>>509111793 (OP)>What caused them to evolve like this? What evolutionary benefit does this provide?The extremely bitter cold of Siberia, which was even more harsh during the ice age. Just as niggers in Africa evolved to adapt to the heat, Asians evolved to adapt to the bitter cold.
Those epicanthic eye folds confer an advantage in harsh cold, because your eyes will freeze otherwise.
The Keratin in their skin which makes their skin yellowish also helps with heat retention.
Asians also evolved to have dry earwax because again wet earwax would freeze.
Basically, they're anti-Niggers.
