The Three Main Races (from a biological standpoint)

The Three Main Races
Okay, so lately I have been seeing a lot of things claiming that there is no such thing as race??? Such as: 
“Researchers have proven, scientifically, that humans are all one people. The colour of our ancestor’s skin and ultimately my skin and your skin is a consequence of ultra-violet light, of latitude and climate. Despite our recent sad conflicts here in the U.S. there is really no such thing, scientifically, as race. We are one species. Each of us is much more alike than we are different. We all came from Africa…” - Bill Nye
Yes, I know, this is Bill Nye, whom every American seems to love, however, this is absolutely IDIOTIC, and even more-so, this is SCIENTIFICALLY INCORRECT!!! There are DEFINITELY races. Anyone who has studied anatomy, and/or in my case, forensics, KNOWS there are different races. Each race (white, black, Asian, AKA Caucasoid, Negroid, and Mongoloid) has various different structures such as bones, muscle, and even HAIR structure all the way down to a microscopic level!! Mongoloid hair is thicker and when cut on a cross-section, is straight and circular, and the pigment granules are densely distributed. With Caucasoid hair, the cross-section is straight and tends to be more oval-shape, with pigment granules that are small and evenly distributed. And lastly, with Negroid hair, it is more fragile, and on the cross-section it is kinky and FLAT,and the pigment granules are densely distributed and clumped together. That’s not even going into BONE STRUCTURE. For some picture examples of this, here are some examples HERE
When it comes to bone structure, it is easiest to focus mainly on the skull, because these are the most obvious differences. Here is a link to my original, showing the images: http://lightshadow666-88.tumblr.com/pos ... main-races


I’ll focus mainly on the obvious features; the features that you don’t need to have studied Forensics or Human Anatomy to see.
EYE SHAPE: Caucasoidal: is Angular and Sloping; Negroidal is more square, or rectangular; and Mongoloidal is rounded and non-sloping.
NASAL (Nose) INDEX AND SHAPE: Caucasoid is Narrow and Tear-shaped; Negroids are rounded and wide; Mongoloids are Intermediate and Oval-shaped.
ZYGOMATIC ARCHES (Cheekbones): Caucasoid is Narrow and Retreating; Negroid is medium to large, and retreating; and Mongoloid is projecting (protruding).
OVERALL SKULL SHAPE (FOCUSING ON TOP OF SKULL): Caucasoid from the front is kind of a rounded square; Negroid is very angular; and Mongoloid is more rounded.
As you can see, it is VERY obvious that there is a lot more besides skin tone going on when it comes to race.
