It is very interesting to read from you. I strongly agree with your findings on origin for African Americans. Sometime ago in 2002 and after, I worked with Dr. Rick Kittles at Howard University sequencing DNA from different tribal groups from Nigeria, Ghana, Liberia, the Caribbean and even from Cameroon thanks to the efforts of professor Angwafor from CUSS in Yaoundé. Beyond that, as a DNA forensic expert witness, we always report statistics for three major populations, Caucasian, African American and Hispanics for the genotypes of an unknown piece of evidence. The science of DNA is true and informative but hardly is it used exclusively for conviction in a court of law in the US. I appreciate your piece on this".
Some people argue that most Black Americans have the same accents, so it will be difficult to use ortheopic methods to discern their genealogy. That is not true. In exceptional cases do two people have the same accents, if we listen closely. How many people have the same voice?
