While the western Roman empire was falling in Europe, in the Americas one of the most spectacular civilizations was reaching its peak. With advanced astronomical capabilities, a precise calendar system, massive pyramids, and millions of people, the Mayans had no equals in their day. A few hundred years later, the classic Mayan cities emptied, and their written inscriptions ceased. In short order, their enormous temples were swallowed by the jungle and remained hidden under dense foliage for almost a thousand years. Then, in the early 1800s, the mysterious classic Mayan civilization was re-discovered. Why did it disappear?

For decades, mainstream scholars have debated this question without resolution. Now, with new genetic discoveries in hand, this long-standing mystery might finally be resolved. Tune in to find out what happened to the Maya!
