[Davy Crockett]

From the linked article:

As the National Geographic Society’s Genographic project makes clear, all people on Earth today share a direct common ancestry. We all came from Africa about 60,000 years ago. After walking north from Africa, some of our ancestors turned left and migrated to Europe. Others turned right and populated Asia, then Siberia, then America. In fact, the DNA evidence is conclusive that everyone alive today shares a common great-great-grandfather and a common great-great-grandmother – with many “great”s added......
......Everything I said above is well known to researchers and authors in anthropology, genetics, sociology, and any related field. But the scientific fact “race does not exist” is not common knowledge among the general public.

Further down this writer admits:

My daughter’s biological parents live in a different culture than my family. Stating that obvious fact is different, however, than asserting that we are of different races. My daughter from China is really a distant relative to my Irish wife and me, with the same African ancestors.

Now here is an unbiased look at the real science:
