The five well-known human senses are vision, hearing, smell, taste, and touch. The absolute thresholds of each of these senses may vary somewhat from person to person; they also differ dramatically across different species. For instance, humans have better visual acuity than rats, but poorer visual acuity than hawks. And black bears can smell a peanut butter sandwich from 18 miles away, while sharks can sense one drop of blood in a million drops of water.
Assume you have the ability to genetically engineer future generations of humans in such a way that their absolute thresholds are on a par with the best abilities found in nonhumans (eyes of a hawk, sense of smell of a shark, etc.).
What advantages and disadvantages would this present for these “supersense” future humans?
Start your discussion by speculating on how humans evolved their present sensory abilities and then deal with the pros and cons of having “supersenses
