>>11920350>thinks dark eyes are for huntingThey are for reflecting light away from the pupil. The same premise as putting black paint on your cheekbones.(American football cliche).
Light eyes means melanin in the iris wasnt needed for our ancestors to reproduce.
It is a benign mutation.
If we look at animals eyes, we will see a vast array of colors. Perhaps some fill a niche.
An observation however, is that dogs bred in the snow(huskies) often have very light eyes.
Another observation, a similar species bred in the snow(the polar bear) has pitch black eyes.
Conclusion: Benign, random mutations.
We all know that after enough mutations, species will diverge. You cannot tell me I am the same species as an aboriginal, it would be preposterous.
