The Evolution of Bats
Вставка
- Опубліковано 24 чер 2020
- The Evolution of bats is a mystery because for the first 10 million years or so after the dinosaurs went extinct there are no bats and then all of sudden bat fossils can be discovered all over the world. However, just because their evolution is poorly does not mean that it is completely in the dark. This video pieces together the bits that are known and explains why there is a bat explosion in the fossil record.

Step 1: Mysterious gliding insectivore
Step 2: ???
Step 3: ALL THE BATS
Step 4 : Profit
That's what it's all about.
Same with humans
snakes too they just kinda poofed into existance
where is those transform in humans?
Im just waiting waiting for this channel to finally blow up. An actual hidden gem of youtube.
Marc he’s gotten about 45,000 subs in the past 3 weeks, so he’s growing at a much faster rate than before and will probably hit 100k relatively soon. But I hope he sees even more success in the future.
@@riot2136 funny cause i started watching about 3 weeks ago
@Thomas Krol i know what you mean from other channels, but i still wish hed get the attention he deserves

hes not going to blow up alot i mean his content is too demanding for the average yt user
When I was a kid my family use to have a couple of "bat hotels" that's what we called them,and they were positioned about 30ft up and each hotel would hold about 40-50 bats. It was glorious to go outside at dusk and see them just swarming the insects and chirping.
Did they work better than one of those zappy insect killing lanterns?
I live in the desert and at dusk you will see small flying creatures making passes at the insects under streetlights, accompanied by chirping noises.
I'm so glad somebody finally did a video on bats
@Josh T I saw there's but I just wish more channels did it
Me too
The Royal Tyrrell Museum Speaker Series had a lecture by the scientist who studied the onychonycteris fossil mentioned in this video, it's here on UA-cam and really good.
Here's the yitle/YT link to the lecture series I mentioned above: "Evolution of Flight and Echolocation in Bats": ua-cam.com/video/uQwDHJSi0C8/v-deo.html

Waiting on Tierzoo
Bats: I am going to be nocturnal to avoid predation from birds of prey
Bat falcon: I an going to end this group's whole carrier
Is that a Falcon whose parents got killed in an alley during a robbery when he was a kid and as an adult lives as millionare/douchebag by day and fights crime by night?

_"Right again, Robin"_
I still can’t get over the fact that bats aren’t even closely related to mice and rats!
Flying hedgehogs...Who knew?
In German, they're literally called "flying mice"
Correction: It's actually "flutter mice"
Guess your from a place with a Germanic language-not-English too? Flagermus here 🇩🇰 😄

I just googled the etymology of "morcego", which means "bat" in Portuguese.
It comes from Latin mus, muris (mouse) + caecus (blind). It never crossed my mind.
it's always funny to see Ken Ham on the list.
tfive24 well, he’s a kook, so...
Jeff Naslund It’s not the legit nut but just a guy’s name for irony?

I've often wonder why birds never really evolved many nocturnal species leaving the night skies to mammals especially as birds had a head start? I possibly thought it may be to do with the differences between bird and mammal brains, however Owls are an extremely successful nocturnal species? Also I often wondered that if all birds went suddenly extinct how long it would be before bats filled the available daylight ecological niches?
What is the theoretical biggest size a flying bat could evole to if there wasn't any birds?
Based off some studies our largest bats that are alive today are that their maximum size if they still want flight. But could grow bigger if they become flightless
Generally speaking mammals have brains more developed for hearing and smell whereas the birds for sight.
@@jonathanjacob2053 Really? I though using membranes to fly would allow creatures to become bigger then creatures that use feathers to fly as the membranes are able to generate more lift with less weight (This is what happened with astarcids). Would you happen to knwo where one could find this research?
I bet flying foxes and fruit bats would slip into diurnality comfortably and quickly. Just a guess. Perhaps if we lose some terrestrial carnivores (or have another ‘cat gap’) bats will descend from the skies to exploit the vacant niches and embrace their ancestry as a carnivoran. Some good thoughts you posted, perhaps owls are a special case because nocturnality is more conducive to predation as opposed to foraging
@@MrJoe99998 Pterosaurs grew to a huge size !
8:25 bats live in Finland too :) i used to watch one hunt in evenings outside my apartment in Tampere., you can really tell that it's not a bird by the way it can do 90degree turns mid fly
Every time I am outside and something is flying around just out of sight of lamp posts, someone always says why are all those birds just flying around? Those are BATS. Really cool seeing them flying around at night. I am glad they are out doing their thing and I hope to see more. Bats are awesome.
And the sound - they're wonderful creatures!!
Necromantis is the coolest animal name ever!
I'm willing to believe the predecessors of bats were specific to a small region, but their geographical dispersion exploded after they evolved flight, so it may reason that fossils of proto bats may be incredibly localized. That's merely a hypothesis
A hypothesis that’s worth betting on, I’d say.
I've read that bats were often associated with the supernatural because their faces are remarkably human-like compared to other animals, making them seem to be part human and part animal. Interestingly, this line of thinking somewhat resembles the hypothesis that bats were closely related to primates.
Depends on the bat. Fruit bats look like foxes mixed with hedgehogs IMO. Vampire bats, I have no idea. And saying "a vampire" doesn't count.
I would say, they look like pigs.
I've heard of this, though weirdly enough, bats are actually more closely related to whales then humans..
They look nothing like people, that makes no sense
What bat has human like features? Most of them have rats or mice like features while the largest ones look like canines, none of them are even close to resemble primates.
"Necromantis".
This has to be the coolest goth name ever.
1. animal that eat insects and may or may not echo locate
2. animal that eats insects, climb and may or may not echo locate
3. animal that eats insects, climbs, echo locates and thinks its easier to jump directly to insects to catch them
4. animal that eats insects, echo locates and glides,
6. animal that eats insects, echo locates and flies.
I suspect echolocation came later. It is very useful for a highly maneuverable flying creature, but not so much on the ground. Also, making noises to echo locate announces their presence to predators. By being nocturnal and able to fly, predators have a much harder time following the clicks to a batty snack.
@@wildflower1397 Yea I think the same that first 3 didn't require echo location
"Bats is closely rellated to pangolin"
Hmmmmmmmmmmm interesting
Doesn't that mean that its closely related to Carnivorans? As the closest relative to carnivorans is pangolins
The Corona virus connection? 😂
Because it is highly memeable, and making fun of any kind disaster is my what my country specialty (we struck by so many disaster we kinda numb of it)
Not a grammar nazi but Jesus
Now thinking of a night sky brimming with flying pangolins 😂
Well done video. I remember a surge in the bat population in Baltimore Maryland in the mid-late 1970s. It was odd seeing them perched outside my window.
This is a very informative video and I'm glad that this content exists for those of us who are curious about the in depth information about specific animals.
the acoustic folk
This is the most underrated channel on youtube.
I hope to live long enough to know what happen with the origin of bats.
Amazing video as always.
Yes the mystery surrounding bat flight is like the mystery of the whales, 50 years ago. The difference is whales leave nice big fossils with big bones that are unlikely to be destroyed. Bats, not so much.
Yeah they are pretty fragile.
i think its easier to find a bat fossil than a whale in the ocean (both on how the fossil is made and size of the place)
@@arturmizuno Nope. Millions year old whale fossils can be lifted up by geological uplifting processes, which is why we find so many sea fossils in hills and mountains.
But a fossil needs to be formed, and that is relatively easy in a sedimentary proces in seas.
For bats, but also the earliest birds, most likely evolved in forest ecosystems. In those, fossil formation is very hard, as forest ecosystems are specialized to recycle organic matter. Dead bats would decompose very quickly, leaving small chance for them to fossilize. That one old bat fossil found in lake sediment is exemplarisch - that's where you find good fossilizing circumstances.
But if a primitive bat does not hunt over lakes or seas, and most likely never got outside their native Forests, chances are very small you ever going to find such a bat fossil.
Watching this video outside at dusk, surrounded by mosquitos and, by extension, LOTS of bats swooping around eating them. Awesome!
So there are both bloode-sucking bats, and nectar-sucking bats.
Brilliant.
Nobody ever makes horror films about nectar-sucking vampires, for some reason.
@@WaterShowsProd
Well, horror-comedy, anyway...

Blood is simply the nectar of the veins lol
I really like the way that you talk, its so calming and very relaxing. Also it's nice to see that someone finally did an analysis of these fly-rat bois.
Yesss! I saw some people in the comments complaining that it’s monotonic, but I love how calm it is, compared to other science videos. It helps me focus on the information.
This channel is incredible.. please keep it up. I’m a dude who watches content like this to relax. And have been doing so for ten years. 5his is the first channel in years that is providing info I haven’t found anywhere else on most video platforms. Moth you are a gem in an age where science is being treated like superstition
Can u make the evolution of cats. And that "phantom" ancestor
What, "phantom", ancestor?
Cat woman
F-4 Phantom, maybe the Minecraft mob?
I am so happy you have so many patrons and views, you deserve it. Love your content.
The videos from this channel are educational, entertaining and relaxing at the same time. Really nice format, great job!
That was awesome, so incredibly fascinating to me the evolutionary origin of these amazing creatures. I didn't realize how little I actually knew about bats until now, hahah. Thanks for the great video, mate. Keep up the good work! Cheers
So great to see your channel growing, best wishes.
"Desmodus draculae" "Necromantis" so dramatic and edgy these names.
Check out the Vulcanops
Who named that? Mr spock?!
Bleh bleh bleh
Icaronychteris. Icarus of The Night. Very poetic.
Also Vampyrum and Vampyressa.
The algorithm didnt show me your video the only reason im here is because someone just liked my comment on your previous video.
I'm subscribed and supposed to be notified...
Great video.
GOOGLE IF YOU CAN READ THIS MAKE THE THE ALGORITHM LIKE THIS GUY.
This channel really is amazing.
I studied Zoology & life sciences for more than 5 years and still fascinated by the way they make their contents
I love your channel, you make thorough videos packed with knowledge and I have subscribed it for sometime, but you need to post more often.
Very glad this was recommended to me this guy’s channel is right down my alley well done
Dude your channel is so under rated omg you should have like 3 mil subs with this golden content. Keep the good work up king 👑
I think it's cool and quite appropriate that bats just suddenly appeared and swarmed out of nowhere in the fossil record !
Fantastic video, thanks. Your channel's awesome.
I love these videos, so relaxing yet interesting
Such an underrated channel
You did my request! This was incredibly interesting thanks so much
Another great video, I've always found evolution of animal body shapes so fascinating. Most likely there were many evolutionary experiments/mutations and animals with unbelievable forms and shapes, that ended up being unsuitable for its habitat and disappeared forever without a trace and we will never know.
Americans: "Don't worry. There are only four species of vampire bats."
Me knowing that most bats in Southeastern Brazil are vampire bats. 😳
Eae mano
I wish you uploaded more these videos are great
Man this video is bats*** crazy good you really need more subscribers/views
bats are cool, i had mice get in through my next door neighbor's apartment, killed those vermin(humanly with fast and painless traps). one time a bat got in to his apartment and then mine, i put in the max effort not to harm it and then let it fly out my window.
I was so excited when I saw this vid, I’ve already binged all other mlm videos and can’t wait for more!
Well done. I like your unassuming manner, going to source fossil records to document what is likely or possible. A curious and quick evolutionary path for the only flying mammal.
Great video. Keep up the good work
Very interesting as usual. Here in South America we also have a fish eating bat-, Noctilio leporinus one of the largest of the microbats (1 metre in wingspan), seen flying over cannals and lagoons to catch fish at dusk.
My congratulations on your audience. They are having interesting, polite conversations. Proud of you guys!
I know this is like the best comment section I've ever seen. I've spent more time reading and learning in the comment section than I did watching the video haha
This Channel is a gem
Wonderful! Sharing to FB.
not to sound like an ingrate but this really would've been a perfect episode to hold on to until Halloween 👌
Maybe he's planning the Tully monsters for Halloween.
@@sohopedeco when they do figure out what that thing was the explanation will be so mundane and banal that people will wonder at the simplicity of our generation for being perplexed by it
That explains why covid was passed from bat to pangolin!
can you do a video on farm animals and the niche they occupy as humans extinguished most big megafauna in all continents besides africa?
for example south america's pastures didn't have many large grazing animals for a couple thousand years before cattle were introduced, we humans are occupying those beasts niches through farming
Bats always interests me so I was interested to see this video
Just saw that you made shirts with the new neon logo, ordered! Thank you!
Hell yeah new moth light media video
Great video!
Another great video
Great topic. Interesting and informative. Thanks for sharing.👍🦇🦇🦇👍
Who else was hoping for a giant bat species?

There are giant bats. ua-cam.com/video/Qpq0Kdn28GE/v-deo.html
Good video bro.
Amazing video as always! Would love to hear you talk about rabbits, though, admittedly, there might not be much to talk about.
great video thanks
Incredible content
The emergence of powered flight In bats is super perplexing, but the theory that they descended from a line of arboreal, nocturnal insectivores seems to be the best theory to explain their morphology.
Flying animals like insects, birds, pterosaurs and bats always fascinates me because of the biomechanics of their flight! :D
I've always loved bats since my mom read me Stellaluna as a child, thanks so much for making this video, it was fucking aweseome.
great video
Enjoyed!
Great video. 👍👍👍
Excellent. Thanks.
I think BATMAN!!
🦇 😎 and I think you would love to "The Host" with the marvellous Saoirse Ronan - just for the intro! 😚 My thank so much for your awesome video! ❤️
Listening at the end where you suggest evolution pushes flying lineages down similar paths, now I wonder if there were anything like blood or nectar drinking Pterosaurs we just never found (if there were would probably be the smaller families from the Triassic and early Jurassic rather than the giant ones from later eras)
I'm curious about the evolution of plants and photosynthetic cells, would you ever do a video about the specifics of how photosynthesis evolved and plants took root?
Photosynthesis originated very early in plants. Possibly they assimilated with chloroplasts in a way similar to the mitochondria.
I was telling my fiancé about this video, and he said necromantis ‘would be a great band name’.
🤣🤣🤣🤣🤣🤣
Great info, especially the genetic linkages. A few Corrections: 1. Vampire bats don't suck blood as stated in the beginning of the video. Instead they bite then lap up the blood with their tongue. 2. Paleochiropteryx is pronounced Pale-ee-oh-KY-rop-ter-ix
Thank you!!
So well presented. Come on algorithm. Get with it.
I can see moles and bats being related
They both have poor eyesight, and both don't care about it.
@@trezapoioiuy yeah and even the face and hands a little
Okay, now I have this mental imagine of an extremely acrophobic bat.
@@trezapoioiuy Fruit bats, or flying foxes, have excellent eyesight.
_And_ Pangolins!!
What can I say? I've got BAT FEVER!
To the quarantine!
I wish everyone was interested in stuff like this
the bat @8:48 is ***REALLY*** happy with his meal. lol
Great stuff
One thing that always confuses me is where these fossils are on the land masses when the evolved. Like what did the world look like then
Hi, I am interested in making some videos in a similar style to you, can you tell me what software(s) you're using to create these videos?
Software shouldn't matter too much as there's not a lot of editing going into his style of videos, it's kind of run like a slide show. However Adobe Premier Pro is usually the go-to editing software for professional channels, but if you want a good one for starting out I would recommend Camtasia.
bats are super cute, flying fuzzballs and i´ll fight anyone who ays otherwise

Depends on the species. Fruit bats are very adorable
@@jegvids101 Exactly.
@@Jose-xh5qb only 1% of bats carry rabies
I've never understood how fruit bats have been able to thrive in an environment with hawks and eagles. Such a large and relatively slow animal must surely be easy prey for these powerful birds. Perhaps they're protected by the viruses they carry?
Patrick Fitzgerald most certainly not.... it just sheer numbers.. the colony sizes are immense so you are correct they are easy prey and do get killed often and easily... but there’s simply thousands to replace it
@@charliebowen5071 That explanation seems wrong, or at least incomplete. I would think the predator numbers would soar if that's the full story. I'll research it elsewhere and see if this has been studied.
And they're super manoeuvrable! Because their wings completely blocks the air, unlike feathered wings, they have very a different aerodynamic, making them extremely good at changing direction quickly.
Even these immense flying creatures can often times outmanoeuvre these fierce birds of prey - other times not. Some eagle species' reproductive cycles fit certain blooms of figs so they can raise their chicks on a diet of flying dogs! 😄
Hawks and eagles hunt during day, and also bats aren't slow at all, from what I've seen. The night birds of prey, like owls would be more likey predators than eagles, for sure. But owls are stealth hunters and with bats it does't work because their echolocation makes it useless.
All interesting hypotheses. I'm just adding this little known fact: Fruit bats are highly "toxic" to eat.
Bats fly by the power of jazz hands

Bats are cool, but you should an episode about bears next!
Yesss cave bears are sweet
Great Video. Congrats.
Only two little points, your phylogeny with Pteropodidae (and the other families of bats) at 4:45 is incorrect. Since now 10 years almost we know that Pteropodidae (the fruit bats) are linked to the Rhinolophoidea.
Second point, at the end about your presumtion that more fossils will be found as for the Cetarciodactylea, it is quite more challenging as the structure of the bones in bats make their conservation during diagenese really complex. So most of the time we can't find more than teeth or skulls unfortunately.
4:17 now that's a happy boi

I hope they find early bats soon that would be really cool to see

6:44 tbf necromantis is a great name for a metal band
Lol so true!
4:34 Cool artist rendition, but somehow, "I'm Palaeochiropteryx-Man" just doesn't roll off the tongue as well as the well-known comic book character's name does.
I think it rolls off the tongue better; like music to my ears. I love scientific nomenclature.
Wonder what name Robin would have in scientific slang
