Genetic Diversity
One superpower species have to adapt to environmental changes is genetic diversity. Generally speaking, the bigger the population, the more genetically diverse it is. That’s because more individuals mean a wider variety of inherited traits, such as fur color or body size, giving them a bigger genetic toolbox to adapt to a changing environment.

Introduced Disease
When a disease is brought to a location where it wasn’t previously present, it is considered an introduced disease. Introduced diseases typically have a bigger impact on wildlife than native diseases, because exposed species haven’t had time to evolve natural defenses to fight off the novel pathogens.
