33) The similar embyrology of birds and humans indicates that they A) have the same amount of DNA B) are in the same species C) have a common ancestor D) have analogous structures 34) Which of the following is NOT a homologous structure of the other three? C) arm of human D) forelimb of a horse A) wing of a butterfly B) foreleg of a lizard 6737-1 - Page 7 35) Certain strains of bacteria that were susceptible to penicillin in the past have now become resistant. The probable explanation for this is that A) a mutation was retained and passed on to succeeding generations because it had a high survival value B) the mutation rate must have increased naturally C) the strains have become resistant because they needed to do so for survival D) the principal forces influencing the pattern of survival in a population are isolation and mating

C) arm of human D) forelimb of a horse 37) A) wing of a butterfly B) foreleg of a lizard 38) 35) Certain strains of bacteria that were susceptible to penicillin in the past have now become resistant. The probable explanation for this is that 36) Change to the Earth's physical structure over time is A) a mutation was retained and passed on to succeeding generations because it had a high survival value B) the mutation rate must have increased naturally C) the strains have become resistant because they needed to do so for survival D) the principal forces influencing the pattern of survival in a population are isolation and mating A) organic evolution B) not possible C) have a common ancestors (A D) have analogous structures o The study of mutations is important to the modern theory of evolution because it helps to explain A) differentiation in embryonic development B) the extinction of the dinosaurs Mainland C) geological evolution D) the result of extraterrestrial involvement Nesting region Normal migratory Thousands of years ago, a large flock of hawks was driven from its normal migratory route by a severe storm. The birds scattered and found shelter on two distant islands, as shown on the map below. The environment of island 4 is very similar to the hawk's original nesting region. The environment of island B is very different from that of island A. The hawks have survived on these islands to the present day with no migration between the populations.

A) The hawks on island A have given rise to many new species. B) The hawks that landed on island B have evolved more than those on island A. C) The populations on islands A and B have undergone identical mutations. D) The hawks that landed on island A have evolved more than those on island B. 0
