Abstract: We present a simulation model based on the Penna model to study the population evolution. The wealth of the individual is considered in the model. We define increasing ratio α and decreasing ratio β of the wealth presenting the individual wealth variation, also define minimum wealth PROMO which works when one reproduces. We study the influence of α and β on a species' survival or downfall, and the influence of PROMO on the age distribution of a species. According to the different values of α and β, we find diverse regimes where a species will survive or die out, and even the regime where species' survival or downfall are very sensitive. We study the relation between life expectancy and the wealth of the individual, finding that life expectancy doesn't increase but decrease a little when the wealth of the individual increases.
