“Something in the order of a 107 billion modern humans have existed, though this number depends on when exactly you start counting. All of them – of us – are close cousins, as our species has a single African origin. We don’t quite have the language to describe what that really means. It doesn’t, for example, mean a single couple, a hypothetical Adam and Eve. We think of families and pedigrees and genealogies and ancestry, and we try to think of the deep past in the same way. Who were my ancestors? You might have a simple, traditional family structure or, like me, it could be handsomely untidy, and its tendrils jumbled like old wires in a drawer. But no matter which, everyone’s past becomes muddled sooner or later.”

“life has existed on Earth for about 3.9 billion years. The species Homo sapiens, of which you are a member, emerged a mere 300,000 years ago as far as we know, in pockets in east and north Africa. Writing began about 6,000 years ago, in Mesopotamia, somewhere in what we now call the Middle East.”

“Man is literally split in two: he has an awareness of his own splendid uniqueness in that he sticks out of nature with a towering majesty, and yet he goes back into the ground a few feet in order blindly and dumbly to rot and disappear forever.”
