Mars Dust

Do chimpanzees have watchers in their natural habitat? I don't know for sure, but many groups of social animals have members with such roles. Ground-squirrel colonies have pretty obvious 'sentries' posted when they're out foraging. The point, though, is that the chimp's behaviour was based on some kind of awareness of his comrade's perceptions; I think most animals and birds give their alarm cries instinctually, without considering who really needs warning. You won't see a ground-squirrel doing a head-count before it starts squeaking and flicking its tail as you approach. That's exactly what I was driving at. I was trying to find out how the behavior of the chimpanzee indicated this awareness, whereas similar behavior of other animals does not (indicate awareness). Are there any links on the web to this experiment? Lots of Greetings! Volker |
