Have you read this article on ancient tooth bacteria?

Ancient Teeth Bacteria Record Disease Evolution raises some interesting questions.

Here's a quote.

"Oral bacteria in modern man are markedly less diverse than historic populations and this is thought to contribute to chronic oral and other disease in post-industrial lifestyles."

It mentions bacteria from 7500 years ago, so this is at the start of grain consumption, but perhaps there's enough DNA there to identify species of bacteria that we lack today. IMHO, the bacteria itself was driven by the diet, specifically macro ratios, so a transplant of ancient tooth bacteria might not be useful.

But, might it be useful for paleo eaters? And would an analysis of paleo eaters match species from ancient teeth?

I suspect a lot of those bugs still exist today and switching to low carb paleo selects for them if we're exposed to them, or at least their modern versions. I don't think we're that far off, which is why I asked the question. Of course, I don't have any way to test such a supposition, but just imagine if the results came back and the guys doing this sequencing also tested some of us and found the same bugs!

Um, this was from fossilized tartar/dental plaque, not coprolites. Sorry.

Useful? You bet! I want a fecal transplant from 7,500 years old. That will fix my evil bacteria.

Thanks for the link.

Couple of thoughts:

1) Law of unintended consequences -- I've seen Jurassic Park, bringing back extinct things doesn't always work out too well....

2) Those bacteria are not necessarily agile enough for modern diseases, so they could be ineffective. Try some old school weed killers on GMO corn...
