My probably "overly anlytical" two cents worth:
This "study" is not within the confines of the traditionally accepted scientific method. As was mentioned earlier, the "sampling" is not even statistically significant and the variances are too large. Furthermore, hair growth is only cell regeneration. If AA hair grows slower, then are we metabolizing and regenerating cells at a slower rate? It does not add up. All hair grows at approximately 0.5 inches/month. If not, there is a greater medical issue at the core of the issue. Our growth may grow in "tighter" and not seem to be in alignment with the standard growth, but there should not be any major variances. For example, has anyone gotten a relaxer on an inch of new growth, that turned out to be actually 2 inches of hair after the relaxer stretched it out? But the basis of hair growth is biochemistry, not race. Fundamentally, science has proven that race is just a myth used for political posturing and the like. Statistically, there is more variation within each race than between races.There are dominant and recessive genes, but there are not many scientific differences between races.
True...and well explained

:
DUH!! Secondly, that would make African Americans become ANOTHER race, which isn't TRUE!!! Even Hispanic is not yet a race, let alone AFRICAN American! The heck? There are only FIVE races on earth that has been classified and agreed upon: CAUCAZOID, MONGOLOID, AUSTRALOID, (CONGOID, CAPOID) -> NEGROID. Now, ANYTHING aside of those is an admixture.
As far as I am concerned, ALL african americans are AFRICANS. PERIOD. Believe it or not, take it or leave it, read it and weep. It's a FACT. I am African and I cant stand it wen african americans, just because i was "born" in Africa, try to act like there is something "different" about me wen I LOOK just like them!! I have kinky hair, dark skin, big jaws, big lips, plenty of admixture, JUST LIKE THEM!!! it jes gets me SOOO MAD!!
WHAT THE F
