The Book of Invasions (written in the 11th century) says the Partholonians, the second group to settle in Ireland, died from a pestilence. You can’t help but wonder if a plague/pandemic (a real one)

Nigel, I believe you include STR mutations in those calculations? Hence a smaller rate than for SNPs only. E Sent: 07 September 2021 07:15 To: [email protected] Subject: Re:

In answer to this specific question I am estimating the A212 Block comprising 3 SNPs and 3 STR mutations occurred between 100 and 325 A.D. after which two Robertson kits without the 18 to 19 mutation

I think Iain’s methodologies are trying to incorporate local recalibration of mutation rates using known pedigrees and the radiocarbon dated samples. Unfortunately, I just haven’t had time to

Thanks, James. John, did you have any luck clarifying point 1? Re second point, have the genetic genealogy number crunchers considered trying to adjust their average SNP mutation rates to coincide

1) I don’t have the raw data for the ancient sample. I someone has the ENA identifier for the data, I can go retrieve it. 2) We can’t really draw conclusions at this time. Radio carbon dating is

I see two issues here – 1. I don’t know that we know if the FGC11134 ancient DNA was tested far, if at all, beyond FGC11134 itself. James, you were looking at what raw data you had access to –

Hi, I didn't say I necessarily agreed with it at all, I'm agnostic on the point. Following the evidence, what you suggest is reasonable N ________________________________ Sent: Monday 6 September 2021

Neil, A potential contributor to a SNP bottleneck might be the phenomenon known as the 'Late Iron Age Lull'? Discussed briefly (since it antedates his main focus) by Dr Matthew Stout in his 2017 book

What does this new?TMRCA mean for?Nigel McCarthy's PHYLOGENETIC ALIGNMENTS WITH GENEALOGIES OF DESCENT FROM AILILL?LOM ? Especially interested about A212.

*If CTS4466 TMRCA is 250CE then IMO it clearly increases the likelyhood of it being of Irish rather than Welsh origin.* I will point out (again) that FGC11134 (parent of CTS4466) remains were carbon

On final point, if the archaeological evidence doesn’t point to an Iron Age invasion, or if the linguistic evidence doesn’t point to any significant interruption or linguistic revolution in

On another point, if CTS4466, particularly R-A541, Irish Type II, is the dominant snip marker in the Southwest of Ireland, 250AD might seem a little recent to establish a founder effect. The other

James, I took ‘TMRCA: 1050BC [ 2150BC - 0AD 95% confidence using 155 NGS samples ]’ from your http://it2kane.org/matrix/R-FGC11134.html . E Sent: 06 September 2021 17:16 To:

If we’re agreed that CTS4466 probably didn’t form on the island of Ireland, but in Wales – or perhaps further afield, 250AD would be a significant date. It would mean that the arrival of the

I think it probably varies in every line how quickly snips form, or don’t. After a lot of persuasion I managed to arm twist my closest phylogenetic relative to test with me, to branch out our tree.

The thing about the age estimates is that you only count SNPs that fall inside the regions where there has been work to study the rates of mutations. While there are 20 equivalent SNPs only 15 are

Which browser specifically are you using? I only test with Firefox and Webkit regularly. Depending on when you were trying, there was a brief period where the server was running at 100%. It might have

To all: This time/SNP thing intrigues me greatly (as I assume it does others). Let’s do a little kindergarden math: Elizabeth notes that James has CTS4466 formed 3,000 ybp and its’ TMRCA at 1,700
