In the 1960s, a group of researchers conducted a study by placing sweet potatoes on a sandy beach to draw the Japanese macaques, a type of monkey, out of a nearby forest. After some time, the macaques started coming out on the beach and brushing the sand from the sweet potatoes before eating them. A year later, the researchers observed a female macaque washing a sweet potato in the ocean before eating it, and all other macaques in the troop copied her behavior. When these macaques gave birth, the offspring were also observed to perform the same behavior. What can be concluded from this experiment?

The offspring inherited the characteristic of washing the sweet potato before eating from their parents.
