Answer to Question 1

Answer: Mutations increase the range of features or behaviors seen in the organism. Most of the time, this is harmful to the organism or to its reproductive fitness. Very rarely, the mutation results in a feature or behavior that increases the fitness of an organism; in these cases, the mutation is likely to become part of the preferred genetic makeup of the species.

Answer to Question 2

Answer: Natural selection suggests that certain characteristics of an organism offer an advantage that allows the organism to reproduce and to pass on that characteristic to its offspring. The coloring of an organism may allow it to blend into the background, thus escaping detection by predators. The capacity to remain still (i.e., freeze) may similarly allow an organism to avoid predation.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
