Shai: I was thinking bout - the first human is a black, but Jesus cannot be a black, neither can God. But God made man in his own image... how could this be?
AlexTWC: There is a book "Eve and her seven daughters" can partially answer your puzzles. Human's appearances are changing gradually along with their environmental adaption. The modern human being ancestor started the skin color fading away process since about 100k years ago soon after they had reached the Mesopotamia. Mongolian then further bleached more skin color out since about 70k years ago after they finally migrated into far-eastern asia. Caucasian turned their skin color to be pale since about 45k years ago after they had traveled all over the Alps and invaded into the Europe region. They soon afterward wiped out the Neanderthal and CroMagnon species. Weather and terrain are two very important factors to affect the outline of human being. That is why scientists called Caucasian the "Children of Ice".
