Chapter 1: Introduction

What is an Evolutionary Stable Strategy (ESS)?

A strategy that is randomly chosen by individuals in a population.
A strategy that always results in the highest payoff for the adopter.

A strategy that is always dominant in a game.

Who introduced the concept of Evolutionary Stable Strategies (ESS)?

Thomas Schelling
Albert Einstein
John Nash
John Maynard Smith and George R. Price

What is the key difference between phenotypic ESS and behavioural ESS?

There is no difference between phenotypic ESS and behavioural ESS.
Phenotypic ESS are genetically determined, while behavioural ESS can be changed by the individual.
Phenotypic ESS are studied in economics, while behavioural ESS are studied in biology.
Phenotypic ESS are always dominant, while behavioural ESS are always dominated.

In the context of the Prisoner's Dilemma, what are the conditions for cooperation to evolve?

What is the role of punishment in the evolution of cooperation?

Punishment can stabilize cooperative behaviors by deterring defection.
Punishment has no effect on the evolution of cooperation.
Punishment can only be effective in infinite populations.
Punishment always leads to the breakdown of cooperation.

What is the handicap principle in the context of signaling theory?

Honest signaling can evolve because individuals can only afford to signal honestly if they possess the traits they are signaling.
The handicap principle has no relevance in evolutionary biology.
Honest signaling can only evolve in cooperative games.

What is the significance of the Nash equilibrium in game theory?

A strategy that always results in the highest payoff for the adopter.
A strategy that is randomly chosen by individuals in a population.
