John Burdon Sanderson Haldane ( November 5, 1892 - December 1, 1964) was a geneticist born in Scotland and educated at Eton and Oxford University. He was one of the founders (along with Fisher and Wright) of population genetics.

His famous book, The Causes of Evolution ( 1932), was the first major work 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.

He was also a great science popularizer, and was perhaps the Stephen Jay GouldStephen Jay Gould ( September 10, 1941 May 20, 2002) was a New York-born American paleontologist, an evolutionary biologist and historian of science. He was the most influential and widely-read writer of research-based popular science of his generation. or Richard DawkinsClinton Richard Dawkins FRS (born March 26, 1941), better known as Richard Dawkins is a British zoologist, born in Nairobi, in Kenya. He is currently Charles Simonyi Professor of the Public Understanding of Science at the University of Oxford, and is one of his day.

Haldane was himself a very idealistic man, 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 LysenkoTrofim Denisovich Lysenko ( Russian: ) ( September 29, 1898 November 20, 1976) was a Soviet biologist who, during the 1930s, led a campaign against agricultural genetics now known as Lysenkoism, which lasted until the mid- 1960s in the USSR. Biography Lys and the crimes of Stalin, caused him to break with the Communist Party later in life.

He is also known for an observation from his essay, On Being the Right SizeOn Being the Right Size is a 1928 essay by J. It discusses proportions in the animal world and the essential link between the size of an animal and these systems an animal has for life.

She was born in Scranton, Pennsylvania and now lives in Toronto, Ontario. In 1944 she was married to Robert Hyde Jacobs. She has two sons, James Kedzie, born 1948, and Edward Deck 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 metaphorConceptual metaphor In cognitive linguistics metaphor is defined as understanding one conceptual domain in terms of another conceptual domain, e. one person's life experience versus another's. A conceptual domain is any coherent organization of experience to animal body complexity has been of use in energy economics and secession ideas.

Haldane was friends with 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.

He had many students, the most famous of whom, John Maynard Smith, was perhaps also the one most like himself.

In one of the last speeches of his life, Biological Possibilities for the Human Species of the Next Ten Thousand Years ( 1963), Haldane coined the word " clone", from the Greek word for twig.

Haldane was a very quotable man. Some of the things he said are probably more famous than he is:

• The Creator, if He exists, has a special preference for beetles.. This is referring to the fact that 25% of all known animal species are types of beetle.
• Four stages of acceptance: i) this is worthless nonsense; ii) this is an interesting, but perverse, point of view; iii) this is true, but quite unimportant; iv) I always said so. This is referring to the stages that a scientific theory goes through.
• Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we CAN suppose. Often referred to as "Haldane's Law" (not to be confused with Haldane's rule), this is an explanation for the increasing counterintuitiveness of modern scientific theories.
• Would I lay down my life to save my brother? No, but I would to save two brothers or eight cousins. This is a joke based on the idea of inclusive fitness. Basically, the joke is as you only share 50% of your genes with a brother, and 12.5% with a cousin, you would have to save enough relatives to at least break even.

It is worth mentioning, to those who are keen on books for their own sake, that his most sought-after and valuable publication, as far as collectors are concerned, is the short story My Friend Mr Leakey - which indeed is where the 'queerer than we suppose' quotation can be found in print (though it is likely that JBSH thought this one up beforehand and incorporated it in the story for our amusement).
