Posted 10 Nov 2015 / 0

Image from PNAS Proceedings of the National Academy of Sciences “Topography of social touching depends on emotional bonds between humans” (Suvilehto et al. 2015) This is a really clever study in that it aggregates a lot of data that is collected rather efficiently from a lot of participants. This makes the results robust for this Read More

Jonathan Haidt on the business advantage of being ethical

Posted 10 Nov 2015 / 0

This is a fascinating talk by Jonathan Haidt, a psychologist situated within one of the most prestigious business schools in the world whose research focuses on morality and emotion. I can’t help but be impressed when someone addressing business concerns leads with biology, and Haidt does a good job of summarizing the “disruptive cooperation” (read: competitively-superior Read More

That beard and deep voice may be to put him in his place, not attract her

Posted 09 Nov 2015 / 0

There have been a lot of evolutionary psychology experiments that have tried to define both female and male attractiveness to the opposite sex, an indirect way to get at the nature of sexual selection in humans. A new study published in Behavioral Ecology reminds us that sexual selection is not the only process that has Read More

Review of William B. Provine’s “The ‘Random Genetic Drift’ Fallacy”

Posted 05 Nov 2015 / 5

Just about a year ago, I got an unusual email. It was from William Ball Provine, a well-known historian of science most famous for his work on the modern evolutionary synthesis. Provine was especially well-known to me as the Ph.D. advisor to Greg Graffin of the punk band Bad Religion; although this is a story Read More

Did the population bombers drive China into cultural crisis?

Posted 05 Nov 2015 / 0

Image courtesy of Wikimedia Commons The Los Angeles Times “China drops its ‘one-child’ policy, now let’s ban the ‘population bomb’” Great op-ed that makes it really clear that impact is a function of not just the number of people on the earth but also the resources those people consume (affluence) and technologies used to produce Read More

Polygyny: the culture we dislike might not be the culture that is evolutionarily disfavored

Posted 02 Nov 2015 / 0

There’s a new paper out in the Proceedings of the National Academy of Sciences by David W. Lawson and colleagues that looks at whether the cultural practice of polygyny is disadvantageous. It’s a question that should be fascinating to anyone who is interested in sexual conflict or cultural evolution. At first glance, polygyny appears to be Read More
