Comments by "Jack Mac" (@TheEggmaniac) on "Why Do Inuits Not Have Blue Eyes? The Reason for Blue Eyes (Part 2)" video.

There are theories on why blue eyes developed in humans. Bu there has been no scientifically proven reasons. I think one of the most likely theories is it was seen as attractive in partners. So it was passed on by selective mating with partners who had blue eyes. I dont there is any actual evidence of a blue eyes having greater sight, in areas with lower levels of light. Though they may have more sensitivity to light. Not always a good thing. Lighter skin definitely gives someone advantages at higher latitudes with less light. It make them more sensitive to light and more able to produce vitamin D with lower levels of light. The explanation for Inuit not having pale skin colour, is because they have a diet which has traditionally included a lot of seafood and sea mammals that are high in vitamin D. So they dont need to have lighter skin to be able to to absorb vitamin D more efficiently than darker skin tones. However eye colour is not connected to skin tone. More likely the ethnic group the Inuit descended from, never had the genes for blue eyes in it.
