Explanation:
Silk, tea and spices weren't the only things that travelers carried on China's legendary Silk Road: Ancient poop shows that infectious diseases were also transported along this network of trade routes, according to a new study.
Researchers excavated 2,000-year-old feces from a latrine along the Silk Road in northwestern China, and found that it contained eggs from the Chinese liver fluke, a parasitic worm that is typically found at least 930 miles (1,500 kilometers) away, according to the study.
The researchers suggested that the traveler infected with this parasite must have journeyed a great distance. "This is the earliest evidence for the spread of infectious diseases along the Silk Road, and the first to find evidence at an archaeological site along the Silk Road itself," Piers Mitchell, a paleopathologist at the University of Cambridge and the senior author of the study, told Live Science.

The researchers found the feces on "personal hygiene sticks" — wood or bamboo rods with cloth wrapped around one end that people used to wipe excrement off bottoms. Under a microscope, the researchers examined the feces from seven of such sticks to look for signs of ancient parasites.
The third theory, supported by Ross Hassig (1992), states that the decline of Teotihuacan was caused by the deterioration of economic conditions. The last theory was devised by George C. Vaillant (1950) and argues that Teotihuacan dissolved because of an internal revolt against the elites controlling the city.
