Here it is: the cover of this week's People magazine, the iconic shot of Hollywood's alpha couple with their newborn twins. Rights to the photos-which show a Madonna-like Angelina Jolie with Brad Pitt as middle-aged and goateed architect and two blob-like infants-were sold for more than $14m, more than double the price paid for any other set of celebrity baby photos. If anyone ever doubted that human beings were descended from monkeys, obsessed by social hierarchy, then the extraordinary public and media interest in these very ordinary images ought to resolve the question once and for all.
