When the timer expires, the fittest creatures survive and breed. Their offspring inherit evolved brains and learned behaviors, then the cycle restarts.

Reinforcement Learning

Creatures learn during their lifetime by adjusting neural network weights when they eat, fight, or reproduce. Learning rate is an evolvable gene — offspring inherit both learned behaviors and the ability to learn.
