The sociobiologists have shown that women’s and men’s different “shopping styles” are rooted in our distant evolutionary past. Man-the-hunter wants to shop for specific items, quickly, and then drag his kill home. Woman-the-gatherer, by contrast, spends hours “trying to find the right outfit, present or object, because [she] had in the past spent ages trying to find the best quality and health giving foods.” The study’s lead author, Daniel Kruger, hopes that understanding each other’s shopping strategies will help men and women to avoid arguments during the Christmas rush. Helpful research, indeed! Unfortunately, there’s no word yet on how our Stone Age ancestors managed to find a good parking spot at the mall.
