Jews in the New World

Jews in the New World

An article in The Atlantic caught my attention. We’re going ’round again with conversos and crypto-Jews, and once again the fantasy is just as stronger or stronger than the proved reality.

In 1492 Ferdinand and Isabella ordered all Jews in Spain to convert to Catholicism or leave the kingdom. Those who converted became known as conversos. Some of them continued to practice Judaism in secret, and even if they didn’t, they were often suspected of it. The functional result of this suspicion was that many conversos took pains to hide their Jewish ancestry.

Ferdinand and Isabella commissioned the first voyage of Christopher Columbus the same year they expelled the Jews. Two grand narratives in the same year. The temptation to link them is almost irresistible.

The popular story is that Columbus himself was a Jew looking for new homeland, and the American Southwest is full of crypto-Jews who are descendants of conversos driven further and further north as the territorial government solidified its hold.

Here in Colorado we have a native Hispano population that goes back to the early days, before the Anglo-American conquest. One of my step-mothers belonged to such a family. It’s not uncommon.

What we’ve seen just in the course of my lifetime is that Hispanos throughout Colorado, New Mexico, Arizona, and Texas increasingly claim Jewish ancestry. In some circles the stories have reached a saturation point where no one doubts them anymore. They are taken at face value. In fact, there’s now a special term for them — the anusim, the one who were forced.

The modern fashion for finding crypto-Jews in the American Southwest seems to have started with Stanley Hordes in the mid-1980s. As New Mexico State Historian he heard stories that could be broadly interpreted as pointing to Jewish customs. He became convinced there was a bigger story there. After he left his job he began promoting the idea that conversos made their way to the New World, where they were able to practice Judaism in secret for 400 years. (Barbara Ferry and Debbie Nathan, “Mistaken Identity? The Case of New Mexico’s “Hidden Jews” in The Atlantic (Dec. 2000)).

In the late 1980s and early 1990s the story exploded in popularity. Now there’s even a Society for Crypto-Jewish Studies. But were they really crypto-Jews? There’s a great deal of doubt. Certainly, the Inquisition was looking for crypto-Jews. About 100 were executed in Mexico, and many more were investigated, including a governor of New Mexico.

Many experts now believe Hordes misinterpreted the stories he was hearing. What he thought were survivals of Judaism might have come instead from Catholic converts to Protestant churches that emphasize Jewish practices. The most popular of these seems to have been the Seventh-Day Adventists, who observe the Sabbath on Saturday, practice Jewish dietary restrictions, celebrate certain Jewish holy days.

DNA Color Clustering

DNA Color Clustering

This looks interesting. It also looks obvious. (So why didn’t I think of it myself?)

Unsure of how other people were sorting their Shared Matches from AncestryDNA, I developed my own method: the Leeds Method of DNA Color Clustering. This simple and quick method helps you easily visualize how your close cousins are related to you and each other.

Behavioral Genetics

Behavioral Genetics

Some of my friends think Human Biodiversity is just alt.right propaganda. Others, equally liberal and progressive, think it’s a breath of fresh air in a field overburdened with political correctness. Me, I’m an agnostic. As I often remind people, I didn’t get the True Believer Gene.

With that out of the way, Jayman has what I think is a very nice intro article, “The Five Laws of Behavioral Genetics”. He offers this summary, then goes into a little more detail about each point:

The five laws of behavioral genetics are:

  1. All human behavioral traits are heritable.
  2. The effect of being raised in the same family is smaller than the effect of the genes.
  3. substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families.
  4. A typical human behavioral trait is associated with very many genetic variants, each of which accounts for a very small percentage of the behavioral variability.
  5. All phenotypic relationships are to some degree genetically mediated or confounded.

All are simple. All can be said in one sentence. Yet all are incredibly profound and terribly underappreciated in today’s society.

I’m not going to go further than this, at least not today. The article is worth reading if this is a subject that interests you.

Shared cM Project

Shared cM Project

One of these days I need to take some time to write about calculating relationships between two people based on the amount of DNA they share. It seems like such a simple thing, but nothing is simple if no one has ever explained it to you. I run into a lot of people who just don’t get it, so they’re chasing down theories that make no sense.

In the meantime, here’s a quick intro from Your DNA Guide. Chart. Video. What more could you ask?

The way they explain it, “Blaine Bettinger at thegeneticgenealogist.com spearheaded the effort that became the Shared cM Project. He collected the shared cM data for known relationships from genetic genealogists just like you. This free tool gives you a good estimate of how much DNA should be shared for the different relationships.”

Maybe I can add that “cM” stands for centimorgan. A centimorgan is a unit of measurement for the distance between chromosome positions. Don’t worry about understanding it. It’s just a measurement word like feet and inches.

Blaine’s current chart is at August 2017 Update to the Shared cM Project. I like to go to his site directly so I can be sure I’m getting updated information. He has a summary of his posts at The Shared cM Project.

I also like Jonny Perl’s Shared cM Project 3.0 tool. Put in the number of cMs you share with someone and this tool with calculate the likely relationships.

Population Replacement

Population Replacement

DNA research is exploding established history everywhere we look. When I was growing up, everyone assumed that modern humans moved into Europe from the Middle East, spread out, and stayed. So, for us, history was pretty much invasions where different peoples took over new land, and (probably) exterminated or enslaved everyone who lived there before.

It turns out it wasn’t like that.

“Ancient DNA studies published in the last five years have transformed what we know about the early peopling of Europe. The picture they paint is one in which successive waves of immigration wash over the continent, bringing in new people, new genes and new technologies.

“These studies helped confirm that Europe’s early hunter-gatherers – who arrived about 40,000 years ago – were largely replaced by farmers arriving from the Middle East about 8000 years ago. These farmers then saw an influx of pastoralists from the Eurasian steppe about 4500 years ago, meaning modern Europe was shaped by three major population turnover events.

“The latest study suggests things were even more complicated. About 14,500 years ago, when Europe was emerging from the last ice age, the hunter-gatherers who had endured the chilly conditions were largely replaced by a different population of hunter-gatherers.”

“As conditions improved, it was these southern hunter-gatherers who took advantage and migrated into central and northern Europe, he says – meaning there was a genetic discontinuity with the hunter-gatherer populations that had lived there earlier [emphasis added].”

I don’t think this is the last word. The picture is getting clearer but it still seems fuzzy to me. We’ll see.
