That question belongs to science, not to religion. We don’t know anything about the original ethnical appearance of Adam and Eve. We know they where genetically perfect, which permitted the birth of the humankind out of only two person… to try this today it would be disastrous – also today nobody is able to life until 900 years old =’). Anyway, they transmitted all the richness of their perfect genome to their children which went to live in many different places in the world and made different cultures. In any culture there is many circumstances that slowly changes the global appearances of these people, like nature does with animals. For example, two birds from the same species may have a different size of beak according to the kind of food they have in their habitat. The same think occurs to humans. Black skin for example is not a mutation; it is a part of the humanity genome, the same genome is also in every Nordic people, but does not apply, or apply less intensively for oriental and Mediterranean people for example. My opinion is that Adam and eve had coppery skin and they looked like nothing existing today. But they also could be oriental looking. In conclusion of my post, oriental people began exactly like every other people, by slowly changing their global appearance through diverse cultural and environmental singularities.
