sailing south through the maze of tropical islands across Malaysia and Indonesia will lead you to an invisible barrier between two worlds. What in reality is a relatively small distance, is a huge gulf between two vastly different ecological regions. Why are the animals so different on either side of this line?

A recent study has shown multituberculates produced developed young. Also, Deltatheridium and Thylacosmilus aren't marsupials but related metatherians
Goth Light Media
do you live in Frankfurt?? recognised that U4 at the immediately haha.
Thanks for the awesome vid !!
@mothlightmedia1936 What is the best way to contact you for other sponsorship opportunities?
Always a refreshing treat to see a video about Australian wildlife that isn’t rife with sensationalism.
Agreed!
Or crocodiles in wildlife parks out of their region so they can't react quickly lol
8:39 man, tasmanian tigers were so beautiful. didn't realize footage existed
They became extinct in the 1930's; the footage is from Hobart's (Tasmania) Beaumauris Zoo, now closed.
overrated.
@@rizkyadiyanto7922 id trade you for a Tasmanian tiger
The grainy footage existed for many years and was only recently remastered and colorized.
Wake up new moth light media dropped
am up, am up
AHHHH
I miss the intro!
Hold on I need to pee first
Hold my beer MLM is up.
Apart from the monotremes, the weirdest creatures in Australia are the birds, but for some reason they don’t seem to attract much attention. Australian birds are exceptional in many ways.
Have you read the book:
Where Song Began, by Tim Low?
Yeah, people talk about the big ones (Emus and Cassowaries) a lot, but not a lot about kookaburas, australian magpies, and various other birds that are unique there.
The main ways being how not like birds they sound.
Very Vocal!
Australia is truly a weird place
And we still love it. From a distance.
But Australia thinks the rest of the world is weird
@@ecurewitzWe as well as the rest of the world find the US weird lol
Kangaroo tail has a lot of meat 🍖 😳😅.
As are some of its Human inhabitants. 😎 👍
I am very happy that you’re being sponsored! I have always wondered how such a large continent‘s fauna and flora remained so isolated, even though there were potential land bridges in the past
That was a pretty sick wombat. They are badly affected by endemic mange, introduced with European settlement. It kills them eventually.
Sometimes, I wish the continents were more disconnected.
A world full of Australias would give so many different animal groups a stage to diversify.
Imagine a continent dominated by monotremes or only rodents.
I love every video. From the voiceover to the production they are brilliant. I clicked after 29 seconds:D
Rodents, carried by men on ships, would soon conquer all.
Imagine if every continent but 1 are dominated by diversed version of 1 species we know today.
Sounds like a video game world to me.
XD
@@stevenkelby2169As well as our dogs and cats, and of course us.
Raise the sea levels!
South america was so much more unique before it joined north america. HUmans killing off all its unique megafauna didnt help either
A 20 minute MLM episode? And it's only Tuesday??!! Truly we are blessed
Thank you for keeping this videos music free and soft in the ears
New World marsupials (opossums) are so interesting. Once you reach central Mexico, more or less, there are more species & genera present than only the common Virginia opossum. So they blend in a lot more, I think, than here in the US, where people call them “giant rats” and stuff. 🙄Yeah, a giant rat with a pouch and 75 teeth instead of gnawing buck teeth…lol.
They’re so misunderstood. I wanted one as a pet as a kid. And in a way, nearly got one! Not really. But on my seventh birthday, something told me to look out into the backyard; I watched as a female opossum, with five babies on her back, came clambering down the tree and proceeded to walk RIGHT UP to my window (on the ground floor). Keep in mind my family has had at least three cats at all times, too, which apparently were gone at that time. I was so shocked that this mama opossum would walk up, lay down and take a nap with her babies, RIGHT THERE in front of my window. She slept, but the babies were playing and staring at us. Best birthday gift ever. Hahaha.
That's so cute
Keep the frequency coming!! Love your take on Paleontology and the images you use to illustrate such animals 🙌🏾
Wish there was a Paleontologycon or something like that for nerds like me who find exotic animals and dinosaurs fascinating.
"Babe wake up, Moth Light Media just dropped a new vid"

Aw sweet!
MothLightMedia talks about subjects I never stopped to think about
I love when Monito del Monte is mentioned
The evolution of squirrels
Why?
Why not? That's something this person is interested in. @@angelobrinkord2204
@@angelobrinkord2204because squirrels are awesome 🐿️
@@PunishedFelix Fair enough, to each their own
Please yes do this
I am obsessed with squirrels, especially marmots and Asian giant squirrels
Damn fine content
Yeah rodents and bats are our only native placental mammals.
Dingoes are a strange middle ground as they arrived before European colonization
Good way of putting it.
Do a playlist about Australia
They are no more weird than giraffes, rhinoceroses, polar bears, llamas, bison or elk. They’re just different, not weird.
I live here in Australia and studied ecology in Tasmania. If you ever visit I'd love to meet - I love your videos. I could show you some amazing places.
was really happy seeing that Brilliant ad at the start, you deserve it
Always happy to see a new MLM video
Such high quality documentary. Ty ❤️
Thanks for another excellent video. Always get me thinking.
Humans can certainly ditch their young pre-birth, but certain people aren't particularly happy about it
Very informative. Many thanks.
Great analysis. Very interesting.
Mercifully within my lifetime Australia's marsupials have stopped being referred to as 'primitive' mammals
love your vids, thanks for sharing.
great video as always!
Brilliant video, as always!
Fascinating. Thank you
"My national bird is the Emu, and it's a pest. Also bloody delicious."
Still one of the best science channel on RUclips
Such a fully researched and wide-ranging across topics episode 🥰
I absolutely love the way you make your videos you're one of the best channels of this genre of video if I have the choice I watch this channel over nearly all others
It's always a treat when I see a new Moth Light Media video in my feed.
My relief when the original music has come back 😭 thanks Moth.
God bless he has returned
Great video!
2:10 I hope that poor wombat with mange got the necessary treatment 😢
Top notch educational program! You deserve more subscribers!
Fantastic!
Please bring back the old intro screen. It was really cool, and without it your videos seem somewhat diminished.
holy crap i have never seen that tassie tiger video in such high resolution that is crazy
love your channel, i have tried a few other biology channels and none of them shine a light (hehe) to your top tier quality
I got here as soon as I got the notification. 👍
Great video. Thank you! I still miss the little intro branding, though, and would welcome its return. 😊
My FAVORITE channel to fall asleep to. I mean this in the best way. Keep it up!
This is just brilliant!
A longer video!!! Yesss
Wonderful video. Probably the most interesting l have ever seen on marsupials!
Fascinating I've heard about the Wallace line but this really explains it
Calming voiced, ancient fauna expert is back ^.^
Great topic of choice!
I truly enjoy your channel. Its incredibly helpful to my understanding that you give timelines, geographies, common ancestry. The full spectrum really solidifies these concepts. Wild about the ostrich and the emu lineages splitting before T Rex existed. That one is gonna sit with me. Just how many bird lineages actually made it through the KPG? Man, nature and life is so amazing.
Another great video. I hope your voice is okay. Thanks for the content as always.
It’s a good day when Moth Light drops a new video :)
I think a video about the fauna of prehistoric India when it was an island subcontinent would be very interesting, it is difficult to find information about.
Great video! It reminded me to reread the way we count by the DNA separation from a common ancestor.
Excellent!
Loved the video! Just so you know though, at 11:16 you should Emu habitat not including a lot of Victoria (that southern bit), but Emus actually come all the way down to the outer reaches of Melbourne. The only reason they're not actually on our streets is because they're pretty skittish.
It gets weird down under.
@Andy_Hendrix... Yeah, I've really let the hair grow out too much.....sorry. 😅
'like the philloso-raptor'
yes. aka raptor sapien.
Oh hell yeah new video!!
Sparassodonts are stem-marsupials.
I'd love to see a video on the convergent evelution kelp had with plants. I only just learned kelp aren't plants and am now obsessed with this fact
awe sweet, my favourite youtuber posted
I love this channel
I believe it was a scientist named Zinsmeister in the 80's who predicted that we should find proto-marsupials in Antartica from 40 mya, one of the great successes of evolutionary theory and biogeography.
That wombat with mange b-roll got me like 😢
I love learning while I sleep
MOTH LIGHT MEDIA RAAAAAH
Your videos give just the right amount of depth. You and some others on RUclips give us these great pieces on animals. Please consider doing some on plants too. It’s just as interesting, and it’s an untapped niche on RUclips. Better still, plants are very well represented in the fossil record and archaic species represented in modern flora. It wouldn’t go unappreciated ❤️
...I think you'll find dingos being native is still a question to be answered.
It's nice to know that Noah didn't leave them behind.
Do a a video about both the evolution of the kagu and the hoatzin respectively
Please never stop making videos
Our animals are not weird. They’re UNIQUE.
yesss. unique and weird ❤❤
Could you please do a video on the evolution of parrots?
Now let‘s place a single pair of tigers into Australia.
We did if you're a small Australia mammal like a bettong or bilby. Feral cats are wreaking havoc here.
Those first dogs founded the dingo empire of today. Are they still good boys and girls?
Aus wildlife focus? Say no more. I'm invested.
Interesting Stuff!!! 🦘🦤🐨
That was awesome
Can you do the evolution of electric eels?
Man your content is SO GREAT!!!!! How come you don't have more subscribers!?!?!
Thanks for the Great info and images!!! 🙌🙌🙌🦘🐊
"five meter long amphibians" TAKE ME BACK TO THAT TIME NOW
Correct me if I'm wrong but weren't Sparassodonts proven to be a sister clade to Marsupials? They were basal metatherians but not Marsupials
His definition of marsupial seems to encompass all of clade Marsupialiformes (which includes sparassodonts and other extinct clades) rather restricting it to the crown-group (clade Marsupialia)
The most fascinating aspect in the history of Marsupials (and their close Metatherian relatives) is how on earth they got to South America in the first place. Because by all accounts they weren’t there in the Cretaceous.
I have an idea regarding this, but it’s a little outside of the box. We’ve known for ages about the phenomenon of “rafting,” wherein “rafts” of trees and vegetation bring land dwelling animals to new islands and continents. It’s very wildly accepted but since such events are so rare how they happen is up to more speculation. One idea thrown around is that Tropical cyclones dislodge the vegetation during the storm surge. Indeed, the one example possibly witnessed by humans, of some Iguanas colonizing the island of Anguilla, was caused by a Hurricane. But while that might account for most dispersals, it can’t account for all of them, the Canary Islands for instance do not lie in the path of any Tropical Cyclones and given their location I have difficulty believing that would’ve been different in the past, though for the Canaries the currents are favorable for such “rafting” events in general. However storm surges are not the only thing that can sweep plants and animals out to sea, Tsunamis can do that as well. That is where I think South America’s marsupials and metatherians came from. I do not know how dangerous ground zero would have been a day or two (or a week) after the disaster, but even if it was a death zone, the vicinity, and especially the island arc directly to the south of North America, would have been relatively “safe” insofar as anywhere was in the immediate aftermath of the disaster.
Their are other reasons why I think this. The origins of the “South American Native Ungulates” or Meridiungulata, has always been controversial. At first glance they appeared to be exactly that, ungulates. However many paleontologists were absolutely convinced that most of them, but especially the Notoungulates, were Afrotherians, indeed some still cling on to that notion despite its original problems and the recent compelling evidence against it. Everyone seemed to agree that the group was a polyphyletic waste basket taxon. However this controversy was not destined to remain solely in the realm of cladistics. For more than one group of South American Native Ungulate survived into the late Pleistocene, and they have sub fossils with DNA. Since 2015, not only have the Notoungulates and Litopterns been demonstrated by DNA and collagen testing to form a monophyletic group, but they have also been proven to be genuine ungulates, pretty much blowing up the Afrotherian hypothesis of their origin (much to the distress of various ego driven paleontologists who believed that hypothesis as is always the case for these things). With the fossil record of Litopterns stretching back to the earliest Paleocene, any new theory of their origin must account for how they got to South America.
My own theory, though I am not a paleontologist, is that Laurasiatheria began diversifying well before the extinction event (just like the molecular clock says). When the asteroid struck, huge tsunamis swept across the globe, not just caused by the asteroid itself but also by the gigantic earthquakes it caused. Those tsunamis struck North America particularly hard and many animals were swept out to sea. Ironically the heat shock caused by the shower of meteors coming from the impact, often alleged to be a major killer in the extinction event, could have been less severe for anything surviving on the rafts. The rafts carried with them not just North American Marsupials and Metatherians, but also the ancestors of the South American Native Ungulates, amongst other small creatures, and maybe even some non-avian dinosaurs doomed to die through starvation and/or oxygen deprivation. Given the shear amount of sea-born debris created in the disaster, it was probably inevitable that some of it would end up on nearby South America, despite the gaping burning hole in the middle of the ocean between them. After the dust had settled in the beginning of the Paleocene the newly rafted animals underwent explosive diversification in South America, as one does in the aftermath of such a large extinction event. But the ancestors of the South American Native ungulates, despite being supposedly “superior” placental mammals, did not dominate all the niches. Instead they convergently evolved to resemble the other ungulates of North America and Eurasia, in much the same manner as the Ratites evolved flightlessness on every landmass to which they originally flew.
Well done for pronouncing "emu" correctly! :D
Sorry babe can't come over new. New moth light media just dropped
I still miss the old intro ❤
Based on the brains of Marsupials and what is generally known about their intelligence I would say most living marsupials are comparatively more primitive to placental mammals, specifically dogs, pigs, cetaceans, elephants and primates. On average marsupials have less wrinkles in their brains which generally correlates with more complex cognitive ability, obviously they're quite distinct from multi-tuberculates, but compared to placental mammals, if we're going by cognitive ability I'd venture to say they are more "primitive" in this regard. Now it's possible the Tasmanian Tiger was an exception but there's not a lot we know about their cognition since they've all gone extinct.
Australia's wildlife is also crazy in that when you enter the so called "zone of habitat" you immediately start seeing that animal. Even if there zone crosses over a human habitat.
Your videos kick ass!
SUPER NICE
Congrats on the sponsor (If that something to be proud of?)
