All two-legged creatures or all two-legged human beings.
Indigenous, Native American cultures see all beings as important and vital to the health of one another. Indigenous people do not view themselves or humans in general as being superior to other animals, but rather simply a part of the entire ecosystem. For instance, many tribes categorize humans as animals, and refer to them as “two-legged” creatures; animals that can stand on two legs. They refer to animals who use four legs to walk as “four-legged creatures,” such as cattle, dogs, and lizards, and then there are winged ones, and finned ones, etc. A being is no better or worse than the other. Human beings or two-leggeds are indeed special. And, let’s appreciate the capabilities, capacities, and inter-dependencies of all our relations in our One Hoop of Life.
