Poop Shows Ancient Human Gut Microbiomes Resemble Modern Non-Human Primates More Than Us

If you are an organic food or paleo diet lover and think it means your gut microbiome resembles your ancestors in any way, you are wrong. We aren't even close to 100 years ago much less ancient times. The microbiome does not lie.

A team analyzed microbiome data from ancient human fecal samples collected from three different archaeological sites in the Americas, each dating to over 1000 years ago. They also did a new analysis of published data from two samples that reflect rare and extraordinary preservation: Otzi the Iceman and a soldier frozen for 93 years on a glacier.

"The results support the hypothesis that ancient human gut microbiomes are more similar to those of non-human primates and rural non-western communities than to those of people living a modern lifestyle in the United States," says Cecil M. Lewis Jr., professor of anthropologyat the University of Oklahoma. "From these data, the team concluded that the last 100 years has been a time of major change to the human gut microbiome in cosmopolitan areas."
