Plz answer seperately
- Bhakti (age 14)
It's because if you have only one of each you cannot get any depth or direction information. You can only tell that something is out there but you don't have any clue to where (for sound) or how far (for light) the source is. This is an evolutionary advantage.
Also, given the trials and tribulations of life, having a spare is a good idea.
