  1. Blue Eyes An Evolutionary Adaption To The Climate And Vegetation Of Northern Europe Low light intensity in the winter in Northern Europe. Dense cloud cover end dense precipitation that both reduce the light reaching the earths surface. The historic vegetation cover of Northern Europe is Oak Forest and dense Oak Forest reduces the light reaching the earths surface below the Oak Forest. Combine the above variables and the intensity of sunlight reaching the earths surface is vastly reduced. Thus blue eyes are more sensitive to low intensity sunlight so will be a biological adaption to the climate and vegetation cover of Northern Europe. Important --- Dense cloud cover and dense precipitation vastly reduces sunlight reaching the earths surface. However dense drizzle will reduce sunlight reaching the earths surface more than dense rain. In the Atlantic Climate Zone and to an extent the countries around the Baltic Sea dense drizzle is frequent precipitation thus this type of perception being Dense Drizzle vastly reduces sunlight reaching the earths surface thus blue eyes will proliferate in regions of Northern Europe that experience frequent Dense Drizzle precipitation. Blue eyes originate from present day Latvia? Latvia is where the historic vegetation cover changes from Dense Oak Forest to Pine Forest. In the region of Northern Europe covered by Pine Forest Grey Eyes proliferate. Correlation or Causation? Dense Pine Forest and grey eyes? Western Hunter Gatherer -- Blue Eyes Eastern Hunter Gatherer -- Brown Eyes Latitude light intensity is stable thus this is constant and can be ignored. Vegetation cover is stable with latitude thus a constant and can be ignored. However cloud density and density and type of precipitation is a variable and must be factored in to explain eye colour. Western Hunter Gatherer Region Density of cloud cover and density of precipitation and specifically dense drizzle is a different type of precipitation to the Easter Hunter Gatherer Region. Dense cloud cover and Dense Precipitation and specifically a very dense Drizzle vastly reduce sunlight reaching the earths surface. Is this the reason for Western Hunter Gatherers having Blue Eyes? My opinion is the evidence is overwhelming. Comments welcome ===== ===== Pine Forest And Grey Eyes Dense mist being micro droplets results in very little light reaching the surface of the earth. Grey eyes due to the dense mist the climate creates in the region where grey eyes proliferate in the extreme north of Europe? A dense mist will block significantly more light than a dense drizzle from reaching the earths surface. My opinion is this is the reason why grey eyes proliferate where they do in the extreme north of Europe being the dense mist made of micro droplets results in so little light reaching the earths surface.. Dense mist added to northern European latitude and the pine forest combined results in very very little light reaching the earths surface. The core issue is the dense mist made of micro droplets. ==== Grey Eyes --- Extreme North -- Dense Cloud Cover and Dense Mist of Micro Droplets Blue Eyes --- Far North -- Dense Cloud Cover and Dense Drizzle of Mini Droplets Green Eyes --- North -- Dense Cloud Cover and Dense Rain of Droplets Thus climate variables correlated to different eye colours.
