It's beat into our heads from infancy...there are NO races...when the TRUE differences are so large that in ANY other mammal, we'd be considered different species.

ONLY whites show VARIATION. Blacks...all look black. They ALL have black, kinky hair, black skin, brown eyes, low nose bridge, protruding jaw...etc.

Asians, all have straight black hair, brown eyes, flat faces, and other similar features. N.A Indians...straight black hair, brown eyes, similar features.

There are no real differences in outward appearance. You don't see many if any blonde blacks, Indians, or Asians. You don't find many blue eyed blacks, Indians, or Asians. Why?

WHITES on the other hand, show GREAT diversity in appearance. You have brown hair, red hair, blonde hair, and everything in between. You have Brown eyes, green eyes, hazel eyes, blue eyes... You have kinky hair, curly hair, and straight hair. Dark skinned, medium skinned, pale skinned. Freckles, no freckles.

WHY? Why is there such variation among whites and so little among the other "races"?
