Not sure about everything, but what I do know is the people from Africa did reach all four corners of the planet including the americas & became known as the Xi people later called the Olmecs(Rubber People) by there Mayan cousins. The Olmec are the first civilization known to most renowned scholars & people around the world. Researchers like Dr. Ivan Van Sertima, Dr. Clyde A. Winters, & several others proved beyound A shadow of A doubt that not only were the Olmecs from West Africa(Mandé) by physical characteristics, culture, linguistics, writing, calendar & several other solid facts, but they brought the rubber acasia tree(rubber tree) & the basenji dog with them as well. Because of the methods that researchers like Dr. Van Sertima & others used, they were deemed Afrentricist by racist european & american societies for going around their standardized methods & practices when in fact Dr. Van Sertima & others were not Afrocentric @ all, but studied the History Of Africa & it lead him to the Americas. It is A well known documented fact that the Washitaw & Yamasee are direct descendants of the Olmecs who are the oldest people in North America & I believe the Choctaw are related as well, but I'm not sure about the Cherokee or any of the Iraquois Nations, because they spoke A whole different language & had A different culture although my Grandfather(Father's Father) was full-blooded Tsalagi(Cherokee) & was A dark man with jet-black curly hair(like mines, but jet-black) & looked Samoan, Hawiian or Phillipeno, but could easily pass far A socalled Black person in america. Now as far as the Blackfeet, Pequot & Mohegan who are all Algonkian or Algonquian I can definitely believe it, because I'm Pamunkey(Powhatan Nation) from my mothers side & I was trying to learn our now extinct language, so I went back to the source of where all us Algonkians come from & know them as the Grandfather Clan & that is most definitely the Lenni Lenapé. I was trying to learn the language of my people when I found that A lot of the words sound Semetic, so I started to compare them & low behold, right in my face I learned that some of the words were nearly identical? I did alil bit more research & found that not only were they simular, but ironically they spoke A dialect of Manding or Mandé(West African) as well? From there, that took me on A mission to find out the origin of my Powhatan Nations people & Lenni Lenapé people & its leading me right back to no other than the Olmecs. I have always wondered why both my full-blooded Grandfathers are so dark, but I think I might be closing in on it? Scratch my head? A lot of our peoples are white-washed & are very racist towards socalled Blacks, Whites & even our own mixed-blood Natives such as myself(Mostly whom are mixed with Black), but there is A good reason for that although we might not ever know?
