Second Wave of English Jews to the Colonies


The second wave of Crypto-Jewish immigration to the American colonies was radically different from the earlier wave, though only separated by 50 years. These colonists were primarily descendants of Jews who stayed in Spain and Portugal after the Edict of Expulsion (1492) and converted, or pretended to

Jewish Musicians


In part two of this paper, I will focus on one segment of the secret Jewish community of London that cannot be overlooked…… musicians. They were in a sense, a nation in and of themselves.

Private Alleles Reveal Minor Ancestry


It is widely accepted that STRs are non-coding in nature and are therefore not implicated in gene expression. By the same token, scientists used to think that single variations in the number of repeats (STRs) in your autosomal profile could not be correlated with population or ancestry, that you needed at least four STR alleles to reach meaningful conclusions.

Did the Kon-Tiki Sail in the Wrong Direction?


I recently reread Stephen Oppenheimer’s classic detective story, Eden in the East: The Drowned Continent of Southeast Asia. To recap briefly its conclusions, the famous Oxford geneticist dissects the folklore motifs of the Biblical story of the Garden of Eden, Noah’s flood, the Tower of Babel, Tree of Knowledge and Cain and Abel and traces them back to Sundaland, a region once the size of North America , now a submerged shelf of land in the South China Sea.

A Real Indian Belongs to a Federally Recognized Tribe—a Wannabe Doesn’t


That is the take-away from an academic study often cited by people denouncing “pretendians.” Becoming Indian by Circe Sturm appeared several years ago as a blue ribbon publication of The School for Advanced Research in Santa Fe, N.M. It is likely to be used and cited widely by schoolteachers, tribal educators and government workers.

Don’t Take Any Wooden Nickels


After pioneering a distinctive ancestry method centered on our population database atDNA, starting more than 20 years ago, DNA Consultants has had surprisingly few competitors. One newly minted operation that has recently entered the fray, howev
