First of all, it is important to remember adaptations are a process, rather than an automatic introduction. Adaptation is a process of members of a species passing on a superior trait that will enhance that species ability to survive within the genome it occupies. There are some animals that have darker fur color that serve to radiate heat away from the body, which serves as a cooling effect, making them better able to exist in hotter climates, such as tropical environments. Adaptations give a species a "one-up" on other members of the same species without this specific adaptation. In the process of natural selection, the members of the species that are better able to deal with the physical factors placed upon them within their genome are more likely the ones to propagate the species, passing their adaptive traits along to their offspring, who will in turn pass them on to their offspring.
