Adaptability is the measure of an organism's ability to change in order to adapt to a new environment. It is essentially a measure of adaptation ability. This is being able to change in order to be successful when circumstances in the surrounding environment change. This includes the ability to be able to handle new climates, diets, expectations, resources, and challenges. While humans and some species (such as coyotes and ravens) are highly adaptable, many species are quite limited in their ability to adapt and survive in a new environment.
