In 1965 Hayflick proposed that the limited division of normal cells was a manifestation of aging at the cellular level, and we have studied normal human cells, particularly fibroblasts, as a model for in vitro aging, attempt

https://doi.org/10.1007/978-3-658-36609-4One way to gain an understanding of any biological process is through the use of mutant analysis and selective breeding to generate stocks which have genetic alterations in that process. We have taken just such an approach in the analysis of aging.

Erfahrung und Kategoriales DenkenWith respect to the evolution of longevity, two fundamental questions are considered. 1) When did senescence arise? and 2) What role did sex and DNA repair play in lifespan duration?

Mutant Genes That Extend Life SpanOne way to gain an understanding of any biological process is through the use of mutant analysis and selective breeding to generate stocks which have genetic alterations in that process. We have taken just such an approach in the analysis of aging.

Demographic Consequences of Natural Selectionpective of a student of evolution, the statement seems a trifle parochial, and some qualifications and additions seem justified. It seems parochial in three respects, which we will call the dimensional, the ontogenetic, and the phylogenetic.

Genetic and Environmental Determinants of Longevity in ,he power of living long in such various degrees?” As if in partial reply, he later suggested that, “in answering the question as to the means by which lengthening or shortening of life is brought about, our first appeal must be to the process of natural selection.” Today, with a century’s worth of h

Informational Structure of the Developmental Tree of Multi-Cellular Organismsan be conceived of as terminal nodes of a binary tree initiated with a zygote as a root. Information associated with the process of cell differentiation can be expressed by means of labeling the branches of the developmental tree. Specificity of a given cell is determined by the history of its divis
