WHY DON'T CIRCADIAN RHYTHMS COINCIDE WITH THE 24-HOUR DAY?
Found almost ubiquitously in living organisms, circadian rhythms are generated by body clocks with natural periods ranging roughly from 22 to 28 hours. However, they rarely match the 24-hour length of a day (hence the word "circadian," meaning "about a day"). This is strange, since species whose body clocks are resonant with the Earth's 24-hour cycle of light intensity and temperature variations ought to be the best ones for adapting to the environment and organizing daily activities.

I seem to recall Dr. Levin harping about this (through Barry). I cannot recall if the Viking claims for circadian rhythm coincided exactly with the Martian day or not. If they did coincide perfectly, would this study not show such an association of perfect repetition be one of physical precision, likely of planetary rotation and the cycle of Solar energy reception, rather than one of conveniently-imprecise life?

Really asking,
