NEW EVIDENCE FOR MAYAN COLLAPSE

New-found evidence of the worst drought in the past 7,000 years may help explain the unexplained collapse of the Mayan civilization. Samples of ancient mud from the bottom of a lake in the area where the Mayans lived show signs of the severe drought right around the time the Mayans mysteriously abandoned their cities. Anthropologists believe the new evidence fits the generally accepted theory that a number of factors -- drought, overpopulation, inter-city warfare and environmental collapse -- brought on the society's demise.
