Friday Monkey Blogging: Chimps Compile Nixon-Style 'Enemies List'
As I mentioned a couple of weeks ago, I have started a regularly recurring blog entry meme every Friday afternoon, inspired by Bruce Schneier's regular series of "Friday Squid Blogging" posts, and my very own maddening Monkey Theory.
Here is this week's installment.
Ewen Callaway writes on New Scientist Environment:
Chimpanzees have at least one thing in common with the late US president Richard Nixon: tracking those who do them favours and putting those who don't come up to scratch on an "enemies list".More here.
Nearly 3000 hours of observations of wild chimpanzees show that they keep tabs on which of the troop has groomed them the most – returning the favour to frequent groomers, while freezing out the selfish ones.
