A fern fossil dates back to 300 million years. All of these fossils were found in a single region. Which of the following statements is true? A. All three fossils were likely found in the same rock layer. B. The soft-bodied animal is most likely to be found in the lowest layer of rock. C. The fern is most likely to be found in the lowest layer of rock. D. The trilobite is most likely to be found in the lowest layer of rock. - ANS-B. The soft-bodied animal is most likely to be found in the lowest layer of rock. The ages of fossils correspond to their order: older fossils are found in deeper, older rock layers. Artificial selection occurs when humans A. add chemicals and other selective pressures to the environment. B. increase the rate of natural selection. C. select which organisms will breed.

Biological evolution is best defined as A. allowing only individuals with certain characteristics to breed. B. the change in genetic characteristics of populations over generations. C. random shifts in the genetic makeup of a population. D. characteristics that improve the chances of survival for a particular organism. - ANS-B. the change in genetic characteristics of populations over time. The idea of genetic change over generations, or time, is key to understanding biological evolution. In natural selection, the traits of individuals become more common when A. they have more mutations. B. they choose better environments. C. they produce more offspring. D. they don't get to choose who they breed with. - ANS-C. they produce more offspring. In natural selection, those who successfully breed the most often produce a greater number of offspring that inherit their traits, so those traits become more common.
