Y DNA Tree of Mankind Reaches 50,000 Branches

At this time is a extremely, REALLY massive day within the genetic family tree world.

The Y DNA tree of mankind at FamilyTreeDNA has reached 50,000 branches. That’s fairly a milestone!

There’s been remarkably fast progress prior to now three years, as proven under.

From the FamilyTreeDNA blog article announcing this milestone event, we see the expansion from 2018 to current cumulatively and inside every haplogroup. In fact, haplogroup R, current in very excessive frequencies in Europe, kinds the bottom of this mountain, however each haplogroup has achieved vital good points – which advantages all testers.

Who’s Department 50,000?

Michael Sager, the phylogeneticist at FamilyTreeDNA simply added department 50,000.

Drum roll please! Who’s it? Surprisingly, it’s NOT present in haplogroup R, however a person from Vanuatu, a rustic in Oceania.

The brand new department is a member of haplogroup S – particularly S-FTC416, instantly downstream of S-P315. Haplogroup S is present in Indonesia, Micronesia and different Pacific Island nations, together with Australia and New Zealand.

This man was a brand new buyer who joins a few Aboriginal samples present in educational papers from Kuranda (Queensland, Australia) and three historical samples from Vanuatu.

How cool is that!!!

We’ve Come a LONG Manner!

The Y DNA phylogenetic tree has been rising like wildfire.

  • Again in 2002, there have been 153 branches on the Y-DNA tree, and a complete of 243 identified SNPs. (Some SNPs had been both duplicates or not but positioned on the tree which explains the distinction.)
  • In 2008, six years later, the tree had doubled to 311 branches and 600 SNPs. On the FamilyTreeDNA Worldwide Convention that 12 months, attendees obtained this poster. I keep in mind the mission directors marveling about how massive the tree had grown.
  • In 2010, two years later, the tree was comprised of 440 branches and 800 SNPs. That poster was even larger, and it was the final 12 months that the phylotree would match onto a poster.
  • By 2012, when the Genographic Project V2 was announced, that bombshell announcement included information that the Genographic mission was testing for 12,000 SNP places on their chip, not all of which had been labeled.
  • In 2014, when FamilyTreeDNA and Genographic jointly released their new Y tree to rejoice DNA Day, the Y tree had grown to greater than 6200 SNPS, of which, greater than 1200 had been end-of-branch terminal SNPs. If this had been a poster, it could have been greater than 62 toes lengthy.

From that time on, the trajectory was unstoppable.

The earliest SNP-seeking product referred to as Stroll the Y had been launched adopted by the first-generation highly effective Large Y NGS DNA scanning product.

That’s 1300% progress, or mentioned one other manner, the database elevated by 13 instances in 4 years.

Within the three years since, a lot of these SNPs, plus personal variants that had not but been named at that time have been added to the tree.

In January 2019, the Big Y-700 was announced and many individuals upgraded. The Big Y-700 supplied dramatically elevated decision, which means that check might discover extra mutations or SNPs. The impact of this granularity is that the Big Y-700 is discovering mutations and new SNPs in a genealogical timeframe, the place the unique haplogroups a number of years in the past might solely piece collectively deeper ancestry.

The Big Y-700 has made a HUGE distinction for genealogists.

  • At this time, in December of 2021, the tree hit 50,000 branches. That poster can be greater than 500 toes lengthy, virtually twice the size of a soccer discipline.

I’ve to marvel what number of extra branches are on the market simply ready to be discovered? What number of will we discover within the subsequent 12 months? Or the subsequent?

The tempo doesn’t present any indicators of slowing down, that’s for certain. Including educational and historical samples to the tree helps an excellent deal by way of including context to our data.

What gems does your loved ones’s Y DNA maintain?

How Does a SNP or Variant Get Added to the Tree?

You could be questioning how all of this occurs.

A SNP, which turns into a haplogroup has three states of “being,” following discovery.

  1. When the mutation, termed a SNP (single nucleotide polymorphism), pronounced “snip” is discovered within the first male, it’s merely referred to as a variant. In different phrases, it varies from the nucleotide that’s usually present in that place in that one man.
  2. When the SNP is present in a number of males, assuming it’s discovered persistently in a number of scans, and it’s in an space that’s “clear” and never genetically “noisy,” then the SNP is given a reputation like R-ZS3700 or R-BY154784, and the SNP is positioned on the tree in its right place. From my article last week about using Y DNA STR and SNP markers for genealogy, you’ll be able to see that each of these haplogroups have a number of males who’ve been discovered with these mutations.
  3. Some SNPs are equal SNPs. For instance, within the picture under, the SNP FT702 as we speak is equal to R-ZS3700, which means it’s present in the identical males that carry R-ZS3700. Finally, many equal SNPs type a separate tree department.

In the future, some man could check that does have R-ZS3700 however does NOT have FT702, which implies that a brand new department can be shaped.

When males examined that had R-BY154784, that new department was added to the left of R-ZS3700, as a result of not all males with R-ZS3700 have the mutation R-BY154784.

You’ll discover that the teal blocks point out the variety of personal variants that are mutations that haven’t but been present in different males on this identical department construction, and people variants are due to this fact not but named SNPs.

If You’ve Already Examined, How Do You Obtain a New Haplogroup?

It’s value noting right here that not one of the terminal SNPs that outline these branches had been accessible utilizing the older Large Y checks which illustrates clearly why it’s necessary to improve from the Large Y or Large Y-500 to the Big Y-700.

In my Estes line, the terminal SNP within the Large Y-500 was R-BY490. These identical males upgraded to the Big Y-700 and have now been assigned to 4 completely different, distinct, genealogically vital lineages primarily based on SNPs found after they upgraded. Some males have three new SNPs that weren’t accessible in earlier checks. In actual phrases, that’s the distinction between the frequent ancestor born in 1495 and descendants of John R. Estes who died within the Eighteen Eighties. Genealogically talking, that’s night time and day.

If you happen to haven’t taken a Big Y test, I heartily advocate it – even when you don’t have STR matches. I talked about why, here. Males can purchase the Big Y initially, or sign on to your account and upgrade when you’ve already taken one other check.

In a nutshell, the Big Y-700 test supplies testers with two varieties of instruments that work each collectively and individually to offer genealogically related data.

To not point out – you could be chargeable for rising the tree of mankind, one department at a time. What’s waiting for you?
