“…However, working with a series of mu tants and wild strains of Tribolium castaneum, Soliman and Lints [1982] found a positive relationship between growth rate and life span, which was difficult to reconcile with the data disclosed in D. melanogasler. Furthermore Cohet [1975] and Cohet and David [1976] demonstrated that flies devel oped at 13 °C, a temperature out of the range tested by previous investigators, which have a very low growth rate, had a shorter life span than those with a higher growth rate developed at 17 °C.…”

A rereading of The Rate of Living [Pearl, University of London Press, London 1928] shows that Pearl’s thoughts about the meaning of inheritance and heredity, about the relations of between and within populations measurements and about the ways in which life span should be measured are unclear. New ways in which the theory should, eventually, be tested are suggested and the genetic implications of these suggested experimental ways are given. A review is made, mainly in insects, accessorily in rodents, of the different manners in which the theory has been essayed, namely by relating life span with temperature, rate of energy expenditure, growth rate and activity. It is concluded that the theory rests on a weak theoretical basis and even on a series of highly nonplausible assumptions and that, furthermore, the evidence experimentally accumulated is, with a few odd exceptions, not in favor of the theory.

“…Oscillating temperature seems to be even more appropriate. Convincing evidence was obtained in experimental studies demonstrating that developmental oscillating temperature can be an effective tool for lifespan extension (Soliman and Lints 1982;Economos and Lints 1986). Drosophila melanogaster males tended to live longer when larvae were reared under oscillating 21/25 °C (mean lifespan = 67.8±12.6 days) than when they were reared at a constant 23 °C (mean lifespan = 59.0±14.3 days) (Economos and Lints 1986).…”

ᮀ Hormesis is a common phenomenon in a number of biomedical areas. However, the basic nature of this phenomenon remains largely unknown. Therefore, significant uncertainty is inevitable in attempts to apply hormesis as a pro-health and anti-aging tool. Evidence supporting that hormetic-like effects may be the result of a generalized wholeorganism adaptive epigenetic response is reviewed. Specific hormesis-inducing interventions during development would allow to achieve an optimal balance between activation and repression of various genes and thus to prevent age-related degenerative diseases and slow aging. The reasons that oscillating temperature mild stress could potentially be used for human application are discussed.

“…Finally, it is tempting to view the in creased life span of males after development at 21/25 or 18/28 °C as compared with that after development at 23 °C as evidence for the hypothesis of Soliman and Lints [1982] that alteration of developmental temperature may have favorable epigenetic effects. How ever, it is not clear why female life span was not affected by these two alternating temper ature schedules.…”

“…Based on a comparison of the effects of constant developmental temperatures 25, 30 and 35 °C with those of a 1 day/1 day oscil lation of temperature between 25 and 35 °C in Tribolium castaneum, Soliman and Lints [1982] proposed that, because growth rate varies many times during development at alternating temperature 'a larger array of epigenetically controlled genes may be derepressed providing the individual with a larger norm of reactions with potential beneficial effects on imaginal life'. In this way they accounted for the faster growth and longer life span (measured at 30 °C) of beetles developed at the alternating temperature 25/35 °C than of beetles developed at the average temperature, 30 °C.…”

Alternating developmental temperature within the viable range 13–33 °C, with increasing amplitude around a mean value of 23 °C but constant period (2 days, a 1 day/1 day rhythm), resulted in increased duration of development, decreased body weight and decreased growth rate of both male and female flies. Life span of female flies also decreased with increasing amplitude of temperature of oscillation but that of males increased (compared to that at the mean temperature) at moderate temperature amplitude. Variation of the period of oscillation (from a rhythm of 6 h/6 h up to 2 days/2 days) with constant amplitude (23 ± 5 °C), on the other hand, did not affect either duration of development or body weight of the flies. However, life span of the females only was unaffected but that of males was increased (above that at mean constant temperature 23 °C) at the fast oscillation patterns (6 h/6 h and 1 day/1 day). Finally, life span of both sexes was positively correlated with growth rate in the constant period/varying amplitude case, whereas in previous studies variation of growth rate in the same range by other means showed a biphasic or an invariant pattern of life span dependence on growth rate. These results are in agreement with the hypothesis of epigenetic influence on life span by alternating developmental temperature and corroborate the previous conclusion that growth rate per se does not determine life span.
