	abstract = {In the Penna model, deaths by old age are known to artificially truncate age demographics. We propose to avoid these deaths by obtaining a parameter space plot (Penna parameters R and T, here constrained to a birth rate B=8) for which these deaths do not occur. For both T<R and T>R, the genetic diversity and number of species decreased more slowly in populations with old age deaths than those without. This confirms a difference in the genetic evolution of these populations.},

	abstract = {We consider two types of Penna model populations: VA, where the Verhulst factor is applied to the entire population, and VB, for which Verhulst is applied to newborns only. Resources are shared by summing both populations during coevolution. We determined a relative threshold carrying capacity for VB that still drives VA to extinction.},
