Lorenz shared the 1973 Nobel Prize in Physiology or Medicine with Niko Tinbergen and Karl von Frisch. On Lorenz, his co-Nobelists, and the history of ethology, see Richard W. Burkhardt, Jr.,
Patterns of Behavior: Konrad Lorenz, Niko Tinbergen, and the Founding of Ethology
(Chicago: University of Chicago Press, 2005).

Lorenz eventually published his theories on animal fighting in book form in
On Aggression
(London: Methuen, 1966). The assumption of the wide prevalence of nonviolent ritualized combat has since been softened—animals, it seems, escalate conflict more than was previously suspected.

Huxley’s grandson Julian Huxley also espoused a group selectionist argument to explain ritualized combat: See J. S. Huxley, “Ritualization of Behaviour in Animals and Man,”

Maynard Smith later explained that he was aware of the “unbeatable strategy” term in Hamilton’s 1967 paper, but hadn’t registered this as influencing his ideas when formalizing the ESS. “In Haldane’s Footsteps,” 352.

George R. Price, “Extension of Covariance Selection Mathematics,”
Annals of Human Genetics
35 (1972), 485–90. George had recently learned (and acknowledged in this paper) that Alan Robertson had published a covariance selection equation prior and similar to his own in a somewhat obscurely placed article, “A Mathematical Model of the Culling Process in Dairy Cattle,”
Animal Production
8 (1966), 95–108. Robertson, however, a researcher more concerned with breeding practice than evolution, had not added the second, transmission term to his equation, meaning that it was not expansible to multiple levels of selection, which was the whole beauty of George’s approach. A few months after George’s own derivation of the equation, the mathematical biologist Joel E. Cohen, then at the Society of Fellows at Harvard University, independently derived the covariance relationship (again, without its expansible component) in an attempt to determine whether the differential use of legal abortions by people of varying socioeconomic or educational status had a positive or negative selective effect on measured IQ. It was published nine months after George’s
Nature
paper as “Legal Abortions, Socioeconomic Status, and Measured Intelligence in the United States,”
Social Biology
18 (1971), 55–63. Cohen had derived the covariance from what he took to be “an easy consequence” of the formula for the selection differential published by the eminent Edinburgh quantitative geneticist Douglas S. Falconer, and was therefore not all impressed by either his or, when he learned of it, George’s, originality. See, D. S. Falconer, “Genetic Consequences of Selection Pressure,” in
Genetic and Environmental Factors in Human Ability
, ed. J. E. Meade and A. S. Parkes (Edinburgh: Oliver and Boyd, 1966), 219–32. There was a further antecedent to the covariance equation that George was unaware of, once again without the second term: C. C. Li, “Fundamental Theorem of Natural Selection,”
Nature
214 (1967), 505–6. I thank Joel Cohen, now a professor at the Laboratory of Populations at Rockefeller and Columbia Universities, for correspondence about this matter throughout May 2008.

George viewed the genetic polymorphism work as a “digression” from the “Sex and Rapid Evolution” paper he was working on at the time but undertook it nevertheless since he felt it would help him better understand a point involved in the sex paper: George Price letter to John Maynard Smith, April 20, 1972; “Antlers” File, John Maynard Smith Papers, British Library (BLJMSC).

The model used the following probabilities: Probability of serious injury from a single D play = 0. 10. Probability that a “Prober-Retaliator” will probe on the opening move or after opponent has played C = 0. 05. Probability that “Retaliator” or “Prober-Retaliator” will retaliate against a probe (if not injured) by opponent = 1. 0. Payoffs were calculated as follows: Payoff for winning = +60. Payoff for receiving serious injury = -100. Payoff for each D received that does not cause serious injury (a “scratch”) = -2. Payoff for saving time and energy (awarded to each contestant not seriously injured) varied from 0 for a contest of maximum length to +20 for a very short contest.
