What's The Oldest Tree in the World?

Ancient trees are fascinating, but the answer to the question in the title isn't as cut and dried as it might first seem. There are two major contenders for the superlative, and Hank has all the important information on both of them in this episode of SciShow. Which one would you give the title to?

An 80,000 year old organism that uses clones to live forever and has a heart too far underground to be killed by conventional means. I'm sure it means us no harm, so long as we remember to feed the shoggoth.

Last year I found one of the oldest verified bristlecone pine trees. Though only 2,515~ years old it was still the oldest of its particular species of bristlecone. It was life changing in a weird way to touch something that's been alive since before Alexander the Great existed.

My grandfather as a member of the Sierra Club in the 60’s, 70’s took my brother and I on many trips to Yosemite and the Methuselah Walk among other places. He said he knew where the oldest tree in the world was and that it was a Bristlecone Pine, but he couldn’t tell us which one it was. We respected his wishes and enjoyed the 5 mile trek, nevertheless.

Old Tjikko is a clonal tree. The trunk is only a few hundred years old, but the root system has been continuous for over 9000 years. So we lumped this in with the clonal systems, of which Pando is the oldest known. But life is weird and hard to categorize, you could make the case that Pando is the oldest living single tree because it's a clonal individual, not a clonal colony.

As a stand alone individual tree non clone,there is a 10,500 year old Huon Pine in Tasmania. At my old primary school here in Armadale,Western Australia we had the oldest remaining Jarrah tree in the metropolitan area,dated at 1600 years old according to the plaque on it from 1966. It's surrounded by a shopping centre car park now but still living.

[@SciShow]

We probably should have included Old Tjikko, but we sorta lumped it in with the clonal colonies (some of which are much older) because it is a clonal tree...it's trunk is only a few hundred years old, but it's root system is far older. When trees fall, often their root systems will continue to survive and sprout new trunks. Old Tjikko is different from Pando in that it is a single trunk-and-root system that has persisted for many thousands of years, making it considerably more fragile

[@SciShow]

That's a good idea...I've had that one kickin' around in my head for a while. I think it's more a series than a single video though. Keep your eye out for it!

Pando, the beginning of sentient plants...

[@garfieldmircea2006]

Nope, quite the contrary. The fact that it's 80K yrs. old means it hasn't evolved since then. Sentience is the product of evolution. I'd rather put my money on some sort of parasitic plant "hijacking" an organism with a synaptic system to be the first "sentient" plant. (Edit) In that case, it would no longer be a plant, but a hybrid :)

Alive for 80,000 years is simply amazing. It seems remarkably considering the 10k years sans romance. Isn't reproduction the ultimate goal of all living species? In any event, it must have an awesome retirement plan.

[@solsystem1342]

No, the goal is to not die, most creatures get around this by passing on their genes to their offspring but simply not dying yourself is also a valid strategy

[@heygirlieholdstill2589]

It kinda depends on the organism. Like, a fly for example: its most likely primary goal of life is to reproduce before it dies. but a tree is more likely to want to survive _and_ reproduce/pass their genes. But if you really want a scientific answer you probably shouldn't be asking a KZbin comment section.

the age of these tree's are mind blowing holy crap

[@kdbgvxsv]

Yes the dendro comes from the greek word dendron, which means tree, specifically fruit tree, as opposed to timber (which is hyle in greek). The chronology comes from the latinised version of the word khronos, which means a defined time or a season As you said the dark rings are made in winter, and the thicker lighter rings in the summer. They're really xylem vessels that carry water through the tree and they only show up because of the different rates of growth through the year Hope this helps:)

[@LeviJohansen]

It's true! :D

[@ranjitsarkar3126]

What is true?

[@ranjitsarkar3126]

@cupheadfangamer8481 so you are saying that you are not alive. The root system of the tree works like a regeneration process ,if a tree connected to the root dies then another tree grows from the root. It is kinda like cutting and then regrowing your hands and as time passes the whole body changes but it is still you. I guess you agree with me that it is still you whether it's 7 years ago or now (after 7 years every single atom in an average human body replaces.)

[@TheLousyGames]

Erm.. your english is fine. also i have no idea about your question

[@troyhavok8605]

Just a guess, but I would think that the black holes would converge and grow into a more massive black hole. At the same time, as all that super-dense matter collided and pressed into a singularity, I would think there would be a massive energy release.... except that the newly formed, massive, singularity may stop all that energy from escaping.... unless the energy released was greater than the force of the gravity generated by the singularity. Like I said I'm not an astrophysicist and I'm only guessing, but I'd love to see what an astrophysicist would have to say about this. There are too many guesses involved with black holes, since we can't see them.

[@kingsfoot]

Your English is just fine! Keep posting interesting questions. Please

[@garfieldmircea2006]

I see you have been misled by the poor naming of such objects. Black holes are not actual holes, they just seem that way. Imagine a sun burning so bright, it would go out of our visual spectrum, hence you can't see it. That's a black hole. End of story. Also, you're equating "black", from black hole, to absence of energy/heat. Quite the contrary. The energy/heat there is so intense, that our sun-scale visual receivers (eyes) can't see that high.

[@tretre7324]

...

[@grw1935]

Wow I dont know where to begin on this one

[@tgpgrimreaper]

I'm quite certain that you're just trolling, but I'll bite. There's a concept of BC and AD. BC means "before Christ" and AD mean Anno Domini, which is Latin for "in the year of our Lord (Jesus Christ)". This system is what they based their year "numbering convention" from, which became standard all the way to modern times. Think of it as a "number line", counting from positive numbers to negative numbers (sans the negative symbol). For example, if we count in centuries, from 500 AD to 500 BC, it would look something like this: AD 500, AD 400, AD 300, AD 200, AD 100, 100 BC, 200 BC, 300 BC, 400 BC, & 500 BC. Traditionally, the convention for AD years, you put the AD before the year, but you can also write/say 500 AD, etc. So, by saying the world is only 2014 years old, you basically just counted the AD years, and not the BC years. They also changed the BC and the AD, to be more religion-neutral - we have CE (Common/Current Era) and BCE (Before Common/Current Era) now. CE replaced AD and BCE replaced BC. So there you go.

[@foreveragainOK]

Circular reasoning, like Darwin championed: common traits indicate common ancestry vs. logic, which is the cornerstone of the 'scientific method.' Testability and observation. For example, 99% of a creature is in its soft tissues; these are lost over time and only the bones > fossils remain. The 1% is open to interpretation. If one has an assumption such as 'deep time' (lawyer Lyell, whose 'Principles of Geology' were assumptions without E and O (experiments and observation) circular reasoning will create a mind picture of 'what was in the past' but which can't be proven by E and O. * Thousands of years is within the biblical time frame, but not millions of years. If the Flood was only a few thousand years ago, this is within the time frame of the oldest trees; millions of years do not parallel the 'deep time' hypothesis.* Check out Dr. Edmund Schulman, for some insight when he applied empirical science (not assumptions / scenario creating / sci fi)... for eg., on giant sequoias: "Does this mean that shortly preceding 3275 years ago all the then living GS were wiped out by some catastrophe?* Note than even secular geologists are accepting the possibility of catastrophism for shaping the Earth's face, not long ages. Eg., 70% of rocks on Earth are sedimentary. By definition these are created by water action plus sediments, not deep time. Also fossils are also created by catastrophe: rapid burial. So both fossils and rocks are likely young (this can be E and O). You can test for yourself, throw a dead fish on the beach and bury another in sediment. See Mt. St. Helens for demonstration of what a few decades after catastrophism looks like: an ancient topography. * a brief primer on tree dating 1. trees might grow more than one ring in one year. 2. ring dating must use rigorous, replicable crossdating -- comparative validation with other trees 3. but even CD does not always work; some rings are very faint, and again some trees produce more than one ring a year... 4. different dates for the same tree may sometimes be obtained 5. inconsistent ring growth ... eg., tropical trees may produce multiple rings -- uneven use of carbs. 6. a tree may configure a countable ring in a few weeks (emphasis). On a tangent we note that the human mutations (@100 per generation) weaken each generation, and the total human race life span is only a few thousand years old: genetic entropy / mutational meltdown, etc. Secular scientists have been astounded that the true human common ancestors are mtDNA 'Eve' and Y-chromosome 'Adam' with ages under 5,000 years. Now, even if they are off by a thousand years or so, this is still within the biblical timeline, and not with the 'deep time hypothesis' ... See 1000 Human Genomes Consortium. Further, if this is true (E and O, remember) then humans could not have lived even 50,000 years ago, because we would be extinct ... let alone millions of years ago. As fossils and rocks, the true human age is again within only thousands of years. Hm, biblical timeframe. Further, this is evidence that mutations are a very bad thing, this is why they are called birth defects... another nail in evolution's coffin that mutations are beneficial. Mutations are proven to be detrimental. How can they 'evolve' any species? E and O has shown this across the board to be a false idea.

Hot air rising from the black top of the road and meets with cooler air above. The hot air has a differing density than the cooler air. The difference in densities causes the light the refract or bend as it pass through the area. The density of the air is not homogeneous and so, like with the air above a fire, there is a distortion or waves in the refracted light image.

I am guessing that has some special relevance to time, hence chrono, from chronos.

I saw these pine tress with my Dad and brothers back in 1976

[@SkyeSong777]

Just, wow. I'd assumed it would be a sequoia. Instead I learned about two kinds of trees I hadn't heard of before. :)

2:50 hahahahaha very good one! I feel sorry for Pando...

[@firestone181]

There's a prehistoric tree that has existed since the Dinosaurs. Really old as well. Why didn't you include the Something woodii??

[@MSpacer]

I just saw his mold video, and Pando reminds me of a huge colony of mold. All the roots are connected. Maybe the first trees evolved from molds? I'm kidding about the evolution.
