“Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stranded, stuck fast, untimely wounded, or otherwise deflected from its life's quest of delivering a tiny charge of genetic material to the right partner at the right moment in order to perpetuate the only possible sequence of hereditary combinations that could result -- eventually, astoundingly, and all too briefly -- in you.”

“Consider the fact that for 3.8 billion years, a period of time older than the Earth's mountains and rivers and oceans, every one of your forebears on both sides has been attractive enough to find a mate, healthy enough to reproduce, and sufficiently blessed by fate and circumstances to live long enough to do so. Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stranded, stuck fast, untimely wounded, or otherwise deflected from its life's quest of delivering a tiny charge of genetic material to the right partner at the right moment in order to perpetuate the only possible sequence of hereditary combinations that could result -- eventually, astoundingly, and all too briefly -- in you.”

“Not only have you been lucky enough to be attached since time immemorial to a favored evolutionary line, but you have also been extremely- make that miraculously- fortunate in your personal ancestry. Consider the fact that for 3.8 billion years, a period of time older than the Earth's mountains and rivers and oceans, everyone of your forbears on both sides has been attractive enough to find a mate, healthy enough to reproduce, and sufficiently blessed by fate and circumstances to live long enough to do so. Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stranded, stuck fast, untimely wounded, or otherwise deflected from it's life quest of delivering a tiny charge of genetic material to the right partner at the right moment in order to perpetuate the only possible sequence of hereditary combinations that could result - evetually, astoundingly, and all to briefly- in you.”

“Take a moment from time to time to remember that you are alive. I know this sounds a trifle obvious, but it is amazing how little time we take to remark upon this singular and gratifying fact. By the most astounding stroke of luck an infinitesimal portion of all the matter in the universe came together to create you and for the tiniest moment in the great span of eternity you have the incomparable privilege to exist.”

“I glanced at my watch - it was two minutes to eleven; just right for lunch when and if we ever got to the godforsaken lodge - and took some comfort from the thought that at least I still had my wits about me. Or at least I felt as if I did. Presumably, a confused person would be too addled to recognize that he was confused. Ergo, if you know that you are not confused then you are not confused. Unless, it suddenly occurred to me - and here was an arresting notion - unless persuading yourself that you are not confused is merely a cruel, early symptom of confusion. Or even an advanced symptom. Who could tell? For all I knew I could be stumbling into some kind of helpless preconfusional state characterized by the fear on the part of the sufferer that he may be stumbling into some kind of helpless preconfusional state. That's the trouble with losing your mind; by the time it's gone, it's too late to get it back.”

“Marrying cousins was astoundingly common into the nineteenth century, and nowhere is this better illustrated than with the Darwins and their cousins the Wedgwoods (of pottery fame). Charles married his first cousin Emma Wedgwood, daughter of his beloved Uncle Josiah. Darwin's sister Caroline, meanwhile, married Josiah Wedgwood III, Emma's brother and the Darwin siblings' joint first cousin. Another of Emma's brothers, Henry, married not a Darwin but a first cousin from another branch of his own Wedgwood family, adding another strand to the family's wondrously convoluted genetics. Finally, Charles Langton, who was not related to either family, first married Charlotte Wedgwood, another daughter of Josiah and cousin of Charles, and then upon Charlotte's death married Darwin's sister Emily, thus becoming, it seems, his sister-in-law's sister-in-law's husband and raising the possibility that any children of the union would be their own first cousins.”

“There’s something satisfying, I think,’ Evans said, ‘about the idea of light travelling for millions of years through space and just at the right moment as it reaches Earth someone looks at the right bit of sky and sees it. It just seems right that an event of that magnitude should be witnessed.”
