@Malachi. Aside from the possibility of offending a lot of people who may have been under a different impression of what, and where they originated from, you need to get a full picture, or you are only working with a half truth, if that even. You really need to look at other sources than just one in order to get the truth, and I believe that Scientists made a determination that nearly everyone on the face of the planet are from mixed unions that have taken place over centuries of interracial coupling. There are many tribes and ethnicity's of people that were wiped out over a long period of time. This could have been due to a few factors like racially motivated hatred spurred on by people who were even more primitive in their thought patterns than even some people are today.
That's just one example. Another that has been around for a while, is the one that had people that looked similar but were not of the same ethnicity, absorb the smaller number into their tribe/s through coupling, which caused many tribes to simply vanish from the face of the Earth. Jewish people of those days, may have well had brown skin, but it does not mean that they are not the ancestors of present day Jewish people. Many Black people of this day can actually trace their ancestry back to South America, and not Africa as many believe themselves to originate. There are even some that had White ancestors but things changed over a long period of time. The same can be said of White People, or any other ethnicity in existence.
