The sensory system comprises the visual, auditory, olfactory, taste and the body senses. Evolution would propose that each sensory system is of significant significance to maintaining the human organism. For this discussion, assume you are a professor giving a lecture on the evolutionary significance of the sensory systems. Make a summary of your argument. Recognize which is the most significant sensory system for human survival. Your discussion must also point out which system is least significant from the viewpoint of the 'survival of the fittest'. Your initial post must be a minimum of 250 words and employ at least one peer-reviewed source that was published in the last five years.
