An evolutionary view of ageing suggests that mortality may be due to an energy-saving strategy of reduced error regulation in somatic cells. This supports Orgel's ‘error catastrophe’ hypothesis and offers a new basis for the study of normal and abnormal ageing syndromes and of apparently immortal transformed cell lines. 
Programmed and non-programmed theories of aging
There are compelling reasons to regard aging as an evolved adaptive program. The evidence is diverse, deriving from genetics, breeding experiments, and plasticity of life span in stressfulExpand
Evolutionary perspectives on human senescence.
What we call senescence may simply be the inadvertent consequence of surviving beyond the reproductive period. As survival is further extended inevitable declines in physiological function and aExpand
Slowing human ageing
TLDR
Studies in model organisms indicate that increasing the expression of repair and maintenance genes results in slower ageing and increased life expectancy, and it might soon be possible to achieve such slowing of ageing in humans. Expand
Puzzles, promises and a cure for ageing
TLDR
A better understanding of the targets of such interventions, as well as the proximate causes of ageing-related degeneration and disease, is essential before the authors can evaluate if abrogation of human senescence is a realistic prospect. Expand
Understanding the Odd Science of Aging
TLDR
To understand the cell and molecular basis of aging is to unravel the multiplicity of mechanisms causing damage to accumulate and the complex array of systems working to keep damage at bay. Expand
Condition-dependence in life history evolution
TLDR
A large number of studies have shown that the immune response to age-related decline is mainly driven by the immune system, and research is needed to understand more fully the mechanisms behind this response. Expand
Evolutionary ideas on the nature of aging
TLDR
Facts are considered showing that novel forms of aging and mechanisms counteracting them, antiaging systems, have appeared simultaneously with development of the evolutionary form. Expand

TLDR
Genes controlling the levels of activities, such as DNA repair and antioxidant defence, thus regulate longevity and can help to understand important features of the human life history such as menopause. Expand

TLDR
It has been demonstrated that there is a modification in metabolic pathways during ageing, and this suggests that ageing is a strategy designed by natural selection to save energy, in accordance with other saving strategies. Expand
Targeting environmental and genetic aspects affecting life history traits
TLDR
This study has a broad orientation, varying from ecophysiology to selection experiments, mutant analysis and sate of the art microarray gene expression analysis, performed on Drosophila melnogaster, the fruit fly, and was put in an integrative context with human ageing. Expand

Altered Enzymes in Ageing Human Fibroblasts
TLDR
Observations support Orgel's “error catastrophe” theory of ageing by showing that the RNA base analogue 5-FU induces premature senescence, which is preceded by the appearance of altered enzyme. Expand

TLDR
A simpler model is considered in which successive generations of the protein-synthetic apparatus are discrete and distinguishable, and it is deduced that the error frequency would increase exponentially. Expand
Commitment to senescence: a model for the finite and infinite growth of diploid and transformed human fibroblasts in culture.
TLDR
The model suggests a possible explanation for both the observed finite lifespan of human diploid fibroblast cultures and the apparent immortality of lines transformed by an oncogenic virus or derived from malignant tissue, since reducing the incubation period or the probability of commitment can convert a population with limited growth potential to one which grows indefinitely.

TLDR
An “error theory” is developed which can be applied to determine the stability of a macromolecular translation machinery which reproduces itself and indicates that any experimentally found decrease in translation accuracy with age is probably not due to an inherent instability in the translation apparatus. Expand
The stability of the translation apparatus.
TLDR
The model generalizes the model and thereby makes it more biologically realistic, and reaches the conclusion that the protein-error theory of ageing is based on justifiable assumptions. Expand
The serial cultivation of human diploid cell strains.
TLDR
A consideration of the cause of the eventual degeneration of these strains leads to the hypothesis that non-cumulative external factors are excluded and that the phenomenon is attributable to intrinsic factors which are expressed as senescence at the cellular level. Expand
