Quizplus · Accepted Answer

Chemoreceptors are likely the oldest type of sensory receptors because they are fundamental for the survival of even the simplest organisms, allowing them to detect chemicals in their environment which is crucial for finding food, mates, and avoiding harmful substances. This basic form of environmental interaction is present in primitive animals without complex nervous systems.
