Have you ever had a weird and strong feeling that programming is a godlike kind of work? Just as the Lord created our world and the entire Universe based on molecular techniques such as DNA coding, software developers create a digital world based on IT coding.

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 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.

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

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.

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.

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.

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.

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.

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.

In every cell in every body in every living thing, strings of words make sentences, meanings locked together

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.

It is true that humans have physical differences, and some of those differences are spread geographically across the planet. But clinging to old notions about race won't help us understand the nature of those differences—both the ones we can see and the ones we can't.

It is common to assume that multi-racialism is inevitable, and that racial identity will disappear as races mix. Americans prefer to think that the “tragic mulatto,” welcome in neither community, was either a myth or a reflection of outmoded racist thinking. Research suggests things may not be so simple. A 2003 study of 90,000 middle-school and high-school students found that black/white mixed-race children had more health and psychological problems than children who were either black or white. They were more likely to be depressed, sleep badly, skip school, smoke, drink, consider suicide, and have sex. White/Asian children showed similar symptoms. The principal author concluded that the cause was “the struggle with identity formation, leading to lack of self-esteem, social isolation and problems of family dynamics in biracial households.” The authors of a 2008 study reached the same conclusion: “When it comes to engaging in risky/anti-social adolescent behavior, however, mixed race adolescents are stark outliers compared to both blacks and whites. . . . Mixed race adolescents—not having a natural peer group—need to engage in more risky behaviors to be accepted.” A study of white/Asian children found that they were twice as likely as mono-racial children—34 percent vs. 17 percent—to suffer from psychological disorders such as anxiety, depression or drug abuse. Yoonsun Choi of the University of Chicago found that in Seattle middle schools, a clear racial identity seemed to protect against certain problems. Bi-racial children were the group most likely to smoke, take drugs, have been in fights, hurt someone badly, or carry a gun. Prof. Choi believes mixed-race children suffer because no racial group accepts them. “There is some indication that a strong ethnic identity helps protect kids from these [undesirable] behaviors,” she said.

It is true that humans have physical differences, and some of those differences are spread geographically across the plant. But clinging to old notions about race won't help us understand the nature of those differences—both the ones we can see and the ones we can't.

It’s truly interesting to observe how genetics works in families, and what a huge lottery it is to inherit some of our relatives’ appearance features.

It should be clear by now that whatever Americans say about diversity, it is not a strength. If it were a strength, Americans would practice it spontaneously. It would not require “diversity management” or anti-discrimination laws. Nor would it require constant reminders of how wonderful it is. It takes no exhortations for us to appreciate things that are truly desirable: indoor plumbing, vacations, modern medicine, friendship, or cheaper gasoline. [W]hen they are free to do so, most people avoid diversity. The scientific evidence suggests why: Human beings appear to have deeply-rooted tribal instincts. They seem to prefer to live in homogeneous communities rather than endure the tension and conflict that arise from differences. If the goal of building a diverse society conflicts with some aspect of our nature, it will be very difficult to achieve. As Horace wrote in the Epistles, “Though you drive Nature out with a pitchfork, she will ever find her way back.” Some intellectuals and bohemians profess to enjoy diversity, but they appear to be a minority. Why do we insist that diversity is a strength when it is not? In the 1950s and 1960s, when segregation was being dismantled, many people believed full integration would be achieved within a generation. At that time, there were few Hispanics or Asians but with a population of blacks and whites, the United States could be described as “diverse.” It seemed vastly more forward-looking to think of this as an advantage to be cultivated rather than a weakness to be endured. Our country also seemed to be embarking on a morally superior course. Human history is the history of warfare—between nations, tribes, and religions —and many Americans believed that reconciliation between blacks and whites would lead to a new era of inclusiveness for all peoples of the world. After the immigration reforms of 1965 opened the United States to large numbers of non- Europeans, our country became more diverse than anyone in the 1950s would have imagined. Diversity often led to conflict, but it would have been a repudiation of the civil rights movement to conclude that diversity was a weakness. Americans are proud of their country and do not like to think it may have made a serious mistake. As examples of ethnic and racial tension continued to accumulate, and as the civil rights vision of effortless integration faded, there were strong ideological and even patriotic reasons to downplay or deny what was happening, or at least to hope that exhortations to “celebrate diversity” would turn what was proving to be a problem into an advantage. To criticize diversity raises the intolerable possibility that the United States has been acting on mistaken assumptions for half a century. To talk glowingly about diversity therefore became a form of cheerleading for America. It even became common to say that diversity was our greatest strength—something that would have astonished any American from the colonial era through the 1950s. There is so much emotional capital invested in the civil-rights-era goals of racial equality and harmony that virtually any critique of its assumptions is intolerable. To point out the obvious— that diversity brings conflict—is to question sacred assumptions about the ultimate insignificance of race. Nations are at their most sensitive and irrational where they are weakest. It is precisely because it is so easy to point out the weaknesses of diversity that any attempt to do so must be countered, not by specifying diversity’s strengths—which no one can do—but with accusations of racism.

Meditation works in many layers. It works in our genes, in our DNA

More than any other single trait, it is the apple’s genetic variability—its ineluctable wildness—that accounts for its ability to make itself at home in places as different from one another as New England and New Zealand, Kazakhstan and California. Wherever the apple tree goes, its offspring propose so many different variations on what it means to be an apple—at least five per apple, several thousand per tree—that a couple of these novelties are almost bound to have whatever qualities it takes to prosper in the tree’s adopted home.

Murder and suicide aren't genetic,' Julia said, scoffing sandwiches in the Black Swan in Helmsley after their visit to Rievaulx Terraces. 'Nathan isn't predisposed to tragedy.' Jackson wasn't so sure about that but he kept that thought to himself.

My dad will win, I silently countered, even as I smiled sweetly. I couldn’t wait to spike the ball right through her block, no matter how tall she was. In health class we’d learned that if Barbie were human, she’d be six feet tall and weigh one hundred pounds, and Gisele seemed pretty close to those dimensions. By contrast, my doll representation would be more like Barbie’s Fat Mexican-American Republican sidekick.

Now the leatherback turtle overcame the heat issue via a simple, but evolutionarily impossible solution; it is the only reptile that possesses fatty insulation known as brown adipose tissue, and the only reptile that regulates a high body temperature. This brown adipose tissue is the expression of the UCP1 gene, and, aside from the leatherbacks, is found only in mammals, amphibians, and fishes. Not one other reptile has UCP1.

Our highest contribution is making this world peaceful and happy. That comes when we can radiate peace and harmony from every cell, gene and DNA of our body.

Signal transduction science recognizes that the fate and behavior of an organism is directly linked to its perception of the environment.

The family trees of all of us, of whatever origin or trait, must meet and merge into one genetic tree of all humanity by the time they have spread into our ancestries for about 50 generations.

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!

The Lutz heck that emerges from his writings and actions drifted like a weather vane: charming when need be, cold-blooded when need be, tigerish or endearing, depending on his goal. Still, it is surprising that Heck the zoologist chose to ignore the accepted theory of hybrid vigor: that interbreeding strengthens a bloodline. He must have known that mongrels enjoy better immune systems and have more tricks up their genetic sleeves, while in a closely knit species, however "perfect," any illness that kills one animal threatens to wipe out all the others, which is why zoos keep careful studbooks of endangered animals such as cheetahs and forest bison and try to mate them advantageously. In any case, in the distant past, long before anyone was recognizably Aryan, our ancestors shared the world with other flavors of hominids, and interbreeding among neighbors often took place, producing hardier, nastier offspring who thrived. All present-day humans descend from that robust, talkative mix, specifically from a genetic bottleneck of only about one hundred individuals. A 2006 study of mitochondrial DNA tracks Ashkenazi Jews (about 92 percent of the world’s Jews in 1931) back to four women, who migrated from the Near East to Italy in the second and third centuries. All of humanity can be traced back to the gene pool of one person, some say to a man, some a woman. It’s hard to imagine our fate being as iffy as that, be we are natural wonders.

The more you treat your body and the cells as intelligent being the more you will be sharp, quick, competent, and fulfilled.

The problem with racial discrimination, though, is not the inference of a person's race from their genetic characteristics. It is quite the opposite: it is the inference of a person's characteristics from their race. The question is not, can you, given an individual's skin color, hair texture, or language, infer something about their ancestry or origin. That is a question of biological systematics -- of lineage, taxonomy, of racial geography, of biological discrimination. Of course you can -- and genomics as vastly refined that inference. You can scan any individual genome and infer rather deep insights about a person's ancestry, or place of origin. But the vastly more controversial question is the converse: Given a racial identity -- African or Asian, say -- can you infer anything about an individual's characteristics: not just skin or hair color, but more complex features, such as intelligence, habits, personality, and aptitude? /I/ Genes can certainly tell us about race, but can race tell us anything about genes? /i/ To answer this question, we need to measure how genetic variation is distributed across various racial categories. Is there more diversity _within_ races or _between_ races? Does knowing that someone is of African versus European descent, say, allow us to refine our understanding of their genetic traits, or their personal, physical, or intellectual attributes in a meaningful manner? Or is there so much variation within Africans and Europeans that _intraracial_ diversity dominates the comparison, thereby making the category "African" or "European" moot? We now know precise and quantitative answers to these questions. A number of studies have tried to quantify the level of genetic diversity of the human genome. The most recent estimates suggest that the vast proportion of genetic diversity (85 to 90 percent) occurs _within_ so-called races (i.e., within Asians or Africans) and only a minor proportion (7 percent) within racial groups (the geneticist Richard Lewontin had estimated a similar distribution as early as 1972). Some genes certainly vary sharply between racial or ethnic groups -- sickle-cell anemia is an Afro-Caribbean and Indian disease, and Tay-Sachs disease has a much higher frequency in Ashkenazi Jews -- but for the most part, the genetic diversity within any racial group dominates the diversity between racial groups -- not marginally, but by an enormous amount. The degree of interracial variability makes "race" a poor surrogate for nearly any feature: in a genetic sense, an African man from Nigria is so "different" from another man from Namibia that it makes little sense to lump them into the same category.

There were three things sought by invaders who crossed oceans to discover America. Those were gold, gospel, glory. There are four things sought by aliens who crossed heavens to discover planet earth. Those are gold, gospel, glory, gene.

TP53 seems to encode the greater good, like a suicide pill in the mouth of a soldier that dissolves only when it detects evidence that he is about to mutiny.

Trust in the familiar seems to be matched by wariness of the unfamiliar. Jennifer Richeson of Northwestern University has conducted experiments in which white subjects had to interact in some way with a white or a black man before taking a mental test. Those who dealt with the black man got lower scores on the test, and their brain scans showed what Prof. Richeson called “heightened activity in areas of the brain associated with regulating our thoughts and emotions.” She interpreted this to mean that white subjects were struggling with the “awkwardness” or “exhaustion” of dealing with a black man, and that this interfered with their ability to take the mental test. Researchers at Harvard and New York University had white and black subjects look repeatedly at a series of photographs of black and white faces, all with neutral expressions. Every time the subjects looked at one particular black face and one particular white face they got a mild electric shock. Lie detector-type devices showed that subjects would sweat—a typical stress reaction—when they saw the two faces they associated with the shocks. The researchers showed the photo series several times again, but without the shocks. White subjects quickly stopped sweating when they saw the white face formerly associated with the shock, but continued to sweat when they saw the black face. Black subjects had the opposite reaction, continuing to sweat when they saw the white but not the black face. Mahzarin Banaji, the study’s leader, concluded that this was a sign of natural human wariness of unfamiliar groups.

We are often given pills or fluids to help remedy illness, yet little has been taught to us about the power of smell to do the exact same thing. It is known that the scent of fresh rosemary increases memory, but this cure for memory loss is not divulged by doctors to help the elderly. I also know that the most effective use of the blue lotus flower is not from its dilution with wine or tea – but from its scent. To really maximize the positive effects of the blue lily (or the pink lotus), it must be sniffed within minutes of plucking. This is why it is frequently shown being sniffed by my ancient ancestors on the walls of temples and on papyrus. Even countries across the Orient share the same imagery. The sacred lotus not only creates a relaxing sensation of euphoria, and increases vibrations of the heart, but also triggers genetic memory - and good memory with an awakened heart ushers wisdom.

We both lacked the same thing in our childhoods - the love of a father... We both sought to fill that lack in our adult lives with family and love, as everyone does, but also with thrills and sometimes periods of recklessness. Luckily, I have always come back from my recklessness. Tommy Darling did not.

We live in an exciting time. We now know more than ever about our biology and about our history, allowing us to peer into the future with greater clarity than has previously been possible. But at the same time, the changes we are undergoing, brought about by our own advances in technology, medicine, transportation-- and by the growing impact we are having on the world around us-- mean that we live in a time in which the future looks increasingly less like the past. We have become an odd species, indeed, but our story is not yet over. Like all species, Homo sapiens continues to evolve, so there is one thing we can say with certainty: the people of tomorrow will not be the same as the people of today.

What are the implications of ethnic identity for multi-racial and multi-ethnic societies? Tatu Vanhanen of the University of Tampere, Finland, has probably researched the effects of ethnic diversity more systematically than anyone else. In a massive, book-length study, he measured ethnic diversity and levels of conflict in 148 countries, and found correlations in the 0.5 to 0.9 range for the two variables, depending on how the variables were defined and measured. Homogeneous countries like Japan and Iceland show very low levels of conflict, while highly diverse countries like Lebanon and Sudan are wracked with strife. Prof. Vanhanen found tension in all multi-ethnic societies: “Interest conflicts between ethnic groups are inevitable because ethnic groups are genetic kinship groups and because the struggle for existence concerns the survival of our own genes through our own and our relatives’ descendants.” Prof. Vanhanen also found that economic and political institutions make no difference; wealthy, democratic countries suffer from sectarian strife as much as poor, authoritarian ones: “Ethnic nepotism belongs to human nature and . . . it is independent from the level of socioeconomic development (modernization) and also from the degree of democratization.” Others have argued that democracy is particularly vulnerable to ethnic tensions while authoritarian regimes like Saddam Hussein’s Iraq or Tito’s Yugoslavia can give the impression of holding it in check. One expert writing in Foreign Affairs explained that for democracy to work “the party or group that loses has to trust the new majority and believe that its basic interests will still be protected and that there is nothing to fear from a change in power.” He wrote that this was much less likely when opposing parties represent different races or ethnicities. The United Nations found that from 1989 to 1992 there were 82 conflicts that had resulted in at least 1,000 deaths each. Of these, no fewer than 79, or 96 percent, were ethnic or religious conflicts that took place within the borders of recognized states. Only three were cross-border conflicts. Wars between nations are usually ethnic conflicts as well. Internal ethnic conflict has very serious consequences. As J. Philippe Rushton has argued, “The politics of ethnic identity are increasingly replacing the politics of class as the major threat to the stability of nations.” One must question the wisdom of then-president Bill Clinton’s explanation for the 1999 NATO bombing of Serbia: “[T]he principle we and our allies have been fighting for in the Balkans is the principle of multi-ethnic, tolerant, inclusive democracy. We have been fighting against the idea that statehood must be based entirely on ethnicity.” That same year, the American supreme commander of NATO, Wesley Clark, was even more direct: “There is no place in modern Europe for ethnically pure states. That’s a 19th century idea and we are trying to transition into the 21st century, and we are going to do it with multi-ethnic states.

When we die, we live on in our children.

You can inherit good genes, not greatness.

You inherit your environment just as much as your genes.

All illnesses have some heredity contribution. It's been said that genetics loads the gun and environment pulls the trigger.

I was drawn to horses as if they were magnets. It was in my blood. I must have inherited from my grandfather a genetic proclivity toward the equine species. Perhaps there's a quirk in the DNA that makes horse people different from everyone else, that instantly divides humanity into those who love horses and the others, who simply don't know.

Longevity-and sanity. Eccentric old ladies on Harleys I can deal with.

Man with all his noble qualities still bears in his bodily frame the indelible stamp of his lowly origin.

Many kinds of animal behavior can be explained by genetic similarity theory. Animals have a preference for close kin, and study after study has shown that they have a remarkable ability to tell kin from strangers. Frogs lay eggs in bunches, but they can be separated and left to hatch individually. When tadpoles are then put into a tank, brothers and sisters somehow recognize each other and cluster together rather than mix with tadpoles from different mothers. Female Belding’s ground squirrels may mate with more than one male before they give birth, so a litter can be a mix of full siblings and half siblings. Like tadpoles, they can tell each other apart. Full siblings cooperate more with each other than with half-siblings, fight less, and are less likely to run each other out of the territory when they grow up. Even bees know who their relatives are. In one experiment, bees were bred for 14 different degrees of relatedness—sisters, cousins, second cousins, etc.—to bees in a particular hive. When the bees were then released near the hive, guard bees had to decide which ones to let in. They distinguished between degrees of kinship with almost perfect accuracy, letting in the closest relatives and chasing away more distant kin. The correlation between relatedness and likelihood of being admitted was a remarkable 0.93. Ants are famous for cooperation and willingness to sacrifice for the colony. This is due to a quirk in ant reproduction that means worker ants are 70 percent genetically identical to each other. But even among ants, there can be greater or less genetic diversity, and the most closely related groups of ants appear to cooperate best. Linepithema humile is a tiny ant that originated in Argentina but migrated to the United States. Many ants died during the trip, and the species lost much of its genetic diversity. This made the northern branch of Linepithema humile more cooperative than the one left in Argentina, where different colonies quarrel and compete with each other. This new level of cooperation has helped the invaders link nests into supercolonies and overwhelm local species of ants. American entomologists want to protect American ants by introducing genetic diversity so as to make the newcomers more quarrelsome. Even plants cooperate with close kin and compete with strangers. Normally, when two plants are put in the same pot, they grow bigger root systems, trying to crowd each other out and get the most nutrients. A wild flower called the Sea Rocket, which grows on beaches, does not do that if the two plants come from the same “mother” plant. They recognize each others’ root secretions and avoid wasteful competition.

Many theories have been advanced to explain racial gaps in performance, of which these are the most common: black and Hispanic schools do not get enough money, their classes are too big, students are segregated from whites, minorities do not have enough teachers of their own race. Each of these explanations has been thoroughly investigated. Urban schools, where non-whites are concentrated, often get more money than suburban white schools, so blacks and Hispanics are not short-changed in budget or class size. Teacher race has no detectable effect on learning (Asians, for example, outperform whites regardless of who teaches them), nor do whites in the classroom raise or lower the scores of students of other races. Money is not the problem. From the early 1970s to the 2006-2007 school year per-pupil spending more than doubled in real terms. The Cato Institute calculates that when capital costs are included, the Los Angeles School District spends more than $25,000 per student per year, and the District of Columbia spends more than $28,000. Neither district gets good results. Demographic change can become a vicious cycle: As more minorities and immigrants enter a school system average achievement falls. More money and effort is devoted to these groups, squeezing gifted programs, music and art, and advanced placement courses. The better-performing students leave, and standards fall further.
