Famous Dutch primatologist Frans de Waal dies aged 75. He is the one who showed emotions and consciousness in animals.
De Waal showed that animals have emotional intelligence. And not just primates or pets. For him, cows, pigs or chickens also have sensitive experiences. For the Dutch, laughter is not unique to man either. “If we tickle a chimpanzee, it makes a face and makes noises like when we laugh ” he explained in 2018 on French television.
