Larger brains required a longer childhood in order to grow to their full size and acquire education. Females stayed to raise the children, allowing the men to hunt for food for the family unit. Males needed to learn to cooperate with one another in order to hunt; eventually, standing erect allowed them to use their hands for weapons, making the hunt more efficient.
These evolutionary developments created the need to establish pair-bonds in order to continue the species. Morris observes, "In our species there is . . . a strong tendency to 'fall in love' - to develop a powerful bond with the object or our sexual attentions. This sexual imprinting process induces the all-important long-term mateship so vital to the prolonged parental demands" (Naked Ape 95). Buss reinforces the importance of love in mate selection: "Many scientists believe that love is a Western notion, invented just a few hundred years ago. Our findings show those scientists to be wrong. People the world over value mutual attraction and love" (12). Love, whether as the impetus for pair-bonding or the result of an arranged marriage, is the biological drive that works to keep the mates together in order to raise the children they produce. The fairly modern acceptance of divorce in many cultures is an acknowledgement that biology is not always a strong enough force.
Other characteristics that Buss discovered to be universally preferred are all traits that tend to support the prese
