Today we are going to find out what is the difference between fish and mammals. Evolution has left its mark, large and small, many patterns of life. New research shows that chewing has also evolved. Nicolai Konow’s team at Brown University found muscles that control the movement of the jaw and tongue in fish and mammals.
Konow and his colleagues have found that fish use the muscles of the tongue to push inward, while mammals use them to position food in the most suitable for crushing. Differences in chewing show that animals have diversified the way they chew and digest food and that evolution must have exerted an important role.
Fish use the muscles of the tongue mainly for the food channel the most in the mouth for processing as if the piece of food was an object on an assembly line. Mammals use the muscles of the tongue to place the pieces of food in the most appropriate for the jaw muscles can make effective use of the teeth in the work of chewing.

This distinction between fish and mammals with respect to chewing meets a specific need. In fish, the function of language is to move food quickly into his mouth, where in many species, there is a set (or sets) extra jaws that crush food. In addition, the language moves oxygenated water through the mouth to the gills to help the fish to breathe.
