Howard Rheingold TED talk urges a global movement to study cooperation

Posted 21 Oct 2011 / 1

A few weeks ago I posted an aside about Howard Rheingold’s 6-week online course on cooperation theory. One of my questions about the course regarded how to assess Rheingold’s credentials to teach the course: he is not sanctioned by any university (although he does call what he does — modestly — “Rheingold U”), and there Read More

Science in Art & Design: Justin Taylor’s “The Gospel of Anarchy”

Posted 07 Oct 2011 / 0

There are so many science books that I want to read that I frequently neglect to read fiction. This is too bad, because good fiction can be as rich with interesting hypotheses about human nature and evolution as any book illuminating evolutionary theory. Towards the end of thinking about how my field informs and can Read More

Costly signalling not so costly in the presence of comrades

Posted 23 Sep 2011 / 0

This month’s issue of PLoS Computational Biology contained an interesting article entitled “Signalling and the Evolution of Cooperative Foraging in Dynamic Environments“. Authored by Colin J. Torney, Andrew Berdahl, Iain D. Couzin (all of Princeton University), the article seeks to understand the ecological conditions under which costly signaling can evolve. Many animals emit signals to Read More

HOME, a documentary about the impacted Biosphere

Posted 18 Sep 2011 / 0

I just watched the video Home, a production of Yann Arthus-Bertrand and his Good Planet Foundation. Composed solely of high-quality panoramic images intensified by a soaring new-age soundtrack, the film provides viewers with a fairly comprehensive overview of the earth’s ecosystems and the challenges to the future health of these ecosystems posed by human industry.

Eco-mysticism in the Ecology Classroom, Discontinuity in Evolutionary Theory

Posted 17 Sep 2011 / 0

After many semesters teaching an introductory Ecology course to non-majors, I have gotten a pretty good sense of the misconceptions that they bring to the subject. Most students receive little or no high school education in ecology: the majority of secondary school biology curricula are still predominantly organismal in their approach, with ecology and maybe Read More

Naturalistic Fallacy: 1, Sam Harris: 0

Posted 15 Sep 2011 / 2

For those who don’t know Sam Harris, he is a rather famous critic of theism who often invokes science and broad rationalism in his arguments for the abandonment of organized religion. Along with Christopher Hitchens, Daniel Dennett, and Richard Dawkins he is sometimes known as one of the “four horsemen of the neo-atheiest movement” (Wilson Read More

Patterns in mussel beds may reflect interaction between individual behavior and emergent environmental patterns

Posted 09 Sep 2011 / 0

Mussel beds off of Polzeath, United Kingdom (photo by Andy F) Natural selection is often oversimplified as the effect of the outside environment on the survival and reproduction probability of individual organisms. In the end this perspective has some value: individual organisms either survive and reproduce or they do not. But along the way, an Read More

How the right wing co-opts research into the evolution of cooperation

Posted 20 Aug 2011 / 2

One of the ways that I keep up with my field these days (inasmuch as that is even possible given the pace of innovation and activity) is by using Google Alerts. For those of you who are not familiar with the service, it allows you to receive updates via e-mail every time that a new Read More

Rand and Nowak paper on antisocial punishment in public goods games

Posted 19 Aug 2011 / 2

Researchers who study cooperation cannot agree on the role that punishment plays in maintaining the widespread social cooperation observed in nature and human societies. As is true in any scientific discipline, the social experiences of scientists studying cooperation influence their hypotheses. And looking at the societies that we live in, it is easy to see Read More

Is humanity’s most dangerous technology debt?

Posted 11 Aug 2011 / 0

If there is a theme running through my diverse interests, it is stability. For those who understand how ecological systems and evolutionary processes work, this should be entirely unsurprising: the living systems that persist today are those that are stable at multiple levels. The interactions between populations in a community must be stable, individual organisms Read More
