the air. 27. Redi:

5 Name: ______period: _____ Date: ______Pretest Ch 14 – 16: Evolution used meat in a jar with a screen over it to show maggots came from eggs, not from the meat itself

28. Pasteur: Swan necked flasks- boiled broth in special flasks and left them open. That let the “vital force” in. They remain unspoiled to this day.

29. Miller and Urey did an experiment to show how life may have first formed on Earth. Describe their experiment and how they thought life first arose. The atmosphere contained ammonia, methane, water and carbon dioxide that made organic compounds under high temperatures

Charles Darwin set his theory of evolution on the work of other scientists. Describe each of these scientist’s ideas and how Darwin used them. 30. Cuvier Catastrophes caused extinctions at certain times in Earth’s past (theory called catastrophism)

31. Lyell 6 Name: ______period: _____ Date: ______Pretest Ch 14 – 16: Evolution He said that the process that shapes Earth’s surface are the same ones that worked in the past. (called uniformitarianism)

32. Lamarck Inheritance of Acquired Characteristics

Darwin’s theory of Evolution relies on 4 points. Explain each: 33. overproduction of offspring More babies are made than will survive

34. genetic variation In a population, individuals have different traits

35. struggle to survive Individuals compete to survive (food, water, shelter…)

36. differential reproduction Only organisms that are best adapted to their environment will survive and reproduce

There are many pieces of evidence for the modern Theory of Evolution by Natural Selection. Explain each of these: 37. Fossil evidence  different organisms lived at _different_ times.

7 Name: ______period: _____ Date: ______Pretest Ch 14 – 16: Evolution  today’s organisms are _different_ those of the past.  fossils found in adjacent layers are _more_ like each other than organisms that lived in widely separated time periods.  by comparing fossils and rocks from around the world, we can infer _when_ and _where_ different organisms existed.  Species have differed in a _gradual_ _sequence_ of forms over time.

38. Biogeography

• Study of the locations of organisms around the world • Organisms seemed closely related yet were adapted to different environments in nearby regions • Yet some organisms seemed unrelated and had similar adaptations

39. Anatomy

• the study of the body structure of an organism • Homologous structures- similar structures with common ancestorsà diff functions • Analogous structures- related functionsà not derived from the same ancestral structure • Vestigial structures- no longer have function

40. Embryology the study of how organism develop

41. Biological Molecules More the base sequence is similar; the more closely related the species are

Evolution can happen in several different ways. Explain and give an example of each of these: 42. Convergent evolution Different species evolve similar traits(analogous structures)

43. Divergent evolution 1 ancestor evolves into many others (homologous structures)

44. Adaptive radiation

8 Name: ______period: _____ Date: ______Pretest Ch 14 – 16: Evolution 1 species evolves to fit many different niches (purposes) in an ecosystem

45. Artificial Selection Traits are chosen to be passed on (e.g.plant/animal breeding)

46. Coevolution 2 species evolve together (e.g. humans and bacteria in us)
