The Problem

"An ounce of algebra is worth a ton of verbal argument" J.B.S. Haldane (as quoted by John Maynard Smith)
The need for evolutionary game theory in biology started with a problem. The problem was how to explain ritualized animal behaviour in a conflict situation; "why are animals so "gentlemanly or ladylike" in contests for resources?" This was a problem that leading ethologists Niko Tinbergen and Konrad Lorenz were trying to address. Tinbergen proposed that such behaviour exists for the benefit of the species. Maynard Smith couldn't see this reasoning matched with Darwinian thought as he understood it, where selection occurs at an individual level and therefore defections to self-interest are rewarded while seeking the common good is not. Maynard Smith, a former engineer and highly competent mathematician, turned to game theory to answer the question. The suggestion that game theory might solve the problem was made by George Price even though some unsuccessfully applied efforts by Richard Lewontin at using game theory had failed. Maynard Smith’s way of applying this mathematics proved to be a far more realistic model, and came to be a major mathematical contribution in the field of theoretical biology.

Famous quotes containing the words the problem and/or problem:
“In a town-meeting, the great secret of political science was uncovered, and the problem solved, how to give every individual his fair weight in the government, without any disorder from numbers. In a town-meeting, the roots of society were reached. Here the rich gave counsel, but the poor also; and moreover, the just and the unjust.”
—Ralph Waldo Emerson (1803–1882)
“The disesteem into which moralists have fallen is due at bottom to their failure to see that in an age like this one the function of the moralist is not to exhort men to be good but to elucidate what the good is. The problem of sanctions is secondary.”
—Walter Lippmann (1889–1974)
“If a problem is insoluble, it is Necessity. Leave it alone.”
—Mason Cooley (b. 1927)
