How do regulatory networks evolve and expand throughout evolution?

How do media expand?

We conducted an in-depth, micro-level process analysis of 36 experimental groups working on a decision-making task in either desktop videoconferencing, audio conferencing or face-to-face environments. Using the framework of Giddens’ structuration theory, we observed social structures producing behaviors and social structures reproducing behaviors that participants exhibited during the experimen...

How ecological networks evolve

Ecological networks represent the backbone of biodiversity. As species diversify over macro-evolutionary time-scales, the structure of these networks changes; this happens because species are gained and lost, and therefore add or remove interactions in their communities. The mechanisms underlying such dynamic changes in ecological network structure, however, remain poorly understood. Here we sh...

How do dynamic heterogeneities evolve in time?

We present simulations of a hard disc system and analyze the time evolution of the dynamic heterogeneities. We characterize the time evolution of slow regions and slow particles individually. The motion of slow clusters turns out to be very restricted, i.e. a cluster is generated and annihilated in a spatial region four times the size of its maximum extent. The residual motion of the cluster ca...

Complex systems: Why do they need to evolve and how can evolution be supported

We live in a world characterized by evolution—that is, by ongoing processes of development, formation, and growth in both natural and human-created systems. Biology tells us that complex, natural systems are not created all at once but must instead evolve over time. We are becoming increasingly aware that evolutionary processes are ubiquitous and critical for social, educational, and technologi...
