Why are Europeans White?

This articles focuses on the regions of Europe and why people native to those areas are dipigmented. They portray a map of the solar UV at the surface and talk about how it matches with skin tone everywhere but Europe. They believe that it is the oceans and in particular the Baltic Sea that plays a part on why European skin tone is so pale. This dipigmentation is also seen in hair and eye color of Europeans. The baltic sea along with the growth of agriculture has lead to the depigmentation. The Baltic is the only place where the current is able to keep the area warm enough for grains to keep growing. Because of this, most Europeans stopped eating fish and meat and instead turned to grains. This caused a lack of Vitamin D in their body, with this and dim sunlight, it lead to a pale skin tone.
