Meanwhile, prehistoric women, who gathered more-sedentary food, probably found their way to and from the most bountiful and nutritious plants with the help of landmarks. In a study last year at the University of California at Santa Barbara, evolutionary psychologist Joshua New tested this theory in a farmers' market. After a single tasting tour of the market, women could more accurately point to food stalls they had visited, noting, in particular, the locations of foods with high energy content. With the benefit of food stalls as landmarks, women knew their way around better than men.
