Greg Laden has up the latest Four Stone Hearth. In the spirit of the holiday, it’s ‘Four Stone Hearth Anthropology Blog Carnival: The Fourth Of July Everything is Just Fine We’ve Got It Under Control In America Edition.‘ Lots of good anthropology.

I’ll be quoting from Laden’s own ‘Morning Sickness is an Adaptation, not a … Sickness‘ in my upcoming lecture on evolutionary perspectives on sex and sexuality. I also particularly liked The Myth of Cultural Miscommunication at Savage Minds. The post, by Kerim, uses a good video to point out why the problem with ‘miscommunication’ in the Iraq war isn’t always lack of knowledge; sometimes it’s simply lack of concern for the Iraqis and the relatively simple things that they are trying to communicate. Finally, Afarensis has a nice discussion of technological development of projectile points, and the issue of ‘optimizing’ design, at ‘Return of the Projectile Points.’ But please check out the original as there’s a lot of good material in this one, and happy 4th of July to all the Yanks!
