A few of these adaptations are: Some animals, such as bison, have broad, flat-topped teeth and digestive systems especially adapted to feed on grasses. In 1.4, the addition of dung beetles lead to better distribution of nutrients thus more productivity and species diversity. For example, bison have finely tuned senses of hearing and smell, which they use to detect potential threats -- this also makes up for their comparably poor sense of sight. Today bison live in all 50 states, including Native American lands, wildlife refuges, national parks and private lands.
