ARE NEGROES / BLACKS / SUB-SAHARAN AFRICANS A HUMAN SUBSPECIES? - TARA McCARTHY

No disrespect to Blacks, or any race expressed.
Rather, scientific questions presented.

Since other animals have, and are, species and subspecies, why not humans as well?

My take, with the disclaimer, my BIO 101 and 102 college courses in no way make me an expert.

The average Caucasian and Asian have about a cup more brain than the average Negro.
I use these racial terms (Asian etc - races/breeds/subspecies), with no offense intended.
Question: How could different average brain sizes not impact IQ/intelligence?

Compassion is warranted, not hate.

Asking someone to "get smarter", is the same as asking someone to change their hair color, or just get taller.
All these traits, and potentials, are set at conception.

Beyond the basics of both a good diet and education....IQ cannot be changed. Correction, IQ cannot be increased.
We know how to lower IQ...drugs during gestation, etc.

Over 200 K - grade 12 studies in the U.S have shown, beyond the basics, education doesn't increase intelligence or school performance.
In other words, beyond a basic chair, clean classroom, and an acceptable teacher....more money solves nothing.

No species or subspecies is responsible for the evolutionary pressures that have resulted in the realities of today.
Different averages in gestation lengths, age of sexual maturity, brain size, and even ear wax and skin pH.

Did the evolution pressures that caused our largest organ, skin, to change over the a span of approximately 100,000 years, leave the brain untouched?
