I'm wondering melanin production is linked to climate - for familes that have lived in the uk for several generations how many more will it be for the part of the body that controls melanin start naturally to produce less as a result of environmental conditions and lightening the skin tone to deal with new climatic conditions, conversly to this how many generations did it take the average caucasion in say australia to increase melanin production to deal qith the hotter climate ooh this one might be easier to trace 9 im interested in the speed of human evolution to climate,
