I definitely think human eyes haven't yet all evolved to their full potential. The same could be assumed for other human senses which could also be sharpened. Consider how animals can hear higher frequencies than humans. House pets seem to 'sense' when their owners are coming home. Why is it that a dog will bark when looking in the same direction as you and you may not perceive anything unusual? We may only be as limited as we believe we are. Life is all about learning to see, raise awareness and heighten perception.
