Archaeologists have discovered human droppings in a cave in North America that date thousands of years earlier than original evidence of a human presence in North America.
Originally the Clovis period was thought to be the earliest time that humans inhabited North America. But a recent discovering in a North American cave have thrown this theory into the toilet.
Humans may have just dropped by this cave 14,000 years ago to take a dump or maybe they lived there for many years and used the place as their toilet of choice.
Either way scientists agree that the most reliable remnant of a true human presence is the shit that they leave behind.
