They have a talent for mathematics , being able to distinguish "greater than" and "less than" quantities and order objects according to their size.
An ability that resides in the prefrontal cortex, where the arithmetic ability of humans is located.
They have emotional reactions similar to ours , for example, when they make wrong decisions.
These primates grimace and have strong tantrums and tantrums when, after taking a risk, they fail. They may also experience feelings of frustration and regret.
They have an innate sense of justice and injustice , given that they exhibit cooperative behavior: they show a preference for equitable distribution of rewards.
They are aware of themselves. Like humans, they can anticipate the effects of their own actions, reflect on what they are thinking, and act accordingly – a skill known as metaknowledge.
They are capable of learning human language. The American couple of Deborah and Roger S. Fouts dedicated most of their lives to working with chimpanzees.
They not only learned to communicate with sign language, but also to lie, to say "I am sad", to ask for forgiveness and even to make poetry.
