Mortality curves using a bit-string aging model

In this work, we studied the shape of mortality curves for a population under different conditions using a bit-string model for biological aging. More specifically, we studied how the model parameters affect the shape of the mortality curves. Although these curves are in reasonable agreement with th...

Summary:In this work, we studied the shape of mortality curves for a population under different conditions using a bit-string model for biological aging. More specifically, we studied how the model parameters affect the shape of the mortality curves. Although these curves are in reasonable agreement with the Gompertz law for the increase of mortality, for a extended range of ages, other parameters play an important role to determine the overall behavior of the mortality’s curves. •Mutation rate and age of reproduction combined do not change the overall shape of mortality curve.•Model: Gompertz region depends on the mutation rates and active mutation threshold.•Human mortality curves are well fitted for a wide range of ages.•We introduced a segmentation approach to define three different intervals for mortality curves.
