By exploring the nature and evolution of macaque social organization, we can develop our knowledge of the rise of societies and their transformation during the course of evolution.Professor Darío MaestripieriUniversity of Chicago HUMAN ≡ RHESUS MACAQUE Comparative Human In the struggle for survival, both resorted to the same solution: Development SOCIAL INTELLIGENCE Evolutionary Biology Neurobiology

Represent others people’s Share the feelings of others intentions and beliefs (in the absence of any direct emotional stimulation to themselves) Mentalizing (ToM) Emphaty These concepts refer to our ability to put ourselves in the shoes of another person, be it in their mental or emotional shoes. > Allow human beings to represent the states of other people (mental or emotional) > Predict others’ behavior Successfully engage in social interactions.* T. Singer. There is neurological evidence for these division.
