1) Speciation, or the formation of new species, is A) necessary for natural selection and adaptation. B) an event that has occurred only a few times in the history of the planet. C) a form of microevolution. D) responsible for the diversity of life. 2) Under the biological species concept, a species is a group of organisms that A) live together in a location and carry out identical ecological roles. B) have the potential to interbreed in nature and produce fertile offspring. C) are physically similar. D) share a recent common ancestor. 3) Microevolution, or evolution at its smallest scale, occurs when A) an individual's traits change in response to environmental factors. B) a population's allele frequencies change over a span of generations. C) a community of organisms changes due to the extinction of several dominant species. D) a new species arises from an existing species. 4) Which of the following types of reproductive barriers separates two flowering plant species that could interbreed but for the fact that one has a deep flower tube and is pollinated by bumblebees whereas the other has a short, narrow flower tube and is pollinated by honeybees? A) mechanical isolation B) gametic isolation C) habitat isolation D) behavioral isolation 5) The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. The Monterey pine releases pollen in February, while the Bishop's pine does so in April. This is an example of isolation. A) postzygotic B) temporal C) habitat D) mechanical 6) The geographic isolation of a population from other members of the species and the subsequent evolution of reproductive barriers between it and the parent species describes speciation. A) punctuated B) sympatric C) allopatric D) biogeographic 7) Speciation without geographic isolation is called speciation. A) sympatric B) allopatric C) diversifying D) incomplete
