@ ninja , LOL.
Remember guys that the wts has actually provided a reasonable answer regarding why we have such disparity between how humans from each continent look......
"white people living in China eventually produce Chinese offspring (without intermarrying)--due to the influence of soil and climate"
The Watchtower 7/15/ 1902.
So I would like to propose that Adam and his Wife in fact lived on all of the continents for a while and had kids there, so that explains why we all look so different. I mean they did live to nearly 1000 yrs old.......Perhaps he took some baby koala bears down to Oz in his boat after he named them too?
I think this could qualify as "new light".
