So what we can answer [as geneticists] is questions about biology, about biological ancestry. But to make any sense of that historically we have to contextualize it - the archaeology, the linguistic pattern, even the climatology.

The basic science is not physics or mathematics but biology -- the study of life. We must learn to think both logically and bio-logically.

The Department of Cell Biology at Johns Hopkins was founded and directed by Tom Pollard, an engaging young scientist with remarkable energy and enthusiasm.

Technology evolves faster than people do, faster than biology does.

The great merit of Stephen Gould's account of the disastrous history of phychometrics is that he shifts the argument from a sterile contest between environmentalists and hereditarians and turns it into an argument between those who are impressed with what our biology stops us doing and those who are impressed with what it allows us to do.

The major thing is to view biology as an information science.

The biology of purpose keeps my nose above the surface.

There is no true understanding of Biology without Chemistry. And there's no true understanding of Chemistry without Physics.

The kitchen's a laboratory, and everything that happens there has to do with science. It's biology, chemistry, physics. Yes, there's history. Yes, there's artistry. Yes, to all of that. But what happened there, what actually happens to the food is all science.

There are a whole other range of sciences that must deal with the narrative reconstruction of the inordinately complex events of history that can occur but once in their detailed glory. And for those kinds of sciences, be it cosmology, or evolutionary biology, or geology, or palaeontology, the experimental methods, simplification, quantification, prediction and repetition of the experimental sciences don't always work. You have to go with the narrative, the descriptive methods of what? Of historians.

There is more to biology than rats, Drosophila, Caenorhabditis, and E. coli.

Ubiquity must never be mistaken for biology.

The supersession of dualism in biology begins to occur in this science at the moment when the ‘time’ factor is taken into consideration.

Until we recognize the essential role of biology, our attempts to truly unify the universe will remain a train to nowhere.

The fact of evolution is the backbone of biology, and biology is thus in the peculiar position of being a science founded on an improved theory, is it then a science or faith?

We argue with our biology, and the result of that argument is civilization.

We didn't stay in the caves. We haven't stayed on the planet. With biotechnology, gene sequencing, we are not going to even stay within the limitations of biology.

We can truly see that consciousness is operating creatively even in biology, even in the evolution of species.

We know from biology that new forms of organisms simulate their primitive form as closely as possible at first, even though obliged to exist under changed internal and external conditions.

"Tiger is a natural kind" and "Tiger is a historical particular" are incompatible with each other, and evolutionary biology provides a reason for favoring the latter over the former.

We reject creationism because there is no evidence to support it. By contrast, the notion that biology is at least partially the basis of gender is an empirically supportable, and even well-supported, proposition. The gender scholars reject it on ideological, not evidentiary, grounds.

We must [it has been arued] go beyond reductionism to a holistic recognition that biology and culture interpenetrate in an inextricable manner.

We're going to die, and that makes us the lucky ones.

What an odd time to be a fundamentalist about adaptation and natural selection - when each major subdiscipline of evolutionary biology has been discovering other mechanisms as adjuncts to selection's centrality.

What was that?" Galladon demanded. "I think I just destroyed the biology section" Raoden replied with wonder.

When you free women so they can choose to have or not to have, or to conceive - that's something that, for millennia, women couldn't do. Biology was, in many ways, destiny. We wouldn't be talking about gender if women could not control their pregnancies.

When you tell filthy jokes as if they were all really serious, and happening all in the life of one family, it becomes a farcical situation. Imagine if you had a script that was imposed on your life - we all do in a certain way, from society, or family, the need to make money, biology, death. But you will have a certain latitude, or freedom, to read the script in your own way.

When you choose to view your stress response as helpful, you create the biology of courage.

When you have really solid biology and medical science at the core of an issue, it makes it much easier to identify what potential solutions may be.

Addiction is when natural biological imperatives, like the need for food, sex, relaxation or status, become prioritised to the point of destructiveness. It is exacerbated by a culture that understandably exploits this mechanic as it's a damn good way to sell Mars bars and Toyotas.

Yes, there's genetics. Yes, there are chromosomes. Yes, there's biology. Yes, there are environment, sociology, parenting, economics, class, and all of that. But there is something else, as well.

You are part of a complex social network that changes your biology with every interaction, and which your actions can change.

You can't teach biology with a bottle containing dead animals and organisms.

About 13.5 billion years ago, matter, energy, time and space came into being in what is known as the Big Bang. The story of these fundamental features of our universe is called physics. About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then combined into molecules. The story of atoms, molecules and their interactions is called chemistry. About 3.8. billion years ago, on a planet called Earth, certain molecules combined to form particularly large and intricate structures called organisms. The story of organisms is called biology. About 70,000 years ago, organisms belonging to the species Homo sapiens started to form even more elaborate structures called cultures. The subsequent development of these human cultures is called history.

A corrupt corporate government employs blatantly corrupt scientists.

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.

Lister saw the vast importance of the discoveries of Pasteur. He saw it because he was watching on the heights, and he was watching there alone.

A lifetime can be spent in a Magellanic voyage around the trunk of a single tree.

All organisms vary. It is in the highest degree improbable that any given variety should have exactly the same relations to surrounding conditions as the parent stock. In that case it is either better fitted (when the variation may be called useful), or worse fitted, to cope with them. If better, it will tend to supplant the parent stock; if worse, it will tend to be extinguished by the parent stock. If (as is hardly conceivable) the new variety is so perfectly adapted to the conditions that no improvement upon it is possible,—it will persist, because, though it does not cease to vary, the varieties will be inferior to itself. If, as is more probable, the new variety is by no means perfectly adapted to its conditions, but only fairly well adapted to them, it will persist, so long as none of the varieties which it throws off are better adapted than itself. On the other hand, as soon as it varies in a useful way, i.e. when the variation is such as to adapt it more perfectly to its conditions, the fresh variety will tend to supplant the former.

All disciplines of science are built on the causality of the relationships governing related events. Yet the theory of evolution is built upon the idea of accidental changes that resulted in complex living systems. I was unable to comprehend how the notion that an infinite number of random accidents systematically happened to produce living species, and kept improving these beings, is justified.

...all flourishing is mutual.

All our sentiments - religious, romantic or any other - are born in the neurons.

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.

All answers lie in the neurons.

All species on earth are related to one another like cousins and distant kin in a vast family tree of life.

All the more recent work on alkaptonuria has... strengthened the belief that the homogentisic acid excreted is derived from tyrosine, but why alkaptonuric individuals pass the benzene ring of their tyrosine unbroken and how and where the peculiar chemical change from tyrosine to homogentisic acid is brought about, remain unsolved problems.

All the so-called philosophical notion of “love without attachment” or “detached love” are biologically non-existent on this planet. We humans are biologically designed through millions of years of evolution to grow attachment. Love cannot survive without attachment.

Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it... The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game. Is it surprising that, like the person who has just made a million at the casino, we should feel strange and a little unreal?

A multitude of harlequin lifeforms bobbed and twirled and played in the depths of the Atlantic. Pink cucumbers with thorny backs. Algae. Starfish. Annelids with simple brains and a hundred toes. Sponges—like yellow, swollen hands—sucked in water and pushed out oxygen. Most amusing were the mysterious buggers who had no likeness on the previous earth; tiny beasts with exotic exoskeletons engraved with deep grid-like patterns, snails with horns, and slithering plants that looked like magenta weeping willows.

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.
