A creative bonobo caught making tools slides in at number 9 in our best videos of 2012 countdown.
Kanzi just wanted a snack. Eviatar Nevo of the University of Haifa in Israel and colleagues locked some food inside a log - not to mess with the 30-year-old bonobo, but to see what he would come up with to retrieve it.
His solution? Making flints from stones then using them to drill into the log, a tactic that allowed him to successfully break into 24 different pieces of wood. Not all bonobos, however, seem to have the same knack for tool-making: Kanzi's companion got at the food twice but only by smashing the log on the ground.
Apart from crafting tools, Kanzi also paints, uses sign language and has even been seen making up words.
