@ThaBeatConductor Yes this is the issue with the word best . Best for humans perspective? Best in spectrum of light and sound (which part of the spectrum?) Best in physical ability? Such as eyes moving sideways or even backwards. Agree the word best is subjective. When humans have 20/20 vision, that's already counted as the best the human eye can do. Plus its quite common with children and younger adults to have this best eyesight. To get better (subjectively) then clearly the physics of the eye itself would need to change. It reminds me when theists (commonly) refer to humans (or their man) evolving better that other animals. But evolution is not about bettering at all, if anything every single lifeform known is perfectly equally evolved at any single point in time to any other known lifeform. Thus evolution is not bettering at all. Best eyesight/hearing/smelling etc? Basically that's most of the population with special emphasis on the youth.

@ThaBeatConductor Ok, true I had no idea what 20/20 vision actually meant :)
