Phys. Rev. E 69, 041907 (2004) [5 pages]Population dynamics in the Penna modelReceived 14 August 2003; published 29 April 2004 We build upon the recent steady-state Penna model solution [J. B. Coe, Y. Mao, and M. E. Cates, Phys. Rev. Lett. 89, 288103 (2002)] to study the population dynamics within the Penna model. We show that any perturbation to the population can be broken into a collection of modes each of which decay exponentially with its respective time constant. The long time behavior of population is therefore likely to be dominated by the modes with the largest time constants. We confirm our analytical approach with simulation data. © 2004 The American Physical Society URL:
