Researchers were able to confirm that early Americans not only had dogs, but also, that they ate them. How they found this out is fairly straightforward and just about what you would expect....LOL. Yes, they were digging around in a gigantic pile of poo. But even more shockingly, what they found in the poo was stored at Texas A&M University for over 35 years, and just now got examined and tested in detail. I can just imagine everyone standing around going, 'Why don't you check out what we found at the bottom of the gigantic pile of poo?' and the other guys saying, 'I don't wanna do it, YOU do it', for the last 35 years. But the news article also said that there was evidence of dogs existing far longer ago than that in Europe - 24,000-30,000 years in various locations in Europe. I'm not sure that they have proven exactly HOW domesticated they were. They didn't find any fossilized rain booties or dishes marked, 'Precious'.
