THE TRUTH: A well excepted theory why orientals have slanted eyes is not a result through "adaption" and has nothing to do with sunlight, winds, etc..
There are more than one way to explain evolutionary differences and geographical evolution is the answer to the slanted eyes. NOTHING HAVING TO DO WITH SURVIVAL OF THE FITTEST OR ANYTHING LIKE THAT IS THE REASON, its the "common ancestor" that was 1st to be in Asia had slanted eyes due to CHANCE. Yes, like having webbed feet or a widows peak, which have NOTHING TO DO WITH SURVIVAL is the same reason why the earliest decedent of Asians had slanted eyes. DNA recombination, crossing over, all have supporting info about the "chance" fact.
Genes in which NEVER APPEARED before can UPRISE from nowhere just base on chance, it is a fact. Long story short (millions of years)
Asians breed with each, other several climate factors took place, ppl migrated, and now slanted eyes are dominant genes thus giving a distinct, all exclusive gene to Asians. African Americans skin tone and European beards are PURELY adaptation, which is in fact TRUE but NOT with SLANTED EYES.
