 Correspondent Donna Warder reports on termite mounds in South Africa that scientists say are more than 30,000 years old. Researchers at Stellenbosch University say through radiocarbon dating, they found some of the mounds to be 34,000 years old, and they're still inhabited. They're near the Buffaloes River in Namaqua land. Senior lecturer Michelle Francis says the mounds existed while saber-toothed cats and woolly mammoths roamed other parts of the earth.
