This is not virology, but it is nonetheless fascinating. Archaeologists have found fossilized human feces in a cave in Oregon. The fossils, called coprolites, are just over 14,000 years old. In addition, DNA analysis indicates that they contain human DNA, and furthermore indicate origins from Siberia and East Asia. This discovery is consistent with the hypothesis that humans arrived in North America over a land bridge between Siberia and Alaska.
