sensory systems

This week you were introduced to the sensory systems which include the visual,
auditory, olfactory, taste and the body senses. Evolution would suggest that
each sensory system is of significant importance to maintaining the human
organism. For this discussion, imagine you are a professor giving a lecture on
the evolutionary importance of the sensory systems. Prepare a summary of your
argument.  Identify which is the most important sensory system for human
survival. Your discussion should also indicate which system is the least
important from the perspective of the “survival of the fittest”.  Your initial
post should be a minimum of 250 words and utilize at least one peer-reviewed
source published within the last five years
