Now, these aren't just differences in anatomy, like the shape of your ear lobes, but they have consequences in thought and behavior that are well illustrated in this famous cartoon by Charles Addams: "Separated at birth, the Mallifert twins meet accidentally." As you can see, there are two inventors with identical contraptions in their lap, meeting in the waiting room of a patent attorney.
No sólo son diferencias anatómicas, como la forma de las orejas, sino que hay efectos en el pensamiento y la conducta que ilustra claramente esta caricatura de Charles Addams "Los gemelos Mallifert, separados al nacer, se encuentran accidentalmente." Como ven, son dos inventores con artilugios idénticos en la falda y se encuentran en la sala de un abogado de patentes.
