 Correspondent Donna Warner reports on termite mounds in South Africa. Scientists say they're more than 30,000 years old. Researchers at Stellenbosch University say the 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 Namakwa land. Senior lecturer Michelle Francis says the mounds existed while saber-toothed cats and woolly mammoths roamed other parts of the earth.
