How do people tan? Melanin. What gives some clines darker skin tones? Presence of more melanin. Remove exposure to sunlight and the skin goes paler. Melanin. In STiD, Harrison's melanin has had different exposure to sunlight to Khan of "Space Seed".
I stand corrected re the gray hair. Could be. Could be.
But, seriously, do you really believe what you wrote above?! You're saying that a few decades spent in the ceti system could have turned Khan's skin as pale as it was in TWOK?
Anyway, it doesn't matter. I truly don't get all the handwringing over this stupid topic.
