An article in Science Daily described the research ongoing at Brown University concerning the evolution of the tongue in different organisms. Every organism has their own way of getting the nutrition they need in order to survive. Specifically, fish, mammals, and amphibians were used in their research. They all used their tongue for the process of digestion, but in different ways.
Research at Brown University found that fish use their tongue in order to thrust food backwards further into their system. On the other hand, mammals use their tongue for better placement of food in the mouth to chew.
The researchers were curious as to where the split in evolution took place between the two types of tongue movements. Amphibians seemed to be the answer because of their tongue characteristics which Brown University plans to further research.
