> I doubt you find yourself needing to look at the president’s ears to tell if it’s Bush or Reagan Indeed! But I was really just listing the discriminators for the benefit of people who perhaps haven't looked at chimps very hard. For a few of the chimps, I can look and immediately say "that's Bart" or "that's Thelma". This may of course be my mind having internalised a few distinct 'settings' of the discriminators. But the overall effect, coming back to my original point, is that apparently without conscious thought I can recognise specific individual non-humans. The Primate Care Staff, who work with these individuals 24/7, have very good at-a-glance recognition for the entire community.
