"Individuals are not stable things, they are fleeting. Chromosomes too are shuffled into oblivion, like hands of cards soon after they are dealt. But the cards themselves survive the shuffling. The cards are the genes. The genes are not destroyed by crossing-over, they merely change partners and march on. Of course they march on. That is their business. They are the replicators and we are their survival machines. When we have served our purpose we are cast aside. But genes are denizens of geological time: genes are forever."

"The human body when kept in an indoor environment of low lux light will not realize that it is daytime, as it cannot sense the increasing levels of daylight that the genetics are accustomed to. As such, by late morning your body may start sending a signal for you to sleep!"

"Air freshener is man's pitiful attempt to have his food smell as good, after digestion, as they did, before ingestion."

"The sleeping style of each organism is exquisitelyadapted to the ecology of the animal. It is conceivable that animals who are too stupid to be quiet on their own initiative are, during periods of high risk, immobilized by the implacable arm of sleep."

"Periods are a period when nature forces prostitutes to go on leave."

"When I say that human beings are just gene machines, one shouldn't put too much emphasis on the word 'just.' There is a very great deal of complication, and indeed beauty in being a gene machine."

"The human population would probably be way less than a thousand, if ejaculation were not usually accompanied by an orgasm."

"A universe with a God would look quite different from a universe without one. A physics, a biology where there is a God is bound to look different. So the most basic claims of religion are scientific. Religion is a scientific theory."

"Religion is about turning untested belief into unshakable truth through the power of institutions and the passage of time."

"If the history-deniers who doubt the fact of evolution are ignorant of biology, those who think the world began less than ten thousand years ago are worse than ignorant, they are deluded to the point of perversity. They are denying not only the facts of biology but those of physics, geology, cosmology, archaeology, history and chemistry as well."

"I am fascinated by the evolution of language, and how local versions diverge to become dialects like Cornish English and Geordie and then imperceptibly diverge further to become mutually unintelligible but obviously related languages like German and Dutch. The analogy to genetic evolution is close enough to be illuminating and misleading at the same time. When populations diverge to become species, the time of separation is defined as the moment when they can no longer interbreed. I suggest that two dialects should be deemed to reach the status of separate languages when they have diverged to an analogously critical point: the point where, if a native speaker of one attempts to speak the other it is taken as a compliment rather than as an insult."

"Evolution could so easily be disproved if just a single fossil turned up in the wrong date order. Evolution has passed this test with flying colours."

"Something about the cultural tradition of Jews is way, way more sympathetic to science and learning and intellectual pursuits than Islam."

"If God wanted to forgive our sins, why not just forgive them, without having himself tortured and executed in payment-thereby, incidentally, condemning remote future generations of Jews to pogroms and persecution as 'Christ-killers': did that hereditary sin pass down in the semen too?"

"The fact that life evolved out of nearly nothing, some 10 billion years after the universe evolved out of literally nothing, is a fact so staggering that I would be mad to attempt words to do it justice."
