Upcoming paper on Anglo-Saxon migration period??

I'm intrigued by the PCA in the Hines lecture, visible in the bottom left corner from around 41:00 to 44:00.

I don't think I've ever seen it published in a study before and I wonder if it's from the new one. Anyhow, the quality obviously isn't great but you can see that they've labelled a number of ancient samples as well as modern ones and defined a "British/Iron Age Cluster" and an "Anglo-Saxon cluster." I'm assuming that the shapes (dots vs triangles) are in relation to what period they come from, with the former being IA and the latter AS.

Very nice spot Cartographer! I see the lecture took place on November 12, 2020. I thought it might have been Hinxton data for a second but doesn't look like it, at least to me.

There is more from Hines. For example, these lectures appear to be more archeologically focused.

If you want to get smarter on radiocarbon dating and calibration, start watching at the 36 min mark.

You can tell he's a good lecturer. Ends his lecture right at the 1 hour mark

Didn't realize sunspot activity impacted the amount of carbon-14 in the atmosphere. That was interesting. So testing results prior to 1980 need taken with a grain of salt as far as accuracy.

Seafood intake swings the numbers making them look 300-400 years older. High precision can get within +/- 13 years. Curious how they can determine sunspot activity hundreds and thousands of years ago in order to calibrate?

Really interesting stuff, thanks Mitchell.

At the 1:21 mark he talks about this "Dust Veil" event of 536 AD. I was unfamiliar with this event

I've got it tagged in YT to watch later. Looked like an informative presentation. Good find.

I mentioned this at #22 and it's a big event for the Migration Period Mitch. I hope your Y DNA search takes a new turn because you'd find much to enjoy in this field. It's as interesting as the endlessly fascinating IA Celtic stuff for sure.I can see you're getting hooked.

I just went back and looked at post #22. Phew! Thank goodness I hadn't previously "liked" your post...that would have been embarrassing.

Does anybody have any thoughts what the PC1 and PC2 axis represent?

It appears a line runs from Irish at the top right to Netherlands at the bottom middle. I'm guessing this a something akin to a Celtic vs Germanic line.
Another line appears to denote Nordic at the upper left and again Germanic at the bottom.

To me it looks as though [pre]Migration era Jutlanders (Angles and Saxons*) may more closely resemble Frisians and West Germans than modern drifted Scandinavians; although both are on the germanic side.

*Or their Angles and Saxon samples have already mixed in with Britons, Frisians and West Germans.
