Marc D. Hauser
A slender loris comes up to a zoo keeper and hugs him. A dog lowers its head and whines when its master is unhappy. Is such behaviour a sign of affection and empathy or are other mechanisms at work, to explain the animals near-human behaviour? Why do chimps and dolphins form coalitions to defend themselves? How do lions determine, from far away, the number of gazelles calmly watering by a stream? How is it that a few species can recognise their own image in a mirror? Marc D. Hauser is a professor of psychology and neuroscience at Harvard University, where he is a fellow of the Mind, Brain and Behavior Program. Besides performing laboratory research, he has done extensive fieldwork in Kenya, Uganda and Puerto Rico.
