What are some behaviors in chimpanzees that are different than those of humans?

Question

For example if you had to differentiate between a chimpanzee and a human based only on behavior, how would you do it?

Answer 1

It is a qualitative matter and not a quantitative one.

That means we show the same behaviors, but the degrees of the behaviors are different.

For example, Chimpanzees can comprehend cause and effect, if a happens then B.  They may even comprehend if a happens B happens then C happens.  But they many not comprehend if A happens then B happens then C happens then D happens.  

this seems to hold up with most cognitive behaviors.  If you've heard researchers, they usually say something like, chimpanzees have shown an ability to do a task similar to the ability of a 4 year old human, but a 7 year old human is able to do something else which chimpanzees were unable to replicate.  

For something more concrete, you may say that chimpanzees do not have the physiological faculty for human like speech, even though they seem to have both the cognitive ability to comprehend and produce language at the level of a 7 year old.

Answer 2

At the zoo I have seen chimps throw S**t at people, pick their nose and eat it and throw up and then eat their barf, and m********e.  

I don't usually do that.  At least not in front of people.
