The F deme had a size of 8866 until 2798.1 generations ago. From 2798.1 generations to time 1563.0, its size changed exponentially to 128 individuals. After that, until 84.3681, the population had a exponential change to 1700 individuals. It then changed from 1700 to 3820, starting 84.3681 generations ago, until current times, at a exponential rate.
