May need to reset

Nobel prize research has shown how the body clock mechanism is built into all life - but if we ever want to settle other worlds we will need to find a way to re set it to a different cycle, possibly even more difficult than simply getting there.

We appear to have naturally adopted the cycle of the moon, not the sun. Imo, this is probably due to the nature of tidal flow, rather than the moon itself.

Merely a coincidence the Earth's rotational period has been slowly changing over time (and will continue to do so albeit very very gradually) and the length of day was different when our distant ancestor oozed out of the primordial soup and evolution started selecting out the ability to go with the light dark cycle. The switch from night to day resets us back to 24 hours each morning but time down a mine or on shift work can disrupt this

The Lunar day matches it's orbital period around Earth. I doubt many of us are operating on a monthly long daily bio-rythm;
Orbital period
27.321661 d
(27 d 7 h 43 min 11.5 s[1])
Synodic period
29.530589 d
(29 d 12 h 44 min 2.9 s)
https://en.wikipedia.org/wiki/Moon

There are sort of monthly long cycles though ...
Quote:
Basic rhythm details
  • Physical cycle
    • 23 days; Circavigintan
    • coordination

The Solar day has been slowly getting longer over time, so that mans natural clock of c25hrs would not be related to this phenomenon. The other obvious suspect is the Lunar day which mirrors mans natural cycle. I suspect this is a throwback to when our ancestors were coastal dwellers. Yes, I am slightly seduced by the Aquatic ape hypothesis (https://en.wikipedia.org/wiki/Aquatic_ape_hypothesis) and totally understand if most think it is bunk, as it is highly contentious .

Yup...

About the 24 versus 25 hour cycle;
Humans

Early research into circadian rhythms suggested that most people preferred a day closer to 25 hours when isolated from external stimuli like daylight and timekeeping. However, this research was faulty because it failed to shield the participants from artificial light. Although subjects were shielded from time cues (like clocks) and daylight, the researchers were not aware of the phase-delaying effects of indoor electric lights.[47][dubiousdiscuss] The subjects were allowed to turn on light when they were awake and to turn it off when they wanted to sleep. Electric light in the evening delayed their circadian phase.[citation needed] A more stringent study conducted in 1999 by Harvard University estimated the natural human rhythm to be closer to 24 hours and 11 minutes: much closer to the solar day
https://en.wikipedia.org/wiki/Circadian_rhythm

"Others" were suggesting a Martian connection, my personal view goes a bit further. I lean towards a variation of Intervention Theory, basics being that while our ancestor hominids were evolving here on Earth out of Simians ~ why we have a near 99% DNA match to such ~ There came a point when "Someone" manipulated "our" DNA to accelerate that evolution.

Earliest written records, Sumerian etc., literally discuss the "Gawds" coming from the sky, manipulating early hominids to make Humans, and then interbreeding with us. Old Testament Genesis, Chapter 6, versus 1-4(6) if true and literal would be one source of support~evidence. Simian DNA is organized on a 24 chromosone sequence, human on a 23 chromo. What is basically the second and third chromo of the simian(chimp) sequence has been fused into a single, longer4 chromosone in humans. Significant if those "sons of the gods" were able to have offspring from human females, the "sons of the gods" also likely had/have a 23 chromosone pattern.

This would suggest we humans are a form of hybrid or half-breed, half+ from Earth and half from another world. My variant of Intervention Theory has the ET source being interstellar colonists, whom may have started with a base on Mars, having a need to accelerate hominid development. Details in rough draft presented in another thread in the Science Fiction subforum here; Geminga Scenario (first couple pages of posts present the basics).

Aquatic Ape Hypothesis has much to support it, other than where(and when) on Earth such might have occurred. In my Geminga Scenario mentioned above, I suggest that the "aquatic ape" traits are part of the evidence for the ET half of our DNA, "they" had AAH as part of their origins and we homos sapiens display such as part of our genetic/DNA component we got from them.

Seriously? I know that a great many Earthlings are "looney", but we have nothing matching the natural human time cycle of the Moon on this planet.

Correct. My opinion is based on instinct, rather than fact, and thus dubious.

However, humans do appear to have a 25, rather than a 24, hour clock. Why this is so, I cannot explain. The moon is an obvious link, but I believe it is more likely we were linked to tidal forces, for whatever reason, than astrology.

While I might be completely wrong in my current belief, I'm not convinced by this latest research.

Now, the most accurate measurements to date, made by researchers at Harvard University, reveal that our natural daily rhythm is much closer to that of other living things than previously believed. The better match opens the way for experts to more effectively treat sleep problems involving night work, jet lag, Earth-orbiting astronauts, or just not being able to go to sleep and wake up on time.

By recording the daily rhythms of hormones and body temperatures in 24 healthy young and old men and women over a one-month period, the researchers conclude that our internal clocks run on a daily cycle of 24 hours, 11 minutes. “That’s slightly longer than 24 hours, but significantly shorter than past estimates of 25 hours,” says Charles Czeisler, professor of medicine at the Harvard Medical School.
Researchers previously reported a range of 13 to 65 hours, with a median of 25 hours, 12 minutes. The variation between our subjects, with a 95 percent level of confidence, was no more than plus or minus 16 minutes, a remarkably small range.”

We Humans are barely on edge of being inter-planetary capable in our travels~expeditions; hence only our Moon/Luna and Mars are likely near future "worlds" we Humans might settle. Both would require extensive under-ground living/habitation with limited and/or regulated "extra-surface activities".

Meanwhile ISS ~ International Space Station ~ Occupants have provided some clue on ET living~styles ~~~ ... for now a better study might be the crews of nuclear-powered subs that have spent weeks to months under water's surface, with little to no "re-charge" of Surface Air; yet kept going ...

The challenges of inter-plantary travel are much similar to those of undersea transit ...

I myself have a 25 hour cycle, as I found out in 1992-3 when I was recently divorced with no money, no job and plenty of time.
