There is a popular image of human evolution that you’ll find all over the place … On the left of the picture there’s an ape … On the right, a man … Between the two is a succession of figures that become ever more like humans … Our progress from ape to human looks so smooth, so tidy. It’s such a beguiling image that even the experts are loath to let it go. But it is an illusion.
