Beagle? 30 Title of the book written by Charles Darwin 31 What is Origin of Species? 32 Islands studied by Charles Darwin 33 What are the Galapagos Islands? 34 35 The mechanism proposed by Darwin for evolutionary change 36 What is natural selection? 37 Darwin used this phrase for individuals competing with each other 38 What is the “struggle for existence” or survival of the fittest? 39 Individuals having different traits in a population 40 What is genetic variation? 41 Man responsible for this theory 42 Who is Charles Darwin? 43 A trait that makes an individual successful in its environment 44 What is an adaptation? 45 In order to pass on traits, an individual must do this 46 What is reproduce? 47 A measure of an individual’s genetic contribution to the next generation 48 What is fitness? 49 Remains or traces of an organism that died long ago 50 What is a fossil? 51 Term that means a species no longer exists 52 What is extinct? 53 Record of when different fossils were found and organisms existed 54 What is a geologic timescale? 55 Rock strata where the oldest fossils will be found 56 What are the bottom most layers? 57 58 Anatomical structures with similar structures but different functions 59 What are homologous structures? 60 Galapagos tortoises and finches were similar to the finches and tortoises found here 61 What is the mainland of South America? 62 Scientists study this macromolecule to determine if organisms are related 63 What is DNA or nucleic acid? 64 Evolution in when species develop similar characteristics because of living in similar environments 65 What is convergent evolution? 66 Type of evolution in which organisms with similar structures develop from a common ancestor 67 What is divergent evolution? 68 When species evolve and spread out to fill all parts of an environment 69 What is adaptive radiation? 70 71 Fossils 72 Technique used to determine the absolute age of a fossil 73 What is radiometric dating? 74
