Why it stood up nobody knows, but once upright it found it could use its hands to fashion tools from sticks and stones. So it stayed standing up. And once it decided to stay standing up, its brain started to grow. Why its brain started to grow nobody knows, but with a bigger brain the ape, which was by now an ape-man, could make better tools and even speak. Why it started to speak nobody knows. And by then it wasn’t an ape-man any more, but a human. And those humans with the most developed brains – Homo sapiens – used their cunning to spread throughout the world. All the many other kinds of human and ape-man died. Why they died nobody knows.
