Primate study offers insights into relationship between of jealousy and monogamy
Washington (UPI) Oct 19, 2017
The origins of jealousy and the evolutionary significance of the emotion are difficult to parse, especially in humans. But new analysis of jealousy among primates has offered scientists fresh insights into the neurobiology behind the powerful emotion. The latest research suggests the emotion triggers an increase in neural activity among parts of the primate brain associated with social pain. But it also excites parts of the brain associated with social bonding. "Understanding the neurobi ... read more
