John Burdon Sanderson Haldane FRS (November 5, 1892 – December 1, 1964), who normally used "J.B.S." as a first name, was a British geneticist and evolutionary biologist. He was one of the founders (along with Ronald Fisher and Sewall Wright) of population genetics.

[edit] Biography

Haldane was born in Edinburgh, to physiologist John Scott Haldane and Louisa Kathleen Haldane, and descended from Scottish aristocrats (see Haldane family). His younger sister Naomi Mitchison became a writer. Haldane was educated at Dragon School, Eton College (which he hated) and at New College, Oxford.

During the First World War, he served with the Black Watch in France and Iraq. He was initially Bombing Officer for the 3rd Battalion before becoming a Trench Mortar Officer in the 1st. While in the army, he became a socialist, writing "If I live to see an England in which socialism has made the occupation of a grocer as honourable as that of a soldier, I shall die happy".

Between 1919 and 1922 he was a fellow of New College, then moved to Cambridge University until 1932. He then moved to University College, London where he spent most of his academic career. In the late 1950s he moved to India at the invitation of P. C. Mahalanobis. The move was ostensibly a protest against the Suez War, but had been a possibility for some while. He became an Indian citizen.

In 1923 in a talk given in Cambridge, Haldane forseeing the exhaustion of coal for power generation in Britain, proposed a network of hydrogen-generating windmills. This is the first proposal of the hydrogen-based renewable energy economy.

In 1924 Haldane met Charlotte Burghes (nee Franken) and the two later married. To do so Charlotte divorced her husband Jack Burghes, causing some controversy.

In 1925, GE Briggs and Haldane derived a new interpretation of the enzyme kinetics law described by Victor Henri in 1903, different from the 1913 Michaelis-Menten equation. Leonor Michaelis and Maud Menten assumed that enzyme (catalyst) and substrate (reactant) are in fast equilibrium with their complex, which then dissociates to yield product and free enzyme. The Briggs-Haldane equation was of the same algebraic form, but their derivation is based on the quasi steady state approximation, that is the concentration(s) of intermediate complex(es) do(es) not change. As a result, the microscopic meaning of the "Michaelis Constant" (km) is different. Although commonly referring it as Michaelis-Menten kinetics, most of the current models actually use the Briggs-Haldane derivation.

Haldane made many contributions to human genetics and was one of the three major figures to develop the mathematical theory of population genetics. He is usually regarded as the third of these in importance, after R. A. Fisher and Sewall Wright. His greatest contribution was in a series of papers on "A Mathematical Theory of Natural and Artificial Selection" which was the major series of papers on the mathematical theory of natural selection. It treated many major cases for the first time, showing the direction and rates of changes of gene frequencies. It also pioneered in investigating the interaction of natural selection with mutation and with migration. Haldane's book, The Causes of Evolution (1932), summarized these results, especially in its extensive appendix. This body of work was a major component of what came to be known as the "modern evolutionary synthesis", reestablishing natural selection as the premier mechanism of evolution by explaining it in terms of the mathematical consequences of Mendelian genetics.

Haldane introduced many quantitative approaches in biology such as in his essay On Being the Right Size. His contributions to theoretical population genetics and statistical human genetics included the first methods using maximum likelihood for estimation of human linkage maps, and pioneering methods for estimating human mutation rates. His was the first to calculate the mutational load caused by recurring mutations at a gene locus, and to introduce the idea of a "cost of natural selection".

Haldane was a keen experimenter, willing to expose himself to danger to obtain data. One experiment involving elevated levels of oxygen saturation triggered a fit which resulted in him suffering crushed vertebrae. In his decompression chamber experiments, he and his volunteers suffered perforated eardrums, but, as Haldane stated in What is Life, "the drum generally heals up; and if a hole remains in it, although one is somewhat deaf, one can blow tobacco smoke out of the ear in question, which is a social accomplishment."

He was also a famous science populariser like Isaac Asimov, Stephen Jay Gould, or Richard Dawkins. His essay, 'Daedalus or Science and the Future' (1923), was remarkable in predicting many scientific advances but has been criticized for presenting a too idealistic view of scientific progress.

Haldane was very idealistic, and in his youth was a devoted Communist and author of many articles in The Daily Worker. Events in the Soviet Union, such as the rise of the anti-Mendelian agronomist Trofim Lysenko and the crimes of Stalin, caused him to break with the Communist Party later in life. He joined the Communist party in 1937 but left in 1950, shortly after having toyed with standing for Parliament as a Communist Party candidate. However, his support for the Socialist ideal appears to be a pragmatic one. Writing in 1928, in On Being the Right Size, Haldane doubts whether the Socialist principle could be operated on the scale of the British Empire or the United States (or, implicitly, the Soviet Union): "while nationalization of certain industries is an obvious possibility in the largest of states, I find it no easier to picture a completely socialized British Empire or United States than an elephant turning somersaults or a hippopotamus jumping a hedge."

He is also known for an observation from his essay, On Being the Right Size, which Jane Jacobs and others have since referred to as Haldane's principle. This is that sheer size very often defines what bodily equipment an animal must have: "Insects, being so small, do not have oxygen-carrying bloodstreams. What little oxygen their cells require can be absorbed by simple diffusion of air through their bodies. But being larger means an animal must take on complicated oxygen pumping and distributing systems to reach all the cells." The conceptual metaphor to animal body complexity has been of use in energy economics and secession ideas.

Haldane was a friend of the author Aldous Huxley, and was the basis for the biologist Shearwater in Huxley's novel Antic Hay. Ideas from Haldane's Daedalus, such as ectogenesis (the development of fetuses in artificial wombs), also influenced Huxley's Brave New World.

The most famous of Haldane's many students, John Maynard Smith, shared his mixture of political and scientific interests.

Haldane died on December 1, 1964. He willed that his body be used for study at the Rangaraya Medical College, Kakinada. [1]

“

My body has been used for both purposes during my lifetime and after my death, whether I continue to exist or not, I shall have no further use for it, and desire that it shall be used by others. Its refrigeration, if this is possible, should be a first charge on my estate

”

• Wives: Charlotte Burghes (née Franken), Helen Spurway
• He has an Erdős number of 5.
• He is famous also for the response he gave when a clergyman asked him what attribute of the Creator he found the most remarkable: "An inordinate fondness for beetles".
• Often quoted for saying, "My own suspicion is that the universe is not only queerer than we suppose, but queerer than we can suppose." [2] Haldane is sometimes misquoted as saying, "Not only is the universe stranger than we imagine, it is stranger than we can imagine" which should be attributed to Arthur Stanley Eddington. [3]
