Evolution of the Bitter Receptor in Sharks: How Taste Buds Helped Sharks Survive
The evolution of taste is an ongoing process, and a recent study has revealed new insight into the evolution of one particular type of taste receptor. Researchers from the University of Massachusetts Medical School and the University of Hawaii have discovered that a bitter taste receptor in sharks evolved from a receptor that was previously used to detect changes in water pressure. This adaptation is believed to be an evolutionary response to the changing ocean environment and an important factor in the survival of sharks. The findings of this study have implications for how we understand the evolution of taste in other animals.
