What does 'endemic species' describe?

The term 'endemic species' is used to describe species that are native to a specific geographic area and are not naturally found elsewhere. These species have evolved in isolation in their particular environment, which often leads to unique adaptations that suit them to their local habitat. For instance, islands often have numerous endemic species due to their isolation from mainland ecosystems. Because these species have adapted specifically to their environment over time, they may have distinct characteristics that are not present in related species found in other areas. This concept is important in conservation biology, as endemic species can be particularly vulnerable to environmental changes and habitat loss since their limited distribution makes it harder for them to survive outside of their unique habitats.
