2 Darwin’s job was a

3 Naturalist

4 Darwin is known as the father of _______

5 Evolution

6 The book Darwin wrote

7 On the Origins of Species

8 Darwin waited 25 years to publish his work because?

9 He was afraid of criticism from the church

10 Darwin’s theory of Evolution is based mainly on the idea of

11 Natural Selection

12 The Arctic fox and the Gray fox are similar to one another but live on opposite sides of the world. What does this tell you about them?

13 They arose from a common ancestor and then migrated to different parts of the world

14 The fact that the chicken, the salamander, the pig and the human all look similar during embryological development suggests that…

15 They arose from an ancient common ancestor

16 A person claims that a giraffe can evolve to have a longer neck over its lifetime, but you disagree because…

17 An individual in a species doesn’t evolve, a population does.

18 Shown below is gene flow, when an organism moves to another population and gives away its genes there. What does this do to the population it just joined?

19 The population gets new genes in the gene pool which increases the genetic variation in that population

20 These are all examples of what?

21 Analogous structures

22 Helps you survive by helping you blend in with your surroundings

23 camouflage

24 Helps you survive by allowing you to copy other organisms

25 Mimicry

26 Another phrase for natural selection is basically

27 Survival of the Fittest

28 Type of reproduction that allows for more variety

29 Sexual Reproduction

30 This type of selection is called

31 Disruptive selection

32 According to the cladogram, which animals are more closely related to the rabbits, birds or primates?

33 Primates

34 Species will have more offspring than are likely to survive. Why?

35 To ensure that at least some survive to reproduce.

36 Explain why there are only orange bacteria left. Generation

37 The resistant bacteria lived and passed on their resistant genes and the non-resistant died before reproducing.

38 A volcano erupts and ash covers the surrounding trees where the light and dark moths live. What will happen to each kind?

39 The light moths will blend and survive and increase while the dark ones will be hunted and decrease.

40 How do mutations create new species?

41 If a mutation changes a gene and becomes beneficial to the future species, then eventually the species can accumulate mutations and form a new species.

42 Type of evolution that occurs slowly over time

43 Gradualism

44 Formation of a new species is known as

45 speciation

46 The type of evolution that occurs rapidly and then there are periods of stasis (no change)

47 Punctuated equilibrium

48 Structure that is reduced in size or function but still present is known as

49 Vestigial structure

50 These are known as

51 Homologous structures
