The mechanism for evolution that has a profound impact on a population that is very small is known as the "bottleneck effect." The bottleneck effect occurs when a population's size is significantly reduced for at least one generation. This can lead to a loss of genetic variation and can have long-term effects on the population's ability to adapt to future environmental changes.<br /><br />A cause of this type of evolutionary change could be a natural disaster such as a fire, hurricane, tornado, or tsunami. It could also be caused by human activities such as poaching or habitat destruction.
