Owl Eyes

Scientists have found evidence that dark winters caused humans living in higher latitudes to evolve larger eyes. Brain size, presumably to process the extra optic information, also increased. Unfortunately the article doesn't specify by just how much, but, since humans have lived in such high latitudes for a comparatively short period of time, it does show how elastic our genes can be when confronted with new environmental pressures.
