Ecology and evolution are inseparable. Motivated by some recent experiments, we have developed models of evolutionary ecology from the perspective of dynamic networks. In these models, in addition to the intra-node dynamics, which corresponds to an individual-based population dynamics of...

The standard neoclassical approach to economic theorising excludes, by definition, economic emergence and the related phenomenon of entrepreneurship. We explore how the most economic of human behaviours, entrepreneurship, came to be largely excluded from mainstream economic theory. In contrast,...

We introduce a network formation model based on the idea that individuals engage in production (or decide to participate in an action) depending on the similar actions of the people they observe in a society. We differentiate from the classical models of participation by letting individuals to...

We propose a generic model of eco-systems, with a hierarchical food web structure. In our computer simulations, we let the eco-system evolve continuously for so long that we can monitor extinctions as well as speciations over geological time scales. Speciation leads not only to horizontal...
