While Jonathan was alive Queen Victoria married Prince Albert, Samuel Morse received the patent for the telegraph, Beau Brummell died and Oliver Wendell Holmes was born. Jonathan is older than Canada and Hong Kong.
I would slightly correct the statement in the article: "The World’s Oldest [Known] Land Animal Ever". But after reading through it, I'm afraid that animals living in the wild (which are not fed and cared for) probably wouldn't reach this age, so the statement may actually be correct...
It's the oldest known land animal in modern times.
For example, a tortoise could have lived a couple thousand years ago and lived a couple hundred years. The people of that time may have known about it over the generations. Yet, we today have no record.
"ever" is said a lot but it's hard to substantiate.
Jesus Christ, this Hyper Text Markup Language page served via the Hyper Text Transfer Protocol over a Transmission Control Protocol connection can be so tiring sometimes.
I am sensitive to claims that we know more than we do, it is true. A lot of this is pandemic-related; I see a lot of claims about what we know about the virus that seem totally uncalibrated to the strength of the evidence, and in that context, sloppy/overconfident thinking/expression has actual consequences.
The Testudine lineage is more than 200 million years old.
I'm confident that some tortoise, somewhere, lived in isolated splendour longer than Jonathan. It's just a numbers game, holding 190 up against 200 million and squinting a bit.
Not to take anything away from the old fellow! He's earned his laurels.
We do seem to have a hard cap of around 120 which
basically hasn't moved - we are just bringing the averages closer to it. I'm optimistic we'll go past it but not without some advances on a different level of everything so far.
I think we have too few people still approaching 120 to know whether that apparent cap is more than "just" the combination of the risk of multiple mortality causes all getting high enough to make it unlikely.
Knock out or reduce a couple of the big ones, and we'll get an idea.
It's likely there are other limits. Eg. Telomere shortening, but I don't think we can say we're hitting other limits at 120
> but we’ll need to do a bit of research to get us to 150, for instance
Indeed, but we could additionally to research also do something against the most common causes of (early) death - the more people live longer, the higher the chance is that one of those who has not suffered a preventable death is the one that lives to be 150 years.
And there's a lot that we can easily tackle at relatively low cost compared to the gains (both in productivity and years-lived): incentivize people to quit or reduce alcohol and tobacco consumption, make high quality food affordable and accessible to everyone (=combat "food deserts"), reduce working hours in a first step towards 40 hours and then 30 or even 20 hours, reduce commute times, mandate vaccinations for everything that Army soldiers get across the population, increase access to cancer awareness programs and to first-class physical and mental healthcare so that cancer and other illnesses can get detected and treated early enough...
I've heard a theory that the first person to reach 150 will also be the first person to live to 1000, because they'll be around for an extra 50 years of anti-aging research, which will buy them more time, and so on.
Tortoises (and greenland sharks) are cold-blooded, living life in the slow lane, which makes things much easier. Hummingbirds OTOH, have an insane longevity metabolism pairing. My bet is that bats, parrots and naked mole rats probably have more to teach us about longevity than tortoises.
That is entirely not true - no one remembers every detail of their life. As for the ones who do, you can do a fairly good impression thereof by simulating reliable synesthetic associations.
I don't remember every single detail, but I have clear memories from before I could walk, like watching Wizard of Oz on VHS and not being able to walk away even though I was tired of watching it. My wife says she doesn't remember anything before about age 5.
I think that for the case of the Turtle - early childhood memories would actually have a larger impression as everything about them is new making them have a bigger imprint where as there mid 80s - 150s range is probably one giant blur of repetition.
Imagine being a software developer for 200 years? Oof you would be such a crank/skeptic having to deal with all the tech changeover
With the life+70 system we have now, it would be physically impossible for photos taken today to go public domain before said person dies. "Works for hire", OTOH, are 95 years from publication or 120 from creation (whichever expires first). With those, it is theoretically possible that a photo of a toddler would go public domain before they die.
The photographer and not the subject is the owner of the copyright. So life+70 it would be with regards to the photographer. So if a grandparent photographed their baby grandchild and died shortly afterward, when the grandchild was in their 70’s the photo would enter the public domain.
At 190, he was born in 1832. Some of the oldest photographs of anything are from the late 1830's. If you stretch your definition of photography, you could argue the oldest photos are from the 1820s. But for most intents and purposes, this tortoise is older than all photographs in the world, of anything, ever.
To be fair Greenland sharks reach sexual maturity at 150 years old. So you know, their awkward teen years are probably longer too. Just imagine having to listening to angsty rock music for 80 years
Someone once told me that the finite human lifetime is not a constraint of physics or biology, but evolution. The fact that older organisms decay and die gives an opportunity for new organisms (potentially, with superior genes) to thrive.
If there was no finite lifetime, then the benefit of physical maturity would allow older organisms to perpetually outcompete the younger ones, reducing the rate of genetic adaptation and the fitness of species overall.
Does anyone with specific knowledge know if this is true? If so, it's a little bit depressing to think that aging is simply a programmed biological process, "deliberately" degrading our bodies on a schedule and killing us off to make room for something new, rather than any sort of fundamental limitation of the underlying system.
On the other hand it means that there are some benefits which are correlated with age or else this mechanism wouldn’t be necessary.
Our culture mostly looks on old age with disdain. And indeed not just old age but any kind of aging past 25. And to be sure there are many objective downsides to being old compared to young. However one does also have the opportunity to attain knowledge and wisdom as one gets older. And that can continue until one starts to become senile, which might only start in very advanced years for many or most people!
Even though they're more athletic in their early twenties, most basketball players seem to peak around 27-29, I assume because of the intersection of athleticism and skill gained from experience.
If very process of sexual reproduction that brought humans into existence is entangled with the process of aging, there is probably no reason to think that humans (or any species that reproduces sexually) could somehow change or evolve to become immortal.
I've read it's not so much that a particular aging trajectory is selected for, it's that mechanisms that shorten lifespan aren't selected against depending on ecology, social structure, and so forth. I imagine that's not entirely accurate, though, as there are some species that have definite senescence patterns that are closely tied to important developmental events (e.g., octopuses and egg laying).
It's difficult for me to imagine something that selects for individual death per se, but I can imagine certain cellular repair mechanisms and so forth, with death at a certain age being a secondary consequence, being selected for depending on a host of factors. Evolution tends to be somewhat chaotic in that what's adaptive depends on prior evolutionary history to some extent.
I mean during a long period humans were probably mainly dying of other things than old age? Wisdom and skill transfer must have had huge importance, but the chance of reaching 200 years of age must have been miniscule for a long part of our race's time on earth even if they could live that long.
I wonder if their long lifespan is an adaptation to take advantage of some extremely rare event that benefits their reproduction.
For example, perhaps their eggs are usually eaten by a kind of crab. But once every 50 years there is a a massive hurricane that decimates the crab population. In the following spawning season, nearly all of the eggs hatch. The 150 year lifespan allows them to participate in 2-3 of these rare spawning seasons.
Since the event is rare, scientists get few chances to notice it.
I think they can do simulation and then map result against actual observations. This would be very similar to "climate science" now (albeit at a smaller scale) where a lot of conclusions are done via projections of years in advances within their simulated earths.

[ 3.7 ms ] story [ 163 ms ] threadFrom the description, it seems he's spent a life eating lettuces and bonking. Not a bad 190 years.

"ever" is said a lot but it's hard to substantiate.
In a natural language, implicit and contextual cues are often more important (and can be lost in low bandwidth communication media like this).
> He turns 190 years old this year, making him the world’s oldest tortoise to ever live
I don't hear an implicit "known" in that. I hear a claim about Jonathan's being the oldest tortoise to ever live, and we have no idea if that's true.
Most people probably just take it at face value, or read it as implied in the limitations of the medium.
I passingly notice the discrepancy but disregard it as unimportant in this context.
You seem to deeply notice the discrepancy and complain that it isn't fixed every time, preferring always verbose precision over brevity.
In a live-in-person context, it'd be easily handled in seconds of conversation or just body language and intonation. That's all lost here.
“Attempting to transcribe spoken English? Yeah. Try transcribing that.”
Moving a return value into the EAX register yourself is more explicit; I don't see a lot of Python code doing that sort of thing.

Modern medicine should be able to get more people into their 90’s but we’ll need to do a bit of research to get us to 150, for instance.

It was from an anti aging TED talk I believe.
Which makes this "feature" of COVID-19 very concerning: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8201243/
I don't suppose a 200yrs 'ordinary' old human would run into any problems with memory storage.

However your point that it is older than photo technology stands.

They're estimated to live between 250 and 500 years.
I will not complain about my own 50 year search, then.
But not mammals and "cold blooded" (ectothermic) so they are probably too different to be helpful.
You'd literally experience steam power industrialisation progressing all the way to information tech era.
That would give you some incredible perspective.
Although not mobile like Jonathan, the trees and moss are really old. Some are 12,000 years old. Still Amazing.
