23andMe’s Historical Matches

[JMcB]

Apparently, 23&me has launched a new feature (for their premium customers).


23andMe’s Historical Matches

Are you distantly related to the legendary, like the great musical genius Ludwig Van Beethoven? Perhaps you are genetically related to a high-status Viking woman from the 9th century who was buried in an ornate coffin with ornaments made of copper and a comb made from antlers? Maybe you’re linked to an African female Hunter-Gatherer buried with her bow and arrow and an ivory armband or a Caquetio man found with shards of decorated pottery at a site in Curaçao that dates back to before the first colonizers arrived in the Americas.

Woven into our DNA is a history thread linking us to our relatives, their stories, and the broader human story.


Historical Matches

This week, 23andMe launches its first iteration of “Historical Matches.” This powerful and unprecedented new 23andMe+ Premium feature may connect you to one or more of 335 historical people across the globe. The technology works by identifying places in your genome where you share identical DNA inherited from a shared ancestor. This might be someone who lived long before you or your historical match. This creates a new way to learn more about your connections to the past.

Over time, 23andMe plans to add more historical genomes to the feature, offering customers more opportunities to connect their stories to past epochs.

“23andMe’s Historical Matches is a technical breakthrough in our ability to accurately detect genetic connections between customers and historical individuals,” said Dan Chu, 23andMe’s Chief Product Officer. “It uses cutting-edge science to provide customers with connections to history that can be fun, and in some cases, deeply personal and profound.”

23andMe is the first leading DNA ancestry service to offer this level of genetic matching to relatives of historical peoples based on peer-reviewed published methods and deep data analysis.

European customers can't have it right ?

Do they show the matching chromosome segment as well ?

If they want more European customers, they should offer them something of value again.

They say I have 10 without paying for the Premium. I wonder what they are.

May I ask where you found that? I couldn’t find that on my account. Although, it probably doesn’t matter because I’m not paying anything to see what they’ve found.

[Riverman]

@JMcB, Sure it's under account overview. It's a V5 chip account. Maybe that's why. I'm not paying either.

I'm V5 and get nothing. Probably I'm not processed for the new feature yet, probably its because I'm no premium user, or, alternatively, I don't have any ancient DNA matches in their current data base.

Thanks, now I got it! I have 8 historical matches.

23andMe must still be angry at me for having my account hacked.  LOL. I don't even see any reference to this feature on my account. Granted, I do have v3. FTDNA has something very similiar with its BigY feature. Of course the matches there are though my Y-dna there. Are these matches autosmal matches?

Yes, they are. Judging from what I’ve seen on Facebook, they’re naturally of a very small order (4 - 6.7 cMs). It reminds me of what we use to do on Gedmatch, where you could compare you DNA to their ancient sample list by lowering your threshold to a similar range of cMs.

one question , how is possible match with something so old? for example a match with ancient sample , what probability to be true?

Through y-DNA or mtDNA you can go back about as far as possible, especially y-DNA. Autosomal DNA might go back 7 generations, at most. That's why asked if they were doing any autosomal matches, altghough I wouldn't call that "ancient."

but how works this matches for example with viking samples that 23andme have? matchs is only with Y and mtdna?

That's what I was asking earlier to be certain. I would have to say, yes. That would be the only way to claim a match with a sample that is that old. Re; 23andMe, I can't say, since I have posted that they are not offering me the opportunity to view the matches, even though I have an account there. At FTDNA, this is what it looks like:

I would be interested to know if anyone can track these historical matches back through a parent who has also tested.

Preferably, looking at both parents.

Usually, Famous Matches or Famous Ancestors etc fall into the Infotainment bucket.

Only autosomal:

While previous ancestry features allowed customers to find out if they were genetically connected via their maternal or paternal lines, this new feature searches across the whole genome to connect members to historical individuals who lived hundreds or sometimes thousands of years ago by finding identical segments of DNA in their genomes.

Like 23andMe’s DNA Relatives feature, Historical Matches searches for shared segments of DNA between 23andMe+ Premium members and historical individuals. The feature identifies matches by finding segments and looking at the length of DNA that subscribers share with these historical individuals. Creating quality thresholds for how long a shared segment must be for a match makes it unlikely that there would be “false positive” matches.

It is entirely possible, and even probable, that small segments of 5 centimorgan or less are preserved for centuries.
On the other hand, phasing with a parent is necessary for the segment to be valid. It is not with their threshold criterion that will make them credible in my opinion.
