When we were young, we believed in a Story. First there was Australopithecus, a toolless, speechless, walking chimp. He begat a brave pioneer called Homo erectus, a handy sort of chap who at least had decent looking tools and invented fire. He begat two sons: a hairy, primitive savage one called Neanderthal Man, who deservedly came to a sticky end. And a tall, cool handsome one which called itself Homo sapiens (“the wise man”), in one of the most outrageous acts of vanity and self-delusion in history.
The truth turned out to be far more complicated. Even looking at the story of the last 500 000 years , when everyone was about as modern as you can get. First Neanderthals have been getting steadily cleverer for the last forty years or so. They probably had language, clothes and y even art, goddammit. Along came another relative, the Denisovans who were similarly equipped. And then came the geneticists lead by the inimitable Professor Paabo, whose discoveries have upended everything , blurred every category and wiped every line. Latest instalment in this trope comes from the discoveries of the learned Professor Cousins of Cambridge University which we channel both from Jonathan Chadwick of the Mail[1] and for those with a little more time, the original paper itself [2] The story of the last million years or so is not of some heroic hero on a quest for self-improvement. But bunches of largely helpless bipeds pushed hither and thither by the vagaries of climate and geology, splitting, meeting and breeding; spawning a mishmash of different types which their distant descendants come along and label with important- sounding names. And we think we see a pattern in all this.
Firstly :you know a lot less than you think you do. We have been tracking human evolution for nearly sixty years now, so we can be fairly confident about that statement. Secondly: there is always something buried out there which is going to upend everything you know; so stay cautious. Thirdly: someone in another field is going to park their intellectual tanks on your lawn sooner or later, reducing your omniscient learning to at most part of things, not the whole of it. And finally:-human evolution makes a pretty good paradigm for all other learning. Not just hard sciences, not just social sciences but also things like history and economics. Beware of anyone who knows the answers, because they are not telling the truth.
