Chimpanzees. So like us, we are both captivated and repelled. As we move through the looking glass into their world we are transformed. Chimpanzees, our forest-dwelling counterparts, unite us with the rest of nature. Eerily, they recall our prehistoric ancestors. Their social life reflects ours, too. With paramilitary patrols political struggles for power and gain even outright wars. The tender affection they show for one another their gestures and expressions all seem strangely familiar. Their invention of tools forced us to redefine what sets humanity apart from the beast. And now we discover that chimps developed not only tools, but entire cultures which they pass on to their young. Even medicine seems within their grasp And when stalked by death, they seem to feel a sorrow we can share. With a shiver of recognition, we glimpse the mind of the chimp and realize we are not alone. Come with us on a voyage of discovery, a journey into our collective past.
