However, it's a little difficult to do that in fruit flies. (Laughter) It's kind of like landing on Mars and looking out the window of your spaceship at all the little green men who are surrounding it and trying to figure out, "How do I find out if they have emotions or not?" What can we do?
Sin embargo, es un poco difícil hacer eso en las moscas de la fruta. (Risas) Es parecido a aterrizar en Marte y mirar por la ventana de su nave espacial a todos esos hombrecitos verdes que los rodean y tratan de dilucidar, "¿Cómo averiguo si tienen emociones o no?" ¿Qué podemos hacer?
