The concept of the “man cave” has been entrenched in the human lineage for far longer than thought, according to new research that analyzed teeth from early humans to determine their geographic movement.
Scientists from the University of Colorado at Boulder found that males of two hominid species that roamed the South African savanna more than a million years ago stayed close to home—which often included caves—while females tended to move away.
The study, published in the June 2 issue of the journal Nature, suggests that fossils can reveal clues to early humans’ social and gender-related behavior, said Jeffrey Laitman, director of the Center for Anatomy and Functional Morphology at the Mount Sinai School of Medicine in New York City.
“This is strong and beautiful science,” Laitman said. “It at least is giving us a glimpse that some of the behaviors we see today have roots going into the past. It may well be in our lineage that [males] liked their man caves.”
