Traveling on Foot

Caption

A tribal member in Namibia surveys the landscape. A new University of Utah study of Namibia's Twe and Tjimba tribes found new evidence that men with better spatial ability -- the ability to mentally manipulate objects -- roam farther than other men and have offspring with more women. The study sought to explain why men evolved better navigation skills than women.
