Dr Christina Warriner, Science Of Human History, Max Planck Institute discussed on Quirks and Quarks
And then we use this to try to project into the past now. When we apply this sort of program to fresh fees, it's actually has extremely high accuracy, and we can segregate very well the problem. Problem really comes when you're applying this the Paleo feces, because we face all of the challenges of archaeological material, the DNA is damaged it sure it contains airs due to the degradation process, and has some soil bacteria mixed in that have come in from the environment, and so what we try to do with this approach is take all of those factors into account and make an assessment on the likely origin. Well now that you know that so many of the feces you were working on came from dogs, and not humans What can you still learn from that? I think one thing that's quite exciting. As we now potentially have new source of genomic information for dogs, fortunately, though a lot of the Paleo feces we are looking at is human, and so we're carrying forward with the research we started with, but now we can be much more confident that when we are reconstructing the history of the human, Gut microbiome we truly are focusing on humans. I'm just trying to imagine the excitement in an archaeological dig when somebody says hey I found deterred. You know, archaeologists are a strange breed, and we tend to get very excited about these sorts of things, so I know that for the average person, it might seem a little bit strange, but latrines and trash pits are some of the most interesting things that in archaeologists connects kate. Warner thank you very much for your time. Thank you so much.
