Quotes About Genes

Stress can alter the expression of genes, which can affect the response to stress and so on. Human behavior is therefore unpredictable in the short term, but broadly predictable in the long term.

What is truly revolutionary about molecular biology in the post-Watson-Crick era is that it has become digital...the machine code of the genes is uncannily computer-like.' -Richard Dawkins

Because bodies do not replicate themselves but are grown, whereas genes do replicate themselves, it inevitably follows that the body is merely an evolutionary vehicle for the gene, rather than vice versa.

It is genes that allow the human mind to learn, to remember, to imitate, to imprint, to absorb culture, and to express instincts. Genes are not puppet masters or blueprints. Nor are they just the carriers of heredity. They are active during life;

É claro que não há um único gene, mas há algo infinitamente mais enaltecedor e magnífico: toda uma naturza humana, flexivelmente pré-ordenada em nossos cromossomos e indiossincrática de cada um de nós. Todo mundo tem uma única e distina natureza endógena. Um self.

An extraordinarily nimble synthesist, Ridley leaps from chromosome to chromosome in a handy summation of our ever increasing understanding of the roles that genes play in disease, behavior, sexual differences and even intelligence. More important, though, he addresses not only the ethical quandaries faced by contemporary scientists but the reductionist danger in equating inheritability with inevitability." —The New Yorker

It is pure fatalism, undiluted by environmental variability. Good living, good medicine, healthy food, loving families or great riches can do nothing about. Your fate is in your genes. Like a pure Augustinian, you go to heaven by God's grace, not by good works. It reminds us that the genome, great book that it is, may give us the bleakest kind of self-knowledge: the knowledge of our destiny, not the kind of knowledge that you can do something about, but the curse of Tiresias.

We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes. This is a truth that still fills me with astonishment. Richard Dawkins, The Selfish Gene

It makes more sense to see the body as serving the needs of the genes than vice versa. Bottom–up.

In effect, since the process of natural selection is one of extracting useful information from the environment and encoding it in the genes, there is a sense in which you can look on the human genome as four billion years' worth of accumulated learning.

And there are genes that can be used to write the history of human migrations in the last few thousand years. From four billion years ago to just a few hundred years ago, the genome has been a sort of autobiography for our species, recording the important events as they occurred.

The body is the victim, plaything, battleground and vehicle for the ambitions of genes.

The phenomena we refer to as intelligence may be a byproduct of intergenomic conflict between genes mediating offense and defense in the context of language', write Rice and Holland.

Different versions of genes rise and fall in popularity driven often by the rise and fall of diseases. There is a regrettable human tendency to exaggerate stability, to believe in equilibrium.

Indeed, their bodies are designed with planned obsolescence called ageing that causes them to decay after they reach breeding age – or, in the case of squid or Pacific salmon, to die at once. None of this makes any sense unless you view the body as a vehicle for the genes, as a tool used by genes in their competition to perpetuate themselves. The body's survival is secondary to the goal of

Our minds have been built by selfish genes, but they have been built to be social, trustworthy and cooperative. That is the paradox this book has tried to explain. Human beings have social instincts. They come into the world equipped with predispositions to learn how to cooperate, to discriminate the trustworthy from the treacherous, to commit themselves to be trustworthy, to earn good reputations, to exchange goods and information, and to divide labour.

He was my father. I own half his genes, and all of his history. Believe this: the mistakes are part of the story. I am born of a man who believed he could tell nothing but the truth, while he set down for all time the Poisonwood Bible.

Engineered genes don't play by the rules that have organized life for three billion years (or, if you prefer, 4,004). And in this case, winning means loser takes all.

This power of choice means that we are not merely a product of our past or of our genes; we are not a product of how other people treat us. They unquestionably influence us, but they do not determine us. We are self-determining through our choices. If we have given away our present to the past, do we need to give away our future also?

Ancient history is always colliding with the present in the most literal sense: our genes, our language, our culture all stamp the present moment with the imprint of the distant past.

Of course genes can't pull the levers of our behavior directly. But they affect the wiring and workings of the brain, and the brain is the seat of our drives, temperaments and patterns of thought. Each of us is dealt a unique hand of tastes and aptitudes, like curiosity, ambition, empathy, a thirst for novelty or for security, a comfort level with the social or the mechanical or the abstract. Some opportunities we come across click with our constitutions and set us along a path in life.

Contrary to popular belief, the gene-centered theory of evolution does not imply that the point of all human striving is to spread our genes.

As far as the language instinct is concerned, the correlation between genes and languages is a coincidence. People store genes in their gonads and pass them to their children through their genitals; they store grammars in their brains and pass them to their children through their mouths. Gonads and brains are attached to each other in bodies, so when bodies move, genes and grammars move together. That is the only reason that geneticists find any correlation between the two.

Human vice is proof that biological adaption is, speaking literally, a thing of the past. Our minds are adapted to the small foraging bands in which our family spent ninety-nine percent of its existence, not the topsy-turvy contingencies we have created since the agricultural and industrial revolutions. [...] People do not divine what is adaptive for them or their genes; their genes give them thoughts and feelings that were adaptive in the environment in which the genes were selected.
