2. Male dragonflies of one species are unable to grasp the abdomen of female dragonflies of a different species securely enough to mate, due to poor alignment of the four wings on each insect. This type of interference during mating attempts between different dragonfly species is: A. an example of a pre-zygotic barrier due to behavioral isolation B. an example of a pre-zygotic barrier due to gamete isolation C. an example of a pre-zygotic barrier due to mechanical isolation D. an example of a pre-zygotic barrier due to habitat isolation E. an example of a pre-zygotic barrier due to temporal isolation

1. The North American garter snake (7hamnophis) has a number of sympatric populations that can be either terrestrial or aquatic. Terrestrial populations generally do not interbreed with aquatic populations, despite living in sympatry, because they are most likely separated by which pre-zygotic barrier? A. allopatric isolation by means of vicariance B. gamete isolation C, mechanical isolation D. habitat isolation E. allopatric isolation by means of dispersal 2. Male dragonflies of one species are unable to grasp the abdomen of female dragonflies of a different species securely enough to mate, due to poor alignment of the four wings on each insect. This type of interference during mating attempts between different dragonfly species is: A. an example of a pre-zygotic barrier due to behavioral isolation B. an example of a pre-zygotic barrier due to gamete isolation C. an example of a pre-zygotic barrier due to mechanical isolation D. an example of a pre-zygotic barrier due to habitat isolation E. an example of a pre-zygotic barrier due to temporal isolation 3. Macroevolutionary events in the fossil record include all of the following, except the origin of: A. Didelphis virginiana from the South American opossum (Didelphis marsupialis) B. the dog (Canis lupus familiaris) from the gray wolf (Canis lupus lupus) C. the grazing proto-horse from the browsing near-horse (Parahippus leonensis) D. the first bird (Archaeopteryx lithographica) from theropod dinosaurs E. new world monkeys (platyrrhines) from old world monkeys (catarrhines) 4. The origin of the proto-horse (Merychippus gunteri) from the near-horse (Parahippus leonensis), from about 23 million to 17 million years ago, illustrates which of the following selection patterns? A. directional selection leading to anagenesis B. stabilizing selection leading to stasis C. disruptive selection leading to branching speciation D. diversifying selection leading to cladogenesis E. all of the above 5. Darwin's finches evolved into many separate species on the Galapagos Islands, with the Pacific Ocean as a barrier to their interbreeding. Since the Pacific Ocean was a barrier between these islands before the ancestral finch first arived, this represents which of the following pre-zygotic barriers? A. allopatric isolation by means of vicariance B. gamete isolation C. mechanical isolation D. habitat isolation E. allopatric isolation by means of dispersal
