    Change is the rule, though much depends on the speed and degree of the change. When the habitat changes, three main things may happen to a resident population: habitat tracking, genetic change or extinction. In fact, all three things may occur in sequence. Of these three effects only genetic change brings about adaptation. When a habitat changes, the resident population typically moves to more suitable places.

    Earthquake Detectors

    Soviet scientists believe that earthquakes can be predicted by studying the behavior of snakes, worms, and other animals. Certain organisms are said to respond to the geomagnetic vibrations and to temperature and water-level changes that precede earth tremors. According to scientists, it may be possible to analyze animal behavior with the aid of a computer and thus accurately predict earthquakes long before they happen. For example, studies have disclosed that about one month prior to a strong earthquake, snakes will crawl out of their nests and abandon a dangerous zone. Scientists believe that the sensitivity of these animals greatly exceeds that of modern man-made earthquake detectors.
