How can loss of Genetic Diversity can lead to extinction?
A species that is genetically diverse is more likely to survive in the event of a major change in it's environment, because of chance.

However, if a portion of the species is more adaptable to a colder climate, and a portion is more adaptable to a warmer climate, even though a climate change would mean death for a large portion, a portion would be more likely to survive.
