Example text

Many cells (such as neurons) exist as viable functioning entities throughout the life span of the organism. Other cells end their individual existence by dividing mitotically into two daughter cells, which will themselves undergo mitosis later. Does the term “life span” refer to the individual cells or to the whole clonal line of cells? If, for example, we choose the former alternative, then we are equating organismal death with mitotic reproduction. If we choose the latter definition, then what does this definition mean when the organism dies even though the clonal lines of cells of which it was composed are still alive at the point of death?

5. 5b and c attempt to identify some of these complexities. Would it be more beneficial, then, to study the age-related decrements that take place within the life span of one individual and to determine their importance by comparing them with the mean population values? This has been the goal of the longitudinal studies undertaken by Shock and colleagues (1984). This type of study design is very powerful and has contributed much valuable information that otherwise could not have been obtained. There are two problems here.

Simply knowing its chronological time for one individual gives us no useful information with which to determine the rate of aging of that individual. Knowing the times of death (or the lengths of the life spans) for numerous individuals raised under similar conditions will allow us to determine whether the probability of any single individual’s dying is constant. A constant probability throughout the time period studied implies that the chance an animal will die in any given period is not related to the age of the animal.
