Societies today face daunting challenges: population growth, rapid urbanization, ecological and environmental disturbances, and an unpredictable global marketplace. To address these complex and ...

We are building a theoretical framework that will guide the creation of artificial agents that adjust their neural networks (brains) to feedback from their bodies and surroundings -- in essence to ...

Polygyny is thought to be more prevalent where male wealth inequality is greater; however, the decline of polygyny in most of the world occurred with the emergence of capital-intensive farming with ...
