The human eye is amazing, it can let you see in colour and in amazing detail that we have yet to match with our cameras.
How did it come about though, it would have taken ages through evolution? Also, why would we have needed an eye to start with, couldn't our other senses just get stronger.
This is my thought, what is yours?
Our eyes were developing and were very weak. Therefore, we used a form of supersonic location and then as our eye got stronger our hearing weaken. As a bat doesn't need good eyes it hasn't developed?
