Abstract

Most evidence supporting the adaptiveness of circadian clocks lacks rigor and is categorized as 'adaptive storytelling.'

  • Circadian clocks are believed to improve reproductive fitness.
  • There is a need for more rigorous evidence to support the adaptive significance of these biological systems.
  • Current claims of the adaptive value of circadian systems may rely on anecdotal or insufficiently tested data.
  • The analysis includes both historical and contemporary evidence regarding the evolution of circadian clocks.
