To those who actively explore anthropology, history and genetics, the whole speculation and debate on race topic might be irrelevant altogether, and additionally, loaded with misinformation. Most scientific discussions on race seem to have to do with the physical structure of the human body, rather than skin pigmentation, and in particular, the human scull. Excavations and research of ancient tombs have brought a lot of new discoveries into light, challenging a lot of previously recorded history.

these bi-racial twins were born to a white mother and black father. they are extremely rare.

A commonly discussed example of what genetics can do in one generation are the biracial twins Kian and Remee Hodgson. Born to mixed race parents, one of the girls is black, while the other sister is white. The girls’ parents were both reportedly born to a black father and a white mother. A source stated this case to be a one in a million chance.

Among the many mysteries are the reported presence of Y-chromosome Q at a high level in Iceland and Norway. The paternal Q lineage, suggested to have originated in Central Asia, is said to be the predominant Y-chromosome among Native Americans and is also found at high levels among tribes in Central and Northeast Asia. Another “rogue” lineage in Iceland is the Mitochondrial DNA (X chromosome) C1E, whose other identified C1 relatives are among Native American populations as well. Some have suggested that it could be traced to the Viking era, while to others, when looking at certain mutations, there might be an even more complicated story.

While Iceland has a highly advanced registry of genealogy, there are still unsolved puzzles. Many cultures might also have secrets attributed to relations that were or are considered inappropriate, perhaps illegal, denied paternities, illegitimate children, secretly being with someone from an enemy country.
