This link to a news update in Nature is only available for free for a short time, so read it while you can. http://www.nature.com/news/2006/060807/full/060807-4.html I'm always fascinated by animal behavior, mainly because many people some time use the argument against something as being "not natural", as IF everything that's "natural" or in nature is something that's good and must be followed. In any case, I was reading this with fascination till the end, when I couldn't stop laughing at the very last "editorialization" by the writer, saying "So, like politicians, meerkats work for the good of the party, but are vicious back-stabbers when they get the chance." Touche! :) Zz.
