Rare Alleles and a Recent Population Bottleneck

Moreover, @agauger has published simulations that suggests varying population size can reproduced the right distribution with an origin 200,000 years ago, but those results have not been confirmed.

Where have they been published?

It can be hard to keep track of it all. Remember this one? Gauger: A Single-Couple Human Origin is Possible.

You’ll quickly see how much our understanding has grown since then. There are some questions about whether or not that result holds up in a YEC model with a population that is always exponentially growing. In contrast, @glipsnort’s simulations used a constant population size.

My population size increased exponentially until a fairly large size, and was then constant.

Thank’s for the clarification. The amount of time spent in exponential growth phase during the simulation is quite low. That is the issue that Sanford/Carter have disputed, and that @Agauger relaxes by considering a time-variable population size.
