Jason Collins questions the utility-to-fitness conversion

Posted 21 Jun 2012 / 0

Evolving Economics “Gandolfi, Gandolfi and Barash’s Economics as an Evolutionary Science” Great commentary on the fitness-maximizing behavior (or lack thereof) by the ultra-rich. Clearly humans are maximizing something other than their genetic fitness when they seek utility.

Scientific American “Why We Help”

Posted 21 Jun 2012 / 1

The July issue of Scientific American features a cover story written by Martin A. Nowak called “Why We Help“. This very short article contains a brief review of Nowak’s “five rules” for cooperation, a little bit of connection to experimental work in real organisms, and some hazy conjecture concerning what makes humans cooperate. It seems as Read More

Who is the bigger bioterrorist, man or nature?

Posted 21 Jun 2012 / 0

Nature “Engineering H5N1 avian influenza viruses to study human adaptation” I think that the most interesting idea expressed by this article is: In considering the threat of bioterrorism or accidental release of genetically engineered viruses, it is worth remembering that nature is the ultimate bioterrorist. There is so much in this single statement, so many Read More

Posted 20 Jun 2012 / 0

Proceedings of the National Academy of Sciences “Delayed paternal age of reproduction in humans is associated with longer telomeres across two generations of descendants” Science Daily “Offspring of Older Fathers May Live Longer” What I find fascinating here is the hypothesized adaptive value of this genetic discovery: telomeres may be a molecular mechanism by which Read More
