Practice question · True or false
An all-Dove population is not evolutionarily stable, because a single Hawk introduced into it would win every contest without being injured and would spread.
Hints
- In a world of retreating Doves, what does a lone Hawk face?
- The Hawk always wins uncontested, so its strategy increases in frequency.

True
Why
True. Among all Doves, a lone Hawk wins every contest without injury, so it out-reproduces the Doves and spreads - meaning all-Dove cannot be an ESS. This is why the population settles at a mixed equilibrium instead.
