Abstract The ubiquity of circadian rhythms suggests that they have an intrinsic adaptive value (Ouyang et al. 1998; Ronneberg and Foster 1997). Some experiments have shown that organisms have enhanced longevity, development time or growth rates when maintained in environments whose periodicity closely matches their endogenous period (Aschoff et al. 1971; Highkin and Hanson 1954; Hillman 1956; Pittendrigh and Minis 1972; Went 1960). So far there has been no experimental evidence to show that… 
Persistence of oviposition rhythm in individuals of Drosophila melanogaster reared in an aperiodic environment for several hundred generations.
The results indicate that the phenomenon of egg laying is rhythmic in individual D. melanogaster females and is controlled by an endogenous time keeping mechanism, which strengthens the view that possessing biological clocks may confer some intrinsic fitness advantage even to organisms living in aperiodic environments.
Evolution of circadian rhythms in Drosophila melanogaster populations reared in constant light and dark regimes for over 330 generations
This study highlights that, contrary to the expected regression of circadian clock evolution in constant light, rearing in constant darkness leads to the evolution of more robust circadian clocks which may be attributed to an intrinsic adaptive advantage of circadian clocks and/or pleiotropic functions of clock genes in other traits.
Eclosion behaviour of three species of Drosophila under different light regimes.
Data from experiments showed altered rhythm in the form of phase advance and phase delay in eclosion at different light regimes suggesting the role of photoperiod in the physiology of organisms.
Locomotor activity rhythm in Drosophila melanogaster after 600 generations in an aperiodic environment
Persistence of circadian locomotor activity rhythm in a considerable proportion of these flies suggests an intrinsic adaptive value to possessing circadian rhythmicity, derived, perhaps, from the need to synchronise various processes within the organism.
Entrainment of Eclosion Rhythm in Drosophila melanogaster Populations Reared for More Than 700 Generations in Constant Light Environment
The results clearly demonstrate that Drosophila melanogaster flies have preserved the ability to exhibit circadian rhythm of eclosion and the able to entrain to a wide range of periodic LD cycles even after being in an aperiodic environment for several hundred generations, suggesting that circadian clocks may have intrinsic adaptive value accrued perhaps from coordinating internal metabolic cycles in constant conditions.
Effect of different light regimes on fitness of two species of Drosophila montium subgroup
Investigations were made to understand whether rhythm changes affect fitness of two co-existing species of montium a subgroup of Drosophila, and it was evident that these two species although genetically related exhibit different responses to different light regimes.
On the Adaptive Significance of Circadian Clocks for Their Owners
The background for development of the framework currently used to test the hypothesis of adaptive significance of circadian rhythms is discussed and some of the basic criteria and the nature of evidence required to comprehensively understand circadian rhythms as adaptation are suggested.
Evolution of temporal order in living organisms
The present review is an effort to critically discuss studies that directly or indirectly touch upon the issue of adaptive significance of circadian rhythms and highlight some shortcomings that should be avoided while designing future experiments.
Adaptive significance of circadian rhythms of montium a subgroup of Drosophila: I – locomotor behaviour
Investigation of the effect of different light regimes on locomotor behaviour of the two co-existing species of montium, a subgroup of Drosophila found tremendous reduction in the activity in 30th generation flies compared to the 15th generation ones.

In all four experiments the flies on a 24-hr day lived significantly longer than the flies in the other environments, indicating that eukaryotic systems as oscillators perform most effectively when they are driven close to their natural "circadian" frequency.
The circadian program of algae
The circadian program turns out to be more complex than simply consisting of an input pathway, a pacemaker and the driven rhythms, and both circadian inputs and outputs contain feedback loops.
Resonating circadian clocks enhance fitness in cyanobacteria.
This work tested the adaptive significance of circadian programming by measuring the relative fitness under competition between various strains of cyanobacteria expressing different circadian periods and found strains that had a circadian period similar to that of the light/dark cycle were favored under competition in a manner that indicates the action of soft selection.
Twilight Times: Light and the Circadian System
By fine-tuning physiology in advance of the changing conditions, an organism can be ready to exploit the changed conditions to its best advantage.
Suppressing Drosophila Circadian Rhythm with Dim Light
Drosophila larvae were reared and allowed to pupate in continuous bright white light and the pupae were then transferred to a much dimmer blue light, where the emergence peaks broaden for about a week with little change of period.

A circadian oscillation (in the brain) of Drosophila spp. acts as a gating device restricting the emergence behavior of the adult to a limited fraction of each 24-hour cycle defined by that
Testing for Periodicity in a Time Series
Abstract A one-parameter family of tests for periodicity in a time series is proposed that contains Fisher's test as a special case. Some tests in this family have substantially larger power than
