We, humans, pride ourselves on many things.

On being smart/intelligent. And on being the only animals able to brag about their achievements with their peers…

But what is it that qualifies us as humans?
That would, of course, depend on what a human really is…

OK, let me use another tack.
What are we really good at? What sets us apart from the rest of the animals?

Practical intelligence? Our ability to solve really complicated problems?

Then watch this wild New Caledonian Crow treating itself to a piece of meat.

Our ability to figure new meaning and to overcome our natural impulses?

Then read about Sheba the Chimp using language to suppress her greed:

In a celebrated study that investigated impulse control, Sally Boysen of Ohio State University asked chimps to choose between two dishes of M&Ms®.

SALLY BOYSEN: Now, you watch real carefully. We’re going to put one, two, three, four down here. Are you watching, Miss Priss? Sheeby? And we’re going to put two in here.

Give those to Sarah. Okay.

Well, I have to give these to Sarah, and Sheeba gets two. So Sarah gets four and Sheba only gets two. Aw, too bad.

NARRATOR: The twist was that the chimp got the candy she didn’t point to. Could the chimp learn to resist her impulse to reach for the bigger pile?

SALLY BOYSEN: You want Sarah to have these? It’s okay, it’s okay. You get to have that one. Yeah, Sarah gets five, and Sheba gets one. Oh, that is such a shame.

NARRATOR: Amazingly, chimps never overcame their greedy urges. They always reached for more and, so, ended up with less.

SALLY BOYSEN: And Sheba gets two, so Sarah gets four. See?

NARRATOR: Impulse studies have also been run on humans. In a classic experiment from the 1970s, a researcher gave a four-year-old a simple choice.

RESEARCHER : So, if you wait for me to get back, I’ll give you this bowl with all of these gummy bears, okay? But if you can’t wait, you can push that button, like this, and then I’ll come back and you can have this bowl with just this one gummy bear, okay? Okay, I’ll be right back.

NARRATOR: According to an inconclusive but intriguing study, the longer children resisted temptation, the higher their S.A.T. scores were years later. In any case, the differences between people are small compared to the gap separating humans and apes.

BRIAN HARE: Maybe one of the first things that happened during our species evolution is we became much less emotionally reactive. And maybe that’s one of the big differences that may explain why we solve problems so differently. We sort of got control of our emotions.

NARRATOR: Can apes be given skills to help them master their emotions? Sally Boysen trained a chimp to understand numerals. Then she repeated her M&Ms experiment, but now offered different pairs of numerals rather than treats.

SALLY BOYSEN: You want to give two to Sarah? Okay. Two goes to Sarah, and you get six.

NARRATOR: Remarkably, chimps were now able to learn what they couldn’t before: point to the smaller number to get the bigger prize.

Symbols can make you free. They can help distance an ape from its impulses. But outside of the lab, apes don’t seem to use symbols. Still, ape minds seem to share many of the amazing features of the human mind.

There is a video which depicts all this. Click on this link and see if it’s available “in your area.” http://www.pbs.org/wgbh/nova/nature/ape-genius.html.

How about our consciousness? Our ability to ‘observe ourselves in the act of observing‘.
Well, that alone wouldn’t have made us any more special than an octopus…

But what if our individuality resides in us having taken all three to ‘a different level’? One which hasn’t yet been attained by anybody else? Not necessarily higher, mind you!

I’ll deal with ‘trade’ now and I’m afraid you’ll have to come back for the rest.

‘Trade’ wasn’t even mentioned in those three examples?
What was the crow trying to do?
Feed itself? As in exchange matter with the ‘outside’?
What was Sheba trying to do?
Figure our what was going on? As in trading information with the surrounding world?

In this sense all living things are engaged in all forms of trading? And continue to do so for as long as they remain alive?
What did I tell you about us doing nothing really new? Only different?

OK, we had already figured out – long before Adam Smith described it as ‘division of labor’, that by dividing tasks amongst us we’ll be able to accomplish far more things than if we had attempted ‘individual autarky’. And then we had invented ‘trade’, as a manner of exchanging the different wares each of us was proficient in doing…
Wait! Even this is not really ‘new’!
Mother Nature had already invented sexual reproduction – a very extreme ‘division of labour’, a very long time ago…. but not before bacteria were already adept at ‘trading’ genetic information.
