Chimpanzees, our closest relatives, cannot triangulate punishment

Posted 20 Sep 2012 / 0

Proceedings of the National Academy of Sciences “No third-party punishment in chimpanzees” This is pretty astonishing, but perhaps not entirely surprising. As numerous other studies have shown, there are many qualitative differences in the cognition and resulting behaviors of humans and chimpanzees. Whether the fact that chimps do not maintain a sense of ‘social justice’ Read More

What’s ironic is that the creationists do not realize that we evolutionists might be trying to understand their success

Posted 20 Sep 2012 / 0

CreationRevolution “If Morality Evolved, Is It Righteous?” It is striking how this reaction lacks any self-consciousness. Research like that referred to in this post is a potential means of understanding how religions and their particular constructed righteousness (in other words their morals, what they believe ought to be) can succeed.

Agent-based modeling instead of game theory: I agree!

Posted 20 Sep 2012 / 0

The Society Pages “Progressing from game theory to agent based modelling to simulate social emergence” This is a nice albeit pretty choppy explanation for why we should not listen to orthodox/traditional game theorists. The only argument I see missing here is that game theory relies on the assumption of a well-mixed population: even the Prisoner’s Read More

Punishment, properly rewarded, can promote cooperation without corruption

Posted 20 Sep 2012 / 0

Public Library of Science ONE “Evolving Righteousness in a Corrupt World” In the race to build the next over-simplified model of cooperative dynamics, it will be interesting to see how the media runs with this one. Is this a “scientists discover the evolutionary rationale for honorable police” moment? I think it is important to take Read More

Want a good gauge of how much humans pollute waterways? Just measure for caffeine!

Marine Pollution Bulletin “Occurrence and concentration of caffeine in Oregon coastal waters” Coffee addicts worldwide can be proud of this result: you are leaving a “pissprint” on local waters.

Does anthropogenic change make natives into invaders?

Posted 19 Sep 2012 / 0

Frontiers in Ecology and the Environment “Native invaders – challenges for science, management, policy, and society” This article makes an important point: the “alien” criteria for invasives is a bit arbitrary when the problem with invasives is their ability to explode in population and inordinately impact other populations. Perhaps we need to re-think the way Read More

Are the Sentinelese the last untouched hunter-gatherer culture?

Posted 19 Sep 2012 / 0

Frontiers in Ecology and the Environment “A world of their own” This is an absolutely fascinating article. I was not aware that there were any cultures outside of Amazonia that have maintained such isolation. As Burton points out, we need to decide how to balance our curiosity and potential charity with respect for the wishes Read More
