"Great journey" is how British archaeologist Brian M. Fagan described the early migration of homo sapiens some 200,000 years ago from Africa to the rest of the world and their progression to become a dominant species.

In 1993, Japanese traveler Yoshiharu Sekino decided to backtrack the migration route on foot — starting from the Chilean island of Navarino and working his way to East Africa. This exhibition reveals the lives of people who now inhabit the less-traveled and unprosperous areas of Sekino's journey. Using examples of mummies, a shrunken head and other artifacts, the exhibition illustrates the tale of human development; till June 9.
