Did you know that you can distinguish between an American and people form other countries based on their carbon isotope content? I kid you not!
Thanks for linking to this interesting article. I already went through PNAS table of contents today and I do admit that this totally escaped my attention!
Well, that's good news for forensic anthropologists of the future!
And don't worry, this paper was under the environmental sciences heading. I know for a fact that I miss all the juicy stuff under biochemistry ;)
