If you mean other species that would be regarded as more intelligent with a much more developed brain than the human species which I think there aren't but let's assume, then maybe humans can actually be considered by them as bioindicator species. Bioindicator species are species whose presence, absence, abundance and functions within an ecological community indicate something about the quality of the environment. For instance, frogs and toads are used to assess the level of pollution in their environment as their skins and gills have the ability to absorb harmful chemicals compounds around them. As we are witnessing man's current increasing and alarming rate of destruction of the environment, I can say that man is an indicator of environmental degradation. Humans wherever they are found always alter the state of the environment to suit themselves.
