Vaccines "were linked" to autism, too. The very "scientific" war being waged right now with our daily lives can be directly linked to the supposed link to autism.
Science is the latest, greatest religion, and I do not worship at its altar. AFAIC, "proof" of anything is elusive at best, "evidence" is the best one can get, and my suspicion and doubt have grown to epic proportions.
Firstly, yes, snow goggles are to prevent snow blindness in the spring. Winter is a L O N G period with no light whatsoever. The sun goes down in mid-November and doesn't come back up for three full months. In summer the snow is gone, so goggles are not needed. The point is that Inuit eyes didn't evolve to deal with the extreme of darkness, but with the extreme of light.
Secondly, Neanderthals living "deep within caves and forests" is assumed. Their bones have been found in caves, but so are the bones of all other predators of the era. Caves provide the better conditions for fossil and artifact preservation. As the life of a nomadic hunter/gatherer would demand, Neanderthals hunted/gathered in the forests, steppes, mountains, seashores, tundra, etc. Accepting the theory of darkness because of habitat while simultaneously rejecting Danny Vendramini's "Them & Us" theory of nocturnal hunter evolution is extremely weak.
