Your genetics load the gun. Your lifestyle pulls the trigger.

You and I don't have the same genetics, we don't live in the same places, but we can have the same basic attitude - being comfortable in our skin.

A four-letter alphabet called DNA.

After a handful of geeks sequenced the Neanderthal genome and found a 2% match, they opened the flood gates to hundreds of geneticists that now make a living telling you what diseases you inherited from an extinct Arctic ape.

After Lincoln became president he campaigned for colonization, and even in the midst of war with the Confederacy found time to work on the project, appointing Rev. James Mitchell as Commissioner of Emigration, in charge of finding a place to which blacks could be sent. On August 14th, 1862, he invited a group of black leaders to the White House to try to persuade them to leave the country, telling them that “there is an unwillingness on the part of our people, harsh as it may be, for you free colored people to remain with us.” He urged them to lead their people to a colonization site in Central America. Lincoln was therefore the first president to invite a delegation of blacks to the White House—and did so to ask them to leave the country. Later that year, in a message to Congress, he argued not just for voluntary colonization but for the forcible removal of free blacks. Lincoln’s successor, Andrew Johnson, shared these anti-black sentiments: “This is a country for white men, and by God, as long as I am President, it shall be a government for white men.” Like Jefferson, he thought whites had a clear destiny: “This whole vast continent is destined to fall under the control of the Anglo-Saxon race—the governing and self-governing race.” Before he became president, James Garfield wrote, “[I have] a strong feeling of repugnance when I think of the negro being made our political equal and I would be glad if they could be colonized, sent to heaven, or got rid of in any decent way . . . .” Theodore Roosevelt blamed Southerners for bringing blacks to America. In 1901 he wrote: “I have not been able to think out any solution to the terrible problem offered by the presence of the Negro on this continent . . . .” As for Indians, he once said, “I don’t go so far as to think that the only good Indians are the dead Indians, but I believe nine out of ten are, and I shouldn’t inquire too closely into the health of the tenth.” William Howard Taft once told a group of black college students, “Your race is adapted to be a race of farmers, first, last, and for all times.” Woodrow Wilson was a confirmed segregationist, and as president of Princeton he refused to admit blacks. He enforced segregation in government offices and was supported in this by Charles Eliot, president of Harvard, who argued that “civilized white men” could not be expected to work with “barbarous black men.” During the presidential campaign of 1912, Wilson took a strong position in favor of excluding Asians: “I stand for the national policy of exclusion. . . . We cannot make a homogeneous population of a people who do not blend with the Caucasian race. . . . Oriental coolieism will give us another race problem to solve and surely we have had our lesson.” Warren Harding also wanted the races kept separate: “Men of both races [black and white] may well stand uncompromisingly against every suggestion of social equality. This is not a question of social equality, but a question of recognizing a fundamental, eternal, inescapable difference. Racial amalgamation there cannot be.

A geneticist is a geek who claims to have proven through regression analyses that a Neanderthal had sex with your great-grandmother 50,000 years ago.

All modern humans are related to what scientists call "Mitochondrial Eve." This refers to our common matrilineal ancestor. She lived approximately 200,000 years ago and depending on how you estimate the length of a generation, we are only 5,000 to 10,000 generations from one another. To put it another way, each of us is a cousin of one another at most 10,000 times removed. And yes, Mitochondrial Eve lived in Africa, so, in a very real way, we are all Africans.

All sorts of changes in cellular machinery have shown up that have nothing to do with the sequence of DNA but still have profound, and heritable, impacts for generations to come. For example, malnourished rats give birth to undersized pups that, even if well fed, grow up to give birth to undersized pups. Which means, among other things, that poor old Lamarck was right—at least some acquired traits can be passed down.

Among the Founders, Thomas Jefferson wrote about race at greatest length. He thought blacks were mentally inferior to whites and biologically distinct: “[They] secrete less by the kidnies [sic], and more by the glands of the skin, which gives them a strong and disagreeable odor.” He hoped slavery would be abolished, but he did not want free blacks to remain in America: “When freed, [the Negro] is to be removed from beyond the reach of mixture.” Jefferson was one of the first and most influential advocates of “colonization,” or returning blacks to Africa. He also believed in the destiny of whites as a racially distinct people. In 1786 he wrote, “Our Confederacy [the United States] must be viewed as the nest from which all America, North and South, is to be peopled.” In 1801 he looked forward to the day “when our rapid multiplication will expand itself . . . over the whole northern, if not the southern continent, with a people speaking the same language, governed in similar forms, and by similar laws; nor can we contemplate with satisfaction either blot or mixture on that surface.

And so,' smiled the Witcher, 'I have no choice? I have to enter into a pact with you, a pact which should someday become the subject of a painting, and become a sorcerer? Give me a break. I know a little about the theory of heredity. My father, as I discovered with no little difficulty, was a wanderer, a churl, a troublemaker and a swashbuckler. My genes on the spear side may be dominant over the genes on the distaff side. The fact that I can swash a buckler pretty well seems to confirm that.

Ants have a powerful caste system. A colony typically contains ants that carry out radically different roles and have markedly different body structures and behaviors. These roles, Reinberg learned, are often determined not by genes but by signals from the physical and social environment. 'Sibling ants, in their larval stage, become segregated into the different types based on environmental signals,' he said. 'Their genomes are nearly identical, but the way the genes are used—turned on or off, and kept on or off—must determine what an ant "becomes." It seemed like a perfect system to study epigenetics. And so Shelley and I caught a flight to Arizona to see Jürgen Liebig, the ant biologist, in his lab.' The collaboration between Reinberg, Berger, and Liebig has been explosively successful—the sort of scientific story ('two epigeneticists walk into a bar and meet an entomologist') that works its way into a legend. Carpenter ants, one of the species studied by the team, have elaborate social structures, with queens (bullet-size, fertile, winged), majors (bean-size soldiers who guard the colony but rarely leave it), and minors (nimble, grain-size, perpetually moving foragers). In a recent, revelatory study, researchers in Berger’s lab injected a single dose of a histone-altering chemical into the brains of major ants. Remarkably, their identities changed; caste was recast. The major ants wandered away from the colony and began to forage for food. The guards turned into scouts. Yet the caste switch could occur only if the chemical was injected during a vulnerable period in the ants’ development. [...] The impact of the histone-altering experiment sank in as I left Reinberg’s lab and dodged into the subway. [...] All of an ant’s possible selves are inscribed in its genome. Epigenetic signals conceal some of these selves and reveal others, coiling some, uncoiling others. The ant chooses a life between its genes and its epigenes—inhabiting one self among its incipient selves.

Anything with blood in it can probably go bad. Like meat. And it’s the blood that makes me worry. It carries things you don’t even know you got.

We have lived in a world where the discoveries of physics and genetics are far more awe-inspiring, as well as infinitely more liberating, than the claims of any religion.

Adam & Eve have been degraded, reduplicated forever, photocopies of photocopies, mistakes copied, magnified, augmented.

A remarkably consistent finding, starting with elementary school students, is that males are better at math than females. While the difference is minor when it comes to considering average scores, there is a huge difference when it comes to math stars at the upper extreme of the distribution. For example, in 1983, for every girl scoring in the highest percentile in the math SAT, there were 11 boys. Why the difference? There have always been suggestions that testosterone is central. During development, testosterone fuels the growth of a brain region involved in mathematical thinking and giving adults testosterone enhances their math skills. Oh, okay, it's biological. But consider a paper published in science in 2008. The authors examined the relationship between math scores and sexual equality in 40 countries based on economic, educational and political indices of gender equality. The worst was Turkey, United States was middling, and naturally, the Scandinavians were tops. Low and behold, the more gender equal the country, the less of a discrepancy in math scores. By the time you get to the Scandinavian countries it's statistically insignificant. And by the time you examine the most gender equal country on earth at the time, Iceland, girls are better at math than boys. Footnote, note that the other reliable sex difference in cognition, namely better reading performance by girls than by boys doesn't disappear in more gender equal societies. It gets bigger. In other words, culture matters. We carry it with us wherever we go.

Asians are still a small minority—14.5 million (including about one million identified as part Asian) or 4.7 percent of the population—but their impact is vastly disproportionate to their numbers. Forty-four percent of Asian-American adults have a college degree or higher, as opposed to 24 percent of the general population. Asian men have median earnings 10 percent higher than non Asian men, and that of Asian women is 15 percent higher than non-Asian women. Forty-five percent of Asians are employed in professional or management jobs as opposed to 34 percent for the country as a whole, and the figure is no less than 60 percent for Asian Indians. The Information Technology Association of America estimates that in the high-tech workforce Asians are represented at three times their proportion of the population. Asians are more likely than the American average to own homes rather than be renters. These successes are especially remarkable because no fewer than 69 percent of Asians are foreign-born, and immigrant groups have traditionally taken several generations to reach their full economic potential. Asians are vastly overrepresented at the best American universities. Although less than 5 percent of the population they account for the following percentages of the students at these universities: Harvard: 17 percent, Yale: 13 percent, Princeton: 12 percent, Columbia: 14 percent, Stanford: 25 percent. In California, the state with the largest number of Asians, they made up 14 percent of the 2005 high school graduating class but 42 percent of the freshmen on the campuses of the University of California system. At Berkeley, the most selective of all the campuses, the 2005 freshman class was an astonishing 48 percent Asian. Asians are also the least likely of any racial or ethnic group to commit crimes. In every category, whether violent crime, white-collar crime, alcohol, or sex offenses, they are arrested at about one-quarter to one-third the rate of whites, who are the next most law-abiding group. It would be a mistake, however, to paint all Asians with the same brush, as different nationalities can have distinctive profiles. For example, 40 percent of the manicurists in the United States are of Vietnamese origin and half the motel rooms in the country are owned by Asian Indians. Chinese (24 percent of all Asians) and Indians (16 percent), are extremely successful, as are Japanese and Koreans. Filipinos (18 percent) are somewhat less so, while the Hmong face considerable difficulties. Hmong earn 30 percent less than the national average, and 60 percent drop out of high school. In the Seattle public schools, 80 percent of Japanese-American students passed Washington state’s standardized math test for 10th-graders—the highest pass rate for any ethnic group. The group with the lowest pass rate—14 percent—was another “Asian/Pacific Islanders” category: Samoans. On the whole, Asians have a well-deserved reputation for high achievement.

Anzick-1's "Clovis connection" is of immediate relevance to our quest here--which is that although Clovis did, at the limits of its range, extend into some northern areas of South America, its heartland was in North America. Intuitively, therefore, we would expect the Montana infant, a Clovis individual, to be much more closely related to Native North Americans than to Native South Americans. Further investigations, however, while reconfirming that Anzick-1's genome had a greater affinity to all Native Americans than to any extant Eurasian population, revealed it to be much more closely related to native South Americans than to Native North Americans!

At sixteen, you still think you can escape from your father. You aren't listening to his voice speaking through your mouth, you don't see how your gestures already mirror his; you don't see him in the way you hold your body, in the way you sign your name. You don't hear his whisper in your blood.

As long as museums and universities send out expeditions to bring to light new forms of living and extinct animals and new data illustrating the interrelations of organisms and their environments, as long as anatomists desire a broad comparative basis human for anatomy, as long as even a few students feel a strong curiosity to learn about the course of evolution and relationships of animals, the old problems of taxonomy, phylogeny and evolution will gradually reassert themselves even in competition with brilliant and highly fruitful laboratory studies in cytology, genetics and physiological chemistry.

...because the great beauty of embryo development, the bit that human beings find so hard to grasp, is that it is a totally decentralised process...no cell need wait for instructions from authority; every cell can act on its own information and the signals it receives from its neighbours. We do not organise societies that way...Perhaps we should try.

Elms are dying all over the place, it's Dutch elm disease. [...] It came from America on a load of logs, and it's a fungal disease. That makes it sound even more as if it might be possible to do something. The elms are all one elm, they are clones, that's why they are all succumbing. No natural resistance among the population, because no variation. Twins are clones, too. If you looked at an elm tree you'd never think it was part of all the others. You'd see an elm tree. Same when people look at me now: they see a person, not half a set of twins.

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.

Benjamin Franklin wrote little about race, but had a sense of racial loyalty. “[T]he Number of purely white People in the World is proportionably [sic] very small,” he observed. “ . . . I could wish their Numbers were increased.” James Madison, like Jefferson, believed the only solution to the problem of racial friction was to free the slaves and send them away. He proposed that the federal government sell off public lands in order to raise the money to buy the entire slave population and transport it overseas. He favored a Constitutional amendment to establish a colonization society to be run by the President. After two terms in office, Madison served as chief executive of the American Colonization Society, to which he devoted much time and energy. At the inaugural meeting of the society in 1816, Henry Clay described its purpose: to “rid our country of a useless and pernicious, if not dangerous portion of the population.” The following prominent Americans were not merely members but served as officers of the society: Andrew Jackson, Daniel Webster, Stephen Douglas, William Seward, Francis Scott Key, Winfield Scott, and two Chief Justices of the Supreme Court, John Marshall and Roger Taney. All opposed the presence of blacks in the United States and thought expatriation was the only long-term solution. James Monroe was such an ardent champion of colonization that the capital of Liberia is named Monrovia in gratitude for his efforts. As for Roger Taney, as chief justice he wrote in the Dred Scott decision of 1857 what may be the harshest federal government pronouncement on blacks ever written: Negroes were “beings of an inferior order, and altogether unfit to associate with the White race, either in social or political relations; and so far inferior that they have no rights which a White man is bound to respect.” Abraham Lincoln considered blacks to be—in his words—“a troublesome presence” in the United States. During the Lincoln-Douglas debates he expressed himself unambiguously: “I am not nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people; and I will say in addition to this that there is a physical difference between the white and black races which I believe will for ever forbid the two races living together on terms of social and political equality.” His opponent, Stephen Douglas, was even more outspoken, and made his position clear in the very first debate: “For one, I am opposed to negro citizenship in any form. I believe that this government was made on the white basis. I believe it was made by white men for the benefit of white men and their posterity forever, and I am in favor of confining the citizenship to white men—men of European birth and European descent, instead of conferring it upon negroes and Indians, and other inferior races.

Bhramari Om Chanting or Humming Om chanting sends positive messages to the brain and the cells in our body and can actually reprogram our health and behavior.

Eventually, her designed genetic material will be implanted into my egg, which first would have had my genetic material removed. Then my mother could become my baby. And someday, when I get old, I can become her baby. Then she will be mine, and I will be hers.

Except for the rare cases of plastid inheritance, the inheritance of all known cofactors can be sufficiently accounted for by the presence of genes in the chromosomes. In a word the cytoplasm may be ignored genetically.

First Law In every animal which has not passed the limit of its development, a more frequent and continuous use of any organ gradually strengthens, develops and enlarges that organ, and gives it a power proportional to the length of time it has been so used; while the permanent disuse of any organ imperceptibly weakens and deteriorates it, and progressively diminishes its functional capacity, until it finally disappears. Second Law All the acquisitions or losses wrought by nature on individuals, through the influence of the environment in which their race has long been placed, and hence through the influence of the predominant use or permanent disuse of any organ; all these are preserved by reproduction to the new individuals which arise, provided that the acquired modifications are common to both sexes, or at least to the individuals which produce the young.

Don't be ashamed or proud of your genetics,for you have no contribution towards it.

Enlightenment is making every cell, gene and DNA as the radiator of peace and harmony.

Genetically we're just the third species of chimp, a physically weak but social animal. It was in our interests to communicate complex ideas so we could cooperate to hunt big, dangerous prey animals. I think as soon as humans developed language with grammar that allowed for abstract thought, we were set on a whole new evolutionary path, made by and for the spread of ideas instead of genes.

Genetics, accidents of birth or events in early childhood have left criminals' brains and bodies with measurable flaws predisposing them to committing assault, murder and other antisocial acts. .... Many offenders also have impairments in their autonomic nervous system, the system responsible for the edgy, nervous feeling that can come with emotional arousal. This leads to a fearless, risk-taking personality, perhaps to compensate for chronic under-arousal. Many convicted criminals, like the Unabomber, have slow heartbeats. It also gives them lower heart rates, which explains why heart rate is such a good predictor of criminal tendencies. The Unabomber, Ted Kaczynski, for example, had a resting heart rate of just 54 beats per minute, which put him in the bottom 3 per cent of the population.

Genes do not make an individual homosexual. They play their part, but so does the rest of the universe.

Genes do not make you, any more than brain chemistry makes you hungry, food makes you breathe, breathing makes you die.

Geneticists are a group of mathematicians who have taken over the Neanderthal Paleontology Guild. They call the shots now.

Genetics determine whether we get fuck-all or fuck; whether the party doors are opened or closed in our faces.

If, as the dowager had said, we are nothing but gene carriers, why do so many of us have to lead such strangely shaped lives? Wouldn’t our genetic purpose—to transmit DNA—be served just as well if we lived simple lives, not bothering our heads with a lot of extraneous thoughts, devoted entirely to preserving life and procreating? Did it benefit the genes in any way for us to lead such intricately warped, even bizarre, lives?

If there's any interaction between genes and languages, it is often languages that influence genes, since linguistic differences between populations lessen the chance of genetic exchange between them.

If the history of the last century taught us the dangers of empowering governments to determine genetic “fitness” (i.e., which person fits within the triangle, and who lives outside it), then the question that confronts our current era is what happens when this power devolves to the individual. It is a question that requires us to balance the desires of the individual— to carve out a life of happiness and achievement, without undue suffering— with the desires of a society that, in the short term, may be interested only in driving down the burden of disease and the expense of disability. And operating silently in the background is a third set of actors: our genes themselves, which reproduce and create new variants oblivious of our desires and compulsions— but, either directly or indirectly, acutely or obliquely, influence our desires and compulsions. Speaking at the Sorbonne in 1975, the cultural historian Michel Foucault once proposed that “a technology of abnormal individuals appears precisely when a regular network of knowledge and power has been established.” Foucault was thinking about a “regular network” of humans. But it could just as easily be a network of genes.

If we are made in his image. How will that change in this next stage in our evolution? Where we have cloning of individuals and gene manipulation to enhance ourselves. Are we changing what that image is?

If we define "beauty" as having blue eyes (and only blue eyes), then we will, indeed, find a "gene for beauty." If we define "intelligence" as the performance on only one kind of test, then we will, indeed, find a "gene for intelligence." The genome is only a mirror for the breadth or narrowness of human imagination.

If you are living in the electrified wireless west, then you are living a very abnormal lifestyle that your genetics has no adaptation to.

If you think being descended from apes is bad for your self esteem, then get used to the idea that you are also descended from viruses.

I have English genetics that reside in the USA and have worked close to Space.

I have had my mother's wing of my genetic ancestry analyzed by the National Geographic tracing service and there it all is: the arrow moving northward from the African savannah, skirting the Mediterranean by way of the Levant, and passing through Eastern and Central Europe before crossing to the British Isles. And all of this knowable by an analysis of the cells on the inside of my mouth. I almost prefer the more rambling and indirect and journalistic investigation, which seems somehow less… deterministic.

I know genes are a big deal, son, but they're not the be-all and end-all." Rob slowed to a halt at the lights, wishing the dickhead behind would back off. "If they were, you'd be in a seafood salad and I'd be in prison.

Illness might progressively vanish so might identity. Grief might be diminished, but so might tenderness. Traumas might be erased but so might history. Infirmities might disappear, but so might vulnerability. Chance would become mitigated, but so, inevitably, would choice.

In all racial groups, students from wealthy households tend to score better than those who are poor, but income does not explain group differences. A study by McKinsey and Company found that white fourth graders living in poverty scored higher—by the equivalent of about half-a-year’s instruction—than black fourth graders who were not poor. These differences increase in high school. On the 2009 math and verbal SAT tests, whites from families with incomes of less than $20,000 not only had an average combined score that was 117 points (out of 1600) higher than the average for all blacks, they even outscored by 12 points blacks who came from families with incomes of $160,000 to $200,000. Educators and legislators have not ignored the problem. The race gap in achievement is such a preoccupation that in 2007, 4,000 educators and experts attended an “Achievement Gap Summit” in Sacramento. They took part in no fewer than 125 panels on ways to help blacks and Hispanics do as well as whites and Asians. Overwhelming majorities in Congress passed the No Child Left Behind Act in 2002 to improve student performance and bridge achievement gaps. The government budgeted $24.4 billion for the program for fiscal year 2007, and its requirements for “Adequate Yearly Progress” have forced change on many schools. This is only the latest effort in more than 25 years of federal involvement. The result? In 2009, Chester E. Finn, Jr., a former education official in the Reagan administration, put it this way: “This is a nearly unrelenting tale of woe and disappointment. If there’s any good news here, I can’t find it.

If these d'Herelle bodies were really genes, fundamentally like our chromosome genes, they would give us an utterly new angle from which to attack the gene problem. They are filterable, to some extent isolable, can be handled in test-tubes, and their properties, as shown by their effects on the bacteria, can then be studied after treatment. It would be very rash to call these bodies genes, and yet at present we must confess that there is no distinction known between the genes and them. Hence we can not categorically deny that perhaps we may be able to grind genes in a mortar and cook them in a beaker after all. Must we geneticists become bacteriologists, physiological chemists and physicists, simultaneously with being zoologists and botanists? Let us hope so.

In the world of wild naturalism, there is nothing greater or higher than mortal survival tactics. Everything we do, we do as mortal beings with an unknowable date of death stuck on our head, or to be specific in the genetic clock.

I think part of the reason escapism is a predominate aspect of American arts—especially cinema—is because that’s what’s in our DNA. Our ancestors came here to avoid whatever was happening where they were originally from. Escapism is literally in our genes.
