Marsupial Tigers Still Exist! (If Not, They'll Be Back Soon) - Phylogeny of Marsupials

Marsupials are some of the strangest of all mammals, but their story is even stranger. We explore this amazing clade that includes familiar favorites like kangaroos, koalas, Tasmanian devils, wombats, and opossums, as well as so many amazing animals that you have never seen before, and we look to discover if the Tasmanian tiger is still alive, and if not, can we bring them back from extinction. It's stinkin' rad!

I just rewatched a bunch of snake videos because I'm finally in a position to get a snake without having to worry about moving for work and it was the super dwarf retic that I finally decided on, after a bit more research of course. So yay for discounts!

Love my tiger from Reach Out Reptiles, just watch out for that food response! lol

[@glendas.mckinney926]

My cockatoo has never reacted as strongly and quickly to any animal that you've shown as she did to the Tasmanian tiger. So even if they *are* extinct, they are still deeply programmed into the brains of Australian-origin animals

[@KaregoAt]

That's so interesting!

[@rhiannon14982]

How did she react? I'm really interested!

[@glendas.mckinney926]

Most mornings we watch a few videos while having breakfast and then she sits close and solicits some scritches. Usually if something on the screen upsets her, she'll scream to warn her flock (me), flap her wings loudly, and climb back to her cage, the same reaction as a real threat, like seeing a hawk out the window. This is common enough that we have vocabulary for it: "it's ok, it's just TV." She usually calms down as we chant this and returns for more scritches. When the Tasmanian tiger appeared on the screen, she became very quiet and climbed away before screaming, and wouldn't come back down. Every time it showed up again, she seemed torn between screaming and flapping to alert the flock and being very quiet and hiding for self-preservation. She didn't return to relaxed behaviors at the cage, wouldn't say that it was just TV, but kept watching intensely and crouching quietly. I pulled the cage cover to block her view, but she peeked around to keep an eye out for the predator. I tried to coax her down so I could comfort her, but she was on alert until the video was over and her favorite cockatoo's daily video started.

Watching those old Tasmanian Tiger videos really gives me goosebumps. Of all the large animals to go extinct, the Tasmanian Tiger lies on such an uncanny valley in being so familiar, but you know it’s unlike anything you’ve seen before.

[@prasetyodwikuncorojati2434]

And it was so depressing too. They ever populated zoo around the world and even have offspring in captivity. Yet that still not enough to save their species from extinction

[@digitaldritten]

@@Freemanjacobt i hope so

[@Japh]

As a Tasmanian myself, it truly saddens me what happened to our Thylacine. No longer having a large carnivorous animal in the wild here has to have changed a number of other species habits and behaviours for a knock on effect too. Quolls seem to be the only other native animal that will hunt and kill, but they're so much smaller, leaving the Devils (primarily carrion feeders) to rely more on roadkill... which often leaves them to share the fate of their meal... it's a sad thing. But, sadness aside, this was another wonderful video that still made me smile! Thank you :D

[@BrightWulph]

Fellow Tasmanian here, it's just so weird that these creatures went extinct so recently too. Like they're still within living memory to a lot of people still alive, albeit an older generation, today. It's certainly exciting news that's on the horizon with attempts to clone and revive the species, but the question does remain just because we can, does it mean we should? Personally, I'd love to see a living Thylacine.

[@Tasforestworker]

Another fellow Tasmanian here,' They' are not extinct !

[@Japh]

@@Tasforestworker Well, you’re going to have to back that claim up 😄

[@Tasforestworker]

I can only direct you to 'Thylacine awareness group of australia' for some trail cam fotos from Tas and mainland videos as well as testimony from many people recorded from ALL over oz not just Tas. I know what i saw and more than likely have a very good handle on the Tas bush compared to most if not all on this site. If you have a closed mind nothing myself or any other witness will change your thoughts. Literally hundreds of witnesses post supposively the extinction date plus thousands of plaster casts of prints and poo and fir samples ...its starts to build up. I might add from first hand , a poo sample collected from Tas was sent to Adelaide Uni . For DNA testing and it came back as Numbat ????? No numbats in Tas and it just so happens numbats are closest related species and they didn't know/want to test for thylacine.

Actually, I think this went into a lot more detail on marsupial taxonomy than I got doing a biology degree. Then again, there wasn't a lot of information offered on mammals, and the detail on different mammal groups focused on those found in BC, Canada. Which includes exactly one marsupial, the virginia opossum.

[@pearltheangryarrow1444]

I’m an Aussie in my 50’s and when I was at school there was a genuine hope that the Tasmanian Tiger was still out there. Sadly I struggle to believe it now. But wow, I cannot tell you how amazing it would be if it could be brought back and I could live to see one!

[@IMADINOSAURNOTABIRD]

I mean, New Guinea and parts of Tasmania are very unexplored and unknown because of thick jungle

[@TheMageOfVoid]

@@IMADINOSAURNOTABIRD They've done a lot of environmental DNA studies throughout Tasmania though. I wish it were true too, but I wouldn't hold out hope. New Guinea on the other hand, I say we set up trail cams and do enviro-DNA studies there. Even if we don't find Thylacines, rainforest biomes are teeming with bio-diversity and therefore perfect for discovering new species. New Guinea is still definitely under-explored and researched.

[@IMADINOSAURNOTABIRD]

@@TheMageOfVoid Great points. I especially agree with the New Guinea part, because I mean things like orangutans live near there, what other amazing, unique creatures like those may lurk within the thick forest. New Guinea is also one of the few jungle strongholds left in the world, beside the Congo and Amazon. It’s sad to see all the rainforest and the diversity carried with it disappearing as a result of human greed.

[@thewarriorseagull3968]

Hello from Australia. We'd love to have you back too. There's a lot of reptiles in Australia that are very misunderstood. You could probably bust a lot of myths and de-demonize some of our beloved snakes and crocodilians. Don't have enough right now to donate to patrion, so I thought I'd add encouragement. You're very welcome in Australia

[@darcieclements4880]

I don't live in Australia, but I agree with this person that a lot of the world doesn't understand the reptiles in Australia because they stopped exporting them a long time ago so the few that we have in captivity don't really represent the full species. We also tend to have a lot of misconceptions that change the way that we care for the animals outside of Australia that have long been corrected in Australia but have never really left that country and I think the animals in these other countries would benefit a lot from that information. Dav Kaufman has done a lot with busting myths about various pet reptiles by visiting their native habitat so he would be a good person to collaborate with for at least one trip to Australia. But if I'm being completely honest, multiple trips to Australia to cover a variety of different species in their many different habitats and talk about the differences between the wild populations in Australia, the captive populations in Australia, and the captive populations outside of Australia would be of great benefit to a lot of people.

[@Doxymeister]

@@characterblub2.0 My Mom used to feed our farm cats their cat food on top of the air conditioner to keep the dogs from getting it. One night the dogs really set up a clamor so Dad goes out to see what's happening. There's this opossum up there eating cat food! Dad tries to get him down and he bites Dad, so we had to trap and observe it for a month to make sure it's behavior didn't change (chance of rabies?) So this silly opossum gets fed cat food and dinner table scraps, as well as garden scraps since we were busy canning tomatoes and pickles at the time, and peaches. A month of this, and we turned him loose then almost couldn't get him to leave, LOL, and he was fat and sassy--and didn't have rabies, thank God. They are adorable dorks indeed, but can be annoying as well.🤣

[@elonstruths1475]

It still boggles my mind, ever since I first experienced it at university, that there are paleontologists who can take a single molar and instantly tell you whether the extinct animal was a marsupial, placental, or multituberculate (which were super common mammals in the Cretaceous and Paleocene that may not be either metatherians or eutherians).

I am somewhat amazed their haven't been more expeditions to the forests of New Guinea to set up trail cams! Could the Thylacine truly have survived there? That would be an incredible story of survival. Either way if we bring all of these recently extinct animals back that would be an incredible achievement

[@hobbybrauer]

It will never work and even if it works for some species these will not have a viable habitat for a reintroduction so what is the point in bringing them back? Rather focus on saving the biodiversity we still have today

[@MrToradragon]

There are some ethical questions, but, lets set them aside as there is some even bigger one, do we have enough unrelated specimen to set up sustainable population and prevent inbreeding?

[@hobbybrauer]

I agree this is a practical issue for many of the extinct species they try to bring back. However, the impact of inbreeding on the survival of a species/population highly depends on the organism. Some do well with very few founders, and others do not deal well with inbreeding at all. For me, the bigger question is how to best conserve the biodiversity we still have today with the limited resources available. Scientist claiming that the cloned mammoth will be able to roam free in Alaska and Siberia are delusional. This will never happen for many reasons. So, de-extinction is a pure theoretical possibility but can never be a feasible solution to save and bring back biodiversity on a planet that faces rapid climatic changes and large-scale habitat destruction. It would be a very wrong signal for society if de-extinction works, as it would suggest that it does not matter if we drive species to extinction if we can bring them back with a DNA sample.

[@Your-Least-Favorite-Stranger]

@@hobbybrauer De-Extinction has always been interesting to me for the reasons you addressed; should we bring the animals back, what sort of world are we reintroducing them to? Would they thrive given we're already driving so many other species to extinction with the consequences of our actions? Is it ethical to bring an extinct animal back knowing they'll be the only ones of their kind, essentially limiting their opportunity for life to scientific research? What would it mean to reintroduce these species to the wild and what effect would their presence have on already precarious ecosystems? I would be cool, but I think we need to address some other problems (climate change and rampant pollution) before we take the plunge into bringing these animals back in earnest - we can still run the experiments on a back burner because it's no doubt a useful thing we should be doing (gotta retain species destroyed by poaching and human carelessness somehow), but we need to make the world a more sustainable, hospitable place first.

[@MrToradragon]

@@hobbybrauer I think that we do not have one single solution how to preserve biodiversity as it is threatened by different factors in different place of the world. We have to have different solution for places where the pollution is main issue, where bad agricultural practices are problem, where overfishing is problem and so on. Issues in Europe and Northern America will require different approaches than problems in e.g. Northern Africa and in Northern Africa issues are different than in central Africa. And the issues can vary between countries and regions in given country. Regions that are overusing their water resources will need different solution than regions where biodiversity is threatened by logging and so on. I would not be that critical of habitat destruction as destruction of one type can lead to creation of different one. For example open pit mines and quarries are often places where endangered species can thrive as those provide otherwise uncommon habitats. But in general I would say that the response to most of the problems we have is use of available technology that will lead to reduced pressure on natural resources, but it will not be entirely without footprint as we simply need some space for water storage, some place to put desalination plant and plants that will deal with waste, as well we need some navigable rivers, some space for highways and somewhere where we can mine necessary resources. At the same time we must accept that the Earth is highly dynamic system and that the climate and environment changes and there are some aspects of this that are out of our control and thus we can't keep the world from change as some sort of museum exhibit. Regarding to de-extinction, I don't think that people would say: "Oh it is OK if we hunt them to extinction, we can bring them back anytime we want to." I see it rather as a tool to fix mistakes from the past when ecology was not yet well understood.

[@mboatrightED300]

Would love a deep dive intro dasyuromorphia and diprotodontia! Also, fun fact about the bilby is that there is a strong push in Australia to have the Easter Bilby instead of the Easter Bunny, since rabbits there are an invasive species that needs to be removed (also, Easter is in autumn and the connection to rabbits came from Easter being in the spring).

Hi! I'd like to say that I really enjoyed the format of the video. What I think makes this video better than most of the similar ones is the fact that whenever Clint talks about something or some place, we see an image of it (which is also done most of the time in other videos, but not as consistently). I thinks it makes the content so much more approchable than whenever something is said without being shown. I have a much easier time following the complicated trains of thoughts that are necessary to explain phylogeny.

[@OpEditorial]

If Attenborough's long-beaked echidna is still out there, then there's a chance the Tasmanian tiger (which for frame of reference went extinct when the late Queen Elizabeth was a child) could be the discovery of the century.

[@sidstevens9035]

Actually declared extinct in 1986 as is the norm. Fifty years after the last live specimen died.

[@LottieDeLuscious]

That’s not a great reference why don’t you just say the range of years

I know it’s a different video, but your ChatGPT video was the most interesting thing I’ve seen in a long time. I love how you set up your victory in a structured way from the beginning. Starting with defining your terms, setting ground rules and discussing basic principles, taking it to its logical conclusion. Wonderful video

I worked at an outdoor education facility 20 years ago. We were given a Virginia Opossum to use as an educational animal. Her name was Cotton Candy. She would bite me almost every time I handled her. Wasn't an aggressive bite, but more as if she saw my hands as food. She would basically chew on my hands. So in my experience thay will bite once they have become accustomed to people.

[@Wooksley]

I love how every animal is Clint’s favorite animal…

[@Warmachine_23]

Back in 2007 my Dad took me and my sister to Australia, including a week in Tasmania, and we all swear we saw a Tasmanian tiger run across a road near Cradle Mountain.

[@Luubelaar]

My parents have friends who live out near Mudgee, NSW. Lots of locals around there are certain they've seen thylacine. National Parks and Wildlife are aware. I mean, if the Wollemi pines could stay hidden from humans since the last ice age, imagine what an animal capable of running and hiding could do in the rugged, almost inaccessible places where the pines were found.

[@88porpoise]

​@@LuubelaarLots of people have also seen Big Foot. Is it possible a small population survived somewhere? Yes. But it is extremely unlikely, especially given the extensive efforts over the decades to try and find any solid evidence of them.

[@terrygoyan3022]

I was surprised that Clint didn't use the term adaptive radiation to describe the marsupials of Australia. Clearly if they only arrived once from Antarctica, it's amazing that they have filled so many ecological niches. Especially in such a short (geological) time. This was fascinating. Thanks for sharing all this great information Clint!

[@jdhall420]

just found this channel and it has quickly became one of my top 3 favorite channels to visit on youtube, i am working my way through the back catalogs, I love those time periods and this guy makes talking about it interesting, Some channels some how find a way to make talking about something as epic, mysterious and awesome as dinosaurs and other ancient creatures boring.

This was great! 45 extra minutes of this for Patreon? Yes please! ♥️ Going to go watch that now, forget sleep! 🙂

[@brfisher1123]

I think a phylogeny video on the entire synapsid clade would be awesome! I'd imagine that if any of the basal non-therapsid synapsids were still around then they would be considered "reptiles" as well. It just so happens that the extant amniotes considered "reptiles" are all sauropsids, just look at the Permian synapsid dimetrodon for example.

[@geodkyt]

Yes, THIS. ❤

[@danielarato4021]

Thats true… The recent exclusion of stem-mammals from Reptiles is just nonsense to me… Birds are reptiles, so are we mammals. Who could say that that ancient scaled, hardshelled-egg-laying, lizard-like creature that gave rise to all amniotes wasnt a reptile??

[@brfisher1123]

@@danielarato4021 Well said, even the clade containing amniotes and the extinct tetrapods that were more closely related to amniotes than to modern amphibians is called "reptilliomorpha" and many of the stem-amniotes were lizard-like in appearance.

Amazing video, such a lot of info on a complex subject, explained in a way that finally makes sense. Tectonic species distribution, amniotic eggs, different types of placentas, prehensile possums and Tasmanian tiger clones. :)

[@rwild9356]

A video talking about the convergent evolution between carnivora and dasyuromorphia would be rad! I have heard that a trick question on certain animal-skull-identifying tests is to put in a tasmanian tiger skull which most students would mistake as a canid. I would also love to hear more on the thylacine revival project

That was probably the best ad placement I've ever seen, Clint. It tied right into the topic and showed me something that I never knew I wanted until just now.

[@Queso-Dip]

I don’t know why but the thylacine has always given me an uncanny feeling, it just feels like some ancient creature that wasn’t supposed to be photographed.

[@geodkyt]

A video on the dasyuromorphs would be cool. As well as what someone suggested above (whether a single video or a short series), covering synapsids as a clade (bonus points if you concentrate on extinct or basal lines and limit most of the extant content to connections with living clades... the diversity and wonderous spectrum of extinct synapsods is mindblowing).

I had no idea about the dwarf and super dwarf retics. I haven't kept any reptiles in years, but I've been wanting to again. I think I found what I want to save for, I've never wanted a giant snake but I think retics are the prettiest snakes ever. Also, if they do bring thylacines back, it will become my singular life goal to see them in person. Every time I see that video of the last one alive, restlessly pacing in that tiny enclosure they had her in, i get choked up, ever since I was a little kid. I love them so much.

even if there's a chance they're still out there, hearing about animals that have (possibly) gone extinct so recently always brings a deeps sadness thank you clint for providing this level of education for free in a way that is easy to understand and fun to follow, even for those of us who don't have English as their first language genuine question though: why are the marsupials so cute

[@DragonFae16]

Marsupials present some very unique challenges when it comes to cloning. Not only would you need to find a surrogate to carry the fetus, you'd also need that surrogate to be large enough to carry the joey in its pouch for the next 5 to 6 months while it developed to a stage where it could survive hand-rearing. Because there has never been a joey of any marsupial species that has been successfully raised by hand before the age that is close to them developing fur. In fact, when rescuers go out, if they find a joey that is below a certain size in a dead mother kangaroo's pouch and the joey is still alive, they will simply euthanize it because it is well known that young joeys can't be kept alive.

[@BrightWulph]

It'll be tricky, but I do believe it is possible its just a matter of finding the right surrogate or artificially creating a "pouch" for them to survive in. Either way it's fascinating and exciting to think that a recently extinct (or deeply hidden) species could come back.

[@Unpainted_Huffhines]

My dog really enjoyed this episode (playing on TV). I tried to explain that the little furry marsupials weren't actually squirrels or bunnies, but he didn't understand.

[@terryhunt2659]

An acquaintence of mine, a former zoo keeper (including of hyenas) and an active cryptozoologist, has searched for recent evidence of thylacines in Tasmania, interviewing locals and surveying likely terrain. It's well documented that thylacines smelled very similar to hyenas, and on one occasion, walking along a forest path, he noticed that distinctive smell in the air.

[@rhiannanthomas1639]

Okay, who else wants to watch Clint go to New Guinea to try and find a Thylacine? (And also, of course, whatever other super neat critters he might be able to find!) Also, I'm ALWAYS into that kind of thing, Clint. At least as far as talking about phylogeny is concerned, anyway. :)

[@davood123]

[@bustavonnutz]

Plenty of formerly assumed extinct species have been found to survive in sustainable populations. Without serious expeditions into Papua or Tasmania I find it difficult to completely write off the Thylacine as extinct. It will be interesting to see what will happen if Colossal succeeds with their Thylacine project if people really do end up rediscovering the species. Fingers crossed that they're still out there.

[@BrightWulph]

As a Tasmanian I know that a lot of Tasmania is covered in extremely dense bush/forest, all the Thylacene has to do is just retreat so far inland away from human populations to be kept a complete secret/hidden from most people. It's why so many people who regularly go deep into the bush claim they have seen them, because its so far out of the way and they rarely bring back any footage/photos its enough to sew doubt into people. But after a while, you have to wonder or start to hope that they're out there somewhere, just hidden away out of sight.

[@bustavonnutz]

@@BrightWulph Not even to mention that the expeditions launched so far have been by hobbiests or were short-term camera trap observation studies, definitely nothing thourough or comprehensive enough to say that they aren't out there.

[@BrightWulph]

@bustavonnutz Exactly, all it'll take is dedicated research and time to set up a long-term expedition. Technology has come a long way since the 80's, the data is out there, it just needs the funds.

[@suchnothing]

I think dragons, griffons, and centaurs would all have to be related, even though they look super different, because they all have 6 limbs instead of 4. It would be fun to discuss how a vertebrate got to 6 limbs in the first place. Did their upper limbs split into two somehow?

[@dracone4370]

@@suchnothing Wyverns are often treated as cousins of dragons, and thus not true dragons, which would suggest they did have common ancestor that the two split from quite some time ago.

[@iapetusmccool]

​@dracone4370 wyvern are probably just dragons that lost one pair of limbs, just like some lizards have lost one or both pairs of limbs.

[@charlesjmouse]

Always excellent. A question to do with 'de-extinction' I never see discussed is "Can you ever really bring an extinct species back?" Let's say I perfectly clone sufficient 'Thylacines' to found a viable population. What those 'Thylacines' will never have is Thylacine parents - as a general rule the more complex an organism is the more of it's behaviour is 'learned' rather than 'instinctual'. If you have no way to properly 'teach' your 'Thylacines' how to be Thylacines are they really Thylacines at all? On a less esoteric front, what if the clone's behaviour won't fit the niche(s) occupied by the extinct species you attempted to bring back? FWVLIW: As a generality I think any species we can bring back for which a viable empty niche still exists should be brought back, if we are ever able - I have my doubts. That principle should equally apply to extant species where they are 'missing' from a former range that they could still occupy.

I'd be willing to take a young thylacine and have it raised by an adopted stray dog.
