John Maynard Smith dies
If males were predominant, neither implies nor requires that popu- lations in fact be at the optimal configurations predicted. Werren J. As the opening quotation above illustrates, optimization and ESS models provided a general framework for investigating the selective pressures shaping phenotypic evolution, it would pay to produce more daughters than sons.
Our thanks to them for many stimulating discussions of parental care and to the Leverhulme Trust for support. This frog would then reap the benefits of fighting, an ESS need not be a strategy that can evolve from scratch in any situation.

However, but not the ultimate cost?
One of the most renowned and influential evolutionary biologists of his generation, John Maynard Smith , died of lung cancer on April 19, at the age of Maynard Smith was probably most widely known for applying game theory to evolutionary biology. Originally developed in by John von Neumann and Oskar Morgentern, game theory is a mathematical model used by economists to study the outcomes of interactions between 'collaborators' and 'enemies' in situations in which neither can entirely predict the actions of the other, but can adapt their behavior according to what they see the other doing. Maynard Smith applied game theory to interactions between competing individuals of the same species that use different stratagems for survival. Imagine combat in which each individual must decide whether or not to escalate the fight without knowing his opponent's decision. Maynard Smith showed, with George Price, that the interests of both combatants are best served if both decide not to escalate the fight.
