The F deme had a size of 8880 until 9856.1 generations ago. From 9856.1 generations to time 3380.2, its size reduced exponentially to 5191 individuals. After that, until 278.38, the population had a exponential change to 7301 individuals. It then increased from 7301 to 9946, starting 278.38 generations ago, until current times, at a exponential rate.
