Ancient Poop Science: Inside the Archaeology of Paleofeces
The invention of the toilet accomplished many good things, but it did rob us of the chance at immortality - through our poop. Ancient humans have revealed some of their greatest secrets through paleofeces, the study of the waste they left behind.
In studying ancient humanity, there's no more powerful resource than preserved DNA... theoretically. While DNA has evolved to be the molecule of life, it's not built nearly as well to stick around after its organism is dead and gone. There are a few ways to preserve DNA for up to as much as a million years without complete degradation, but these mostly involve being frozen in ice or permafrost.
