. So you reject a gorilla that use sign language and who told mr Rogers that she loved him . You pretend that chimps don’t make Spears and hunt with them . The real difference between the other apes and humans is that we’ll cooperate. They haven’t quite figured that out.
Not entirely true actually. They have in fact figured that out.
What they haven't figured out though, is the importance of "the greater good". A chimp will only cooperate with another chimp, if he gets immediate reward for it.
I remember this social experiment...
It was kind of a puzzle.
2 chimps were in a cage. Just outside the cage, a plate with grapes (or whatever).
A rope was put around the plate, with the ends reaching inside the cage - but too far apart for one chimp to pull both (to get the plate closer to the cage so they were able to reach the food).
If you pulled on one end, the other end off course came out of the cage and then there was no way left to reach the food.
When the experiment starts, only one chimp is let in the cage. He tries to get to the food and quickly realises that he can't do it alone. This chimp
himself, then lets the other chimp into the cage through a door. They instantly cooperate. Both chimps take an end of the rope and pull.
But then, something happens. The dominant chimp of the two goes for the food and doesn't share.
A bit later, the experiment was repeated. Again the dominant chimp starts alone in the cage. Quickly realising it's the same puzzle, he lets the other chimp in. The dominant chimp moves into position to pull the rope. The other...... does not.
The first experience taught him that he'll only be helping the other guy get food. He'll get nothing. So he won't help.
Chimps seem to only bother with things that yield immediate returns.
Another experiment comes to mind, which is quite fascinating imo, as it would seem to illustrate that young chimps are actually smarter then human children.
There's this black plastic box with some candy in it. The subjects (young chimps and humans) are shown a series of "actions/manipulations" with the box, at the end of which a piece of candy comes out of the box. Both the chimps and humans carefully repeat the series of actions step by step, to get the candy.
Next up, the exact same experiment with the exact same box. ONly this time, the box is transparant. Because it is transparant, it also becomes obvious that half of the actions/manipulations are actually not necessary at all, as they don't do anything. They are completely useless to get to the candy.
Here's the not-so-obvious result:
- chimps immediatly stop doing the unecessary steps. They only do the steps that are actually required to get the candy.
- human children... don't. They continue doing the entire series, while half of the series is completely useless.
The theory is, that we humans are so "smart", because we spend our lives learning everything - including those things that seem entirely useless at the time that we learn them.
While chimps only do and learn the absolute required minimum - and even then also only if it yields immediate results.
Lots of such experiments can be seen on youtube.
