Haplogroup P: the ancestor linking Native Americans and Europeans across 1,200 generations
What separates an Amazonian indigenous person from a Western European? Genetically, barely 1,200 generations. Haplogroup P, which emerged some 35,000 years ago somewhere in Asia, is the common ancestor of two lineages that today seem opposed: Q, predominant among Native American peoples, and R, dominant in Europe and parts of Asia. Genetics reduces any claim of racial purity to just a few thousand years.
P is a mutation of the Y chromosome that appeared in the Upper Paleolithic. Haplogroups Q and R descend directly from it. The former populated the Americas some 15,000 years ago; the latter arrived in Europe with the steppe herders some 5,000 years ago, replacing earlier populations. Since then, part of the European population has claimed a supposed superiority, but the genetic map shows they are all brothers separated by an evolutionary blink of an eye.
The debate over racial identity collides with the data. Population genetics shows that phenotypic differences are superficial compared to the shared heritage. As the analysis points out, "all delusions of superiority boil down to a simple number: 1,200 generations." Beyond that figure, only the chance survival of a lineage.
How long will it take society to accept that race is a cultural construct, not a biological fact?
