Evolution may be too slow: British Columbia begins assisted migration of forests

Discover “The Transplanted Forest: A Bold Experiment in Preemptive Climate Adaptation” Given the chances that we will fail to prevent climate change, it seems like the Canadians have the right idea here. Ironic that industries that rely on stable climate are less apt to deny its reality.

National Geographic goes looking for heat-loving bacteria in a very cold place

Posted 26 Jun 2012 / 0

National Geographic “Life in an Icy Inferno” This is an interesting article from the “great extents to which scientists go to do their work” perspective, but disappointingly it was not all that clear in this article what the purpose of finding thermophilic bacteria in Antarctica might be. I suppose that plenty of NatGeo expeditions can Read More

National Geographic feature on “Vanishing Languages”

Posted 26 Jun 2012 / 0

National Geographic “Vanishing Languages” I am fascinated and a bit horrified by the process of language extinction described in this article.

It seems as though we are headed towards a Read More

Peter Turchin on Steven Pinker’s “Grand Deception” hypotheses

Posted 26 Jun 2012 / 0

Social Evolution Forum “The ‘Big Mistake’ and ‘Grand Deception’ Hypotheses: Alternatives to CMLS?” These are flaws in Pinker’s arguments that I failed to identify in my own critique, and Turchin prevents some valuable insights. This idea that the human mind can be so easily parasitized or ‘cuckolded’ by ideas is strange, casting ideas and culture as Read More

Steven Pinker makes it clear that he is not a “group selectionist”

Posted 26 Jun 2012 / 5

Frequently I feel like I am listening to an early 2000’s George W. Bush speech when the ‘opponents of group selection’ step up to the podium. Seemingly, you are either “with us or against us” when it comes to considering selection acting at a level above the individual. As someone who is open to thinking Read More
