Figure 2 Reliving the past. Four Massachusetts Institute of Technology undergraduates and their archaeology professor Dorothy Hosler built this replica of an ancient Ecuadorian sailing vessel--but with plywood and Styrofoam instead of authentic balsa wood--and sailed up the Charles River earlier this month. Archaeological evidence suggests that Ecuadorian sailors brought metalworking to western Mexico over a millennium ago, but scientists don't know how they navigated the 4800-km journey. To find out, the students plan to retrace the voyage next summer in a larger replica.
