Merrill A. Peterson,Robert F. Dennot a particular time and their relationship to the births that occurred prior to this time. In each case the age distribution of the population was discussed almost as an adjunct to the model and not as an integral part of it. Perhaps this was unfortunate since it was the asymptotic age distribution

Genetic Studies in Model Organismsupheld, would eliminate virtually every existing biological population as a subject for its use. One must concede, for example, that human population is exposed to migration, and that birth rates and death rates are not constant over time. In this light, one may erroneously conclude that stable theo
