There is a great new documentary series from the BBC called “The Incredible Human Journey”. This informative documentary is about the journey of humankind from it’s origins in Africa. The science used is a combination of anthropology, and genetic biology. In the video, the host visits a northern Siberian village of people. Their world is very cold, and has lots of snow. During the brightest days, they will wear sunglasses to block the intense sunlight of the sun and it’s reflection off of the snow and sky. Even before modern sunglasses, they used the primitive sunglasses pictured below to block out the sun. These are called inuit sunglasses. I think this pair is very beautiful and the shape is amazing! If you want to see a short part of the documentary you can watch a small clip below, and find more in Youtube.com
