NatGeo: UC discoveries featured in new series on ancient Maya
National Geographic's new series “The Rise and Fall of the Maya” features discoveries made in Tikal and other sites by researchers at the University of Cincinnati.
In the series' third episode titled “Collapse,” UC College of Arts and Sciences Professor David Lentz discusses their findings about ancient Maya water filtration in the city.
The ancient Maya in Central America were known for ingenious engineering, sophisticated writing and astronomy.
“All of these things are hallmarks of a great society,” Lentz said.
A team of UC researchers has been applying new scientific techniques to unlock the secrets of the ancient civilization. They discovered sophisticated water filtration systems that used a mineral called zeolite to provide clean drinking water. Paradoxically, some reservoirs in the city center also contained toxic levels of mercury and cyanobacteria.
More recently, UC has been using the latest molecular tools to examine environmental DNA from archaeological sites at Tikal and other ancient Mayan cities.
Lentz, an archaeobotanist in UC's Department of Biology, has been working with longtime collaborators, including UC Professors Emeritus Vernon Scarborough and Nicholas Dunning and UC College of Medicine Professor Emerita Alison Weiss.
Researchers spoke to Lentz at the ancient city of Calakmul in Mexico. The National Geographic episode documented the team's analysis of samples taken from Tikal in a biology lab back on UC's campus.
“This is the exciting moment. We get to see if all of that work has resulted in DNA in our samples. I have high hopes,” Lentz says on the show as botanist and UC Associate Professor Eric Tepe brings up the results on a machine.
“The remarkable thing is that in these two microliters we measured, there can be DNA from hundreds and hundreds of plant species,” Tepe told National Geographic.
