But we never see the other theoretical possibilities, namely, animals which grow and breed quickly with long lifespans; and animals which grow and breed slowly with short lifespans. The former is a physiological impossibility, and the latter would lead to rapid extinction. Allocation of the resources available to a mammalian species Normal functions Biochemical synthesis Metabolism Respiration Cell turnover Movement Feeding and digestion Excretion Reproductive functions Gonads, gametes and sex Development Gestation Suckling Care of offspring Maintenance functions All those discussed and listed in Chapter 3 The above conclusions can be best applied within particular taxonomic groups, such as mammals, or birds.

On our death certificate a single cause of death may be given, but the reality is that if we did not die from one cause, we would die from another. The fact that one organ-system fails first, should not blind us to the fact that there is a multiplicity of changes occurring in molecules, cells, tissue and organs during ageing. Chapter 5. The Ancient Origins of Ageing Not all organism age. It is well established that populations of bacteria or yeast can go on growing forever, as long as nutrients are provided.

40 Chapter 5 Consider two animals A and B. A can reproduce sexually, and also has a body which can maintain itself indefinitely, by replacement of somatic cells as required. B can only reproduce sexually, and its body consists of non-dividing cells which will age and die. In an ideal environment A might do better, because it can survive and reproduce indefinitely, where B can only reproduce for a limited period of time. In Darwinian terms A appears to be fitter than B. Therefore, one might think, ageing could not evolve.
