you know that oxygen isotope values change throughout history? The reference map is a recent snapshot..
-
Not according to Evans et al 2012....

(in Journal of Analytical Atomic Spectrometry, 27 (2012), 754–64 at p. 758)

thx, didnt know that one, but still I think we should be critical at the isotope data as they cannot pinpoint exact locations
-
Concur on that, esp as European δ¹⁸O range v similar to GB; however, focus here on those well above European range
-
δ¹⁸Op results of 14-18‰ common across Europe, so individual w/ such a value v hard to pin down, but those in post=19.2‰ to 21.3‰

But... what does oxygen isotopes in spring water have to do with supposed african migrants?

Record of isotope value of water drunk in childhood preserved in teeth: v high values not found in Europe etc.pic.twitter.com/NVvc2o2vgH

Even though you yourself say that it's likely those high results were due to pre-selection of sites
-
High isotope results are real; overall *proportion* of high results *might* be due to 'interesting' sites being >

i apologise for that person in your mentions, Dr Green.
