Only in the past 25 years have scientists learned of the strange lifestyle of African mole-rats. All 12 species live entirely underground. A few colonies of naked mole-rats, a social species of the family, have been raised for study purposes in a specially designed observation tunnels.

Were it human, the family would argue it out on a national talk show. As it is, the social behavior of these tiny rodents has scientists intrigued, right down to their naked mole-rat molecules. "African mole-rats are very good models for studying social structure. I'm interested in the genetic markers associated with structure," said Colleen Ingram, whose doctoral degree will be bestowed Friday at Texas A&M University based on her findings about the critters' parentage.
