Hope is our strength......love is our determinatio
I appreciate the many useful links you've provided in this thread. You're referring to this, I think?
I hope it's all right if I clarify:
The paper you linked refers to hydrogen isotopes. (2)H is an abbreviation for deuterium, an isotope of hydrogen sometimes called "heavy hydrogen."
The paper says that (2)H in hair, fingernails, and bone collagen and (18)O (an oxygen isotope) in bones and tooth enamel can be used to investigate geographic origin and migration, but that (2)H in tooth enamel appears not to be useful because the values are fairly stable over different geographical regions. In other words, isotope analysis for adolescence is not discredited as a whole, but according to these researchers you probably don't want to use (2)H1)H from tooth enamel for it.
The information we have on Cali Doe's possible origin from her teeth came from oxygen isotope analysis, probably (18)O16)O.
Anyway, that was just a side line of thought and probably not a very useful one.Better to lean more on the data itself rather than on hand-wavey interpretations of the data.
Oh very nice!!!! Thank you. Your clarification certainly makes the isotope information easier to understand. As for the starches, that I would guess would probably be more of a economic than a regional factor. (only a guess) Many families with limited income make their own breads rather than buying things pre-baked. Yes, Flour was equally affordable and by that time period was being used just as often. So it was another thing that was a matter of personal preference. I can understand why the data would be interrupted to believe the high corn diet was more likely an indicator or certain regions.
