Fitness of the hybrid population in an example run. Fitness collapse occurs after the 5th hybridization (red dashed line). Just before then, individual networks with very low fitness appear, indicating imminent collapse. Even after the collapse, a number of networks maintain high fitness, but the fitness average (green line) has dropped to a low level.
