What is the key characteristic of an Evolutionarily Stable Strategy (ESS)?

It adapts to the behavior of other species.

It is always the most aggressive strategy.

It resists invasion or replacement by any alternative strategy. (correct)

It is the most common strategy in a population.

How does the success of protective aggression in muskoxen relate to the concept of ESS?

It is primarily based on offensive rather than defensive strategies.

It is only successful if all individuals in the population engage in it.

Its success diminishes significantly if only few individuals participate. (correct)

It is always successful regardless of the number of participants.

Why is frequency-dependence important in Evolutionarily Stable Strategies (ESS)?

It eliminates the need for individuals to adapt to changing environments.

It ensures that rare strategies are always the most successful.

It guarantees that the most aggressive strategies dominate.

It affects the success of a strategy based on its prevalence within the population. (correct)
