The Molecular Clock of Neutral Evolution Can Be Accelerated or Slowed by Asymmetric Spatial Structure

Illustration of a replacement event.
In this case, the occupant of site 3 produced one offspring, which displaced the occupant of site 2. The occupant of site 4 produced two offspring, one remaining in site 4 and displacing the parent, and the other displacing the occupant of site 5. Thus the set of replaced positions is R = {2, 4, 5} and the offspring-to-parent map α is given by α(2) = 3, α(4) = 4, α(5) = 4. There is no mutation in the example illustrated here, so each offspring inherits the type of the parent. Thus the population transitions from state s = (M, R, R, M, R) to s′ = (M, R, R, M, M).
