A bonobo called Kanzi has been observed to create a stack of firewood, start a fire (admittedly with matches he probably hasn't made himself), and cook food (again, marshmallows and burgers, which have admittedly been given to him by his human handlers). Despite these helpful additions by humans, there is one thing Kanzi has done all by himself, and that's learn how to do this.
Though human handlers have provided him with some tools and regular viewings of the movie Quest for fire, Kanzi learned how to light the fire and cook the food all by himself, and is teaching his son Teco to do it too. Watch him in action here.
These are only four examples out of many more discovered by scientists. Many skills and traits previously thought to be exclusively human have been found in nature – from crows' extraordinary abilities to use tools to spiders deceiving potential mates by lying – which are causing us to rethink exactly how we evolved and what makes us so special... if anything at all.
