	abstract = {<div>The necessity of imposing the concept of a carrying capacity was investigated within the framework of the Penna Model. We find that the number of deaths in a population approaches a saturation point. The carrying capacity {\textendash} Verhulst factor, is the main contributing factor for deaths, over 70\%, in an 8-bit Penna model. Only 3\% and 20\% of the deaths are caused by old age and mutation accumulation, respectively. However, the effect of the common method of accounting for a carrying capacity is diminished as the bit-string length of the Penna Model is decreased. Furthermore, at bit-string length of 2, the Verhulst factor may be removed while still maintaining a finite population.</div>},
