Evolution: after so long, so many hard ships, so much effort, finally we can fly! Penguins: I’VE BEEN STARING AT THE EDGE OF THE WATER, LONG AS I CAN REMEMBER, NEVER REALLY KNOWING WHY-
One other fact that may need to be taken into consideration; New Zealand developed a number of flightless birds due to the lack of predators in general on land as well as in the sea.
Well, at the time New Zealand was not that different to other landmasses in terms of predators, not only because of a lack of many large predators globally, but also because it still had animals like crocodilians and small mammals that would later go extinct
Yeah..when we broke away from Aus, only mammals that would've been capable of travelling over could have made it on land. Therefore we only have bats as our only indigenous mammal, they flew over. no snakes as well. Since flying meant extra energy, the birbs decided to just live on the floor or low branches. Sadly, humans introduced rats, possums, cats and dogs which killed off much of them including the majestic moa. Local tribes or early english settlements also hunted em quite a lot since they were easy af to snag.
Axolotls didn't evolve this. They do indeed have an adult form, but the few habitats that they live in (as they are extremely endangered) lack a specific chemical that triggers their metamorphosis (I believe this is iodine). Axolotls have been made to become adults in laboratory environments. However, neotony (which is when an organism stays in its juvenile stage) has evolved several times, and so must have some evolutionary benefit in some cases. In fact, there is even a theory that all modern chordates evolved from the neotenous larvae of an early tunicate (tunicates, or urochordates, are fascinating in and of themselves; their larvae have a notochord and are free swimming, but the adults lack the former and are sessile!).
@@themicroplanetblog1316 it's possible to force an axolotl to metamorphose. The result looks like a tiger salamander, but the transition is unnatural and shortens the axolotls life so the axolotl has physically evolved to not react to those pheromones as strongly as tiger salamanders And is also incapable of producing them. Edit: sorry for the misunderstanding I typed to soon, that was my fault. But not to be rude your comment is kinda misleading, in the start it says that axolotls didn’t evolve this then it talks about Neotony and that’s a form of evolution?

@Timothy Somerville All species are transitional to new species or going extinct. The evidence for transitions in the history of life is overwhelming, not just from abundant fossils but every other line of evidence as well. Evolution is a fact, observed every day in every way and inferred from past evidence. No faith required. Just the facts. BTW, science doesn't do proof. That's for math. Science does confirmation of testable predictions or showing them false.
@Timothy Somerville Actually it is. and observing the fossil record trhugout the eaons it is possible to observe the similarities between species, how the enviroment around them changed and how that change affected the pressures under which they lived, thus altering the way they evolve. Let's take the Titanoboa, per example: it is observable that these giant snakes lived in a period of great heat and increased biodiversity in the rivers of the region of moder Amazom, which gave them the means to be bigger. That's particulary noticeble when you observe that there was no colossal snakes before (when the dinossaurs had the upper niches ocupaied and would be to great a competition) nor after the titanoboas (coinciding with the cooling with the planet, which wouldn't allow the survival of such big reptails). There, an example of transition of snakes from normal and big sized, to gargantuan and then back to normal and big. In relation to the lexicon of our friend over there, I would like to remark that a word is not fancy just because you do not understand it. Greek and Latin terms are comom use in science because the first is a dead language and, thus, don't change over time, and the other is being used in the west for scientific naming since before Rome itself, so it is a basic pattern by now. Also, your argument about seeing an Asian Culture, in the way the colegue upwards presented and that you put it, is wrong, although he shows understanding of it while you do not. There is not something like a single "Asian Culture" given how big and diverse Asia is. So no, you have not seen, putting bluntly, "Asian Culture" unless you refering to a much major cultural spectrum which has in commom only it's location on a world map. Would be the same as saying you know Canada's culture because you were in Mexico and since they´re "near" than they the same. Furthermore, your proposition that since you haven't seen something, it isin't real is wrong. You cannot see, nor experience the crushing pressure of the sea floor, still, you trust the information that is sent to you that down there you would have every bone of your body flatenned by the weight of the sea alone. The universe is too big for us to explore and undertand it all in our short lives, so we need to relly on other people telling about things we ourselves have not seem and talk about the work of phenomena we do not understand. And while it is valid that we take everything with a grain of salt, if the vast majority of scientists have been suporting a given teory for centuries, with no new information ever questioning it, it stands to reason that is the truth, or at least, a sufficent version of the truth for or day and age, but a part of THE truth, notheless. It is the argument of the engineers: If you have the plans for a house but 99 of the hundred engineers you asked says the house would fall if built, you would not trust the single one who says it will stand. Also, reduce the insults, we are trying to make a civilized discussion here.
It is sad that documentaries about penguins usually only show them on land during their nesting phase. They look clunky and slow, but in the water they truly do fly.

Please make a video about insect evolution! From crusteans living in the sea to the first insects! So many people know about the vertebrae evolution from fish to reptile and nothing about insects!
I just read the little Roly-Poly is the only creature of its kind on land. They are the link you are looking for, I believe. I think I saw a recent SciShow video discussing that
Chris P not really, it's a cool animal but it's still a crustacean. For example: the platypus isn't the missing link between reptiles and mammals, doesn't matter that it lays eggs like a reptile :)
This is like being in grad school all over again. I worked on penguin feather microstructure in paleontology grad school at UT Austin in a lab almost entirely devoted to penguin evolution. Definitely think I touched some Waimanu bones while in Texas. One of the other grad students was working on the evolution of wing-propelled diving and worked with some New Zealand paleontologists who worked on Waimanu. Also, my grad advisor discovered Inkayacu. Did you guys consult Dr. Julia Clarke at UT Austin? This is a lot of what she researches.
It's weird that penguins never took the leap into the big oceans such as other land mammals, whales. Perhaps we need a couple of million years more before we see deep sea penguins at the same sizes a s blue whales.
In the book *After Man: A Zoology of the Future* by geologist Dougal Dixon, penguins did just that, after whales went extinct. Two species are depicted, the porpoise-like porpin and the baleen whale-like vortex.
yes you talked about Little Blue Penguins! i recently learned they exist and they're one of my new favorite animals (too bad there are none at the zoos near me.)
@@nuamarusaenz6548 Many animals in zoos are also free. In the wild most animals are not that free because not only do humans restrict their territories but other animals do too.
Look up the Chinese tonic, "Pantocrin", made from deer antler,, I read in the book, "Chinese Tonic Herbs", written by Ray T... ? ("Tenuchigowan", spelling phonetically as best i recall from 20 years ago).
probably the first thing we call a deer got cancer in its horn buds (where the horns grow out of on the head), but it didn’t die and the cancer didn’t spread anywhere else
It would be helpful for reference, if when showing the dates when they jumped from island to continent to continent, if you would show the land masses as they appeared then, rather than how close they appear today.
@Michael F. Tommey Not everything. The first reptiles, the first amphibians, the first fish, the first mammals, and maybe the first birds were quite small. Probably true for most vertebrates too. And prehistoric microbes were just as small as today's.
I'm just imagining people sized penguins being as inquisitive and bold as they are now, just walking up to people and it's both terrific and terrifying
Huge penguins: I'm big. I'm scary. I'm hungry. Humans: AWWWW IT'S SO CUTE AND SQUISHY CAN I HUG IT PLEASE PLEASE Huge penguins: *surprised Pikachu face
My kid and I have been watching your videos since the onset of Covid. Thank you for providing this content, and kudos to your contributions to educational history.
So mysterious that there isn’t a single fossil of the necessarily very long transition periods between major evolutionary stages of literally any species.
Something I really like about this channel is that you guys say things like "it could be this, but maybe this, we're not sure". I don't watch TV myself but when I am around people that do they always really stretch the truth, present the least likely explanation like it's the only one and fact, or just lie. You guys seem to avoid that which I really appreciate. Thanks for all your quality content :)
@@conqwiztadore2213 Laziness had nothing to do with it. Diving deeper than many whales is hard work, and digging out molluscs from the sea bottom with their tusks is too.
Why has nobody ever mentioned megafaunal penguins before?! I needed to know this. There are tons places where you can learn about mammoths, mastodons, wooly rhinos, etc. and even other mega birds are pretty commonly cited, elephant bird, giant emu, and other giant land birds... but NOBoDY ever mentioned mega penguins before that I ever saw. This is totally new information to me.
Please don't stop making these videos while we're all quarantined. We NEED you. Please stay safe and healthy and keep safe distances from each other w/ minimal crew while doing it though. But.... can you like keep making them from your basements or something?
Thanks for making these great videos during these period of uncertainty and fear.always grateful for sharing your knowledge.Wishing everyone the best for the tough times ahead.
Never clicked on an Eons video so quickly. Penguins are my favorite. Are there theories as to why the penguin didnt expand beyond the southern hemisphere or of a similar separate evolution in the northern? Was hoping to a little something on that.
Supposedly it has to do with land predators that will eat their eggs, and possibly an inability to withstand warmer temperatures as they get closer to the equator. I'd like to know why we don't have river penguins - there are river dolphins...
There are penguins that live as far north as the Galapagos Islands just south of the equator. Perhaps competition from other sea birds such as auks prevented them from moving further north.
Etymology for those who are interested: Waimanu "water bird" in Maori Kumimanu "monster bird" in Maori (Yes, "manu" means "bird" in Maori. I don't speak Maori; I just looked this up.) Anthropornis "human bird" from Greek
1:25 That is actually wrong. They're semi aquatic, because they're unable to spend all their time underwater, and still have to come on land to lay eggs and keep them safe.
@@conqwiztadore2213 hes right. That's the basics of aquatic versus terrestrial animals. If you can still come on land and move around, you're not fully aquatic.
Seriously, almost every modern animals’ ancestors after the K/T extinction started to grow much bigger than their modern descendants. (Reptiles, crocodiles, and birds)
OK, HOW did I go to primary school in NZ & never learn about our human-height paleo-penguins?? 😳 Thank you as always PBS Eons for enormously expanding my knowledge of our long history! 🙏
Just like how birds give up flying when ever they lands on an island not inhabited by any land predators, every single main lineage of sea-going birds have their version of the penguin. In the petrel lineage we have of course penguins, but that's not all. From Suliformes (cormorant, gannet, frigatebird and anhinga) we have the Plotopteridae that also got huge before going extinct in the miocene. And from Charadriiformes (gull, tern, skua and puffin), we have the recently extinct giant auk, which is what the word "penguin" originally refers to.
Awesome content! I suspected before that penguin ancestors looked like guillemots and razorbills .maybe next time a video about Abelisaurids rise to apex predators in gondwana,
Fun fact, penguin came from the Great Auk, which was a flightless cousin of guillemot and razorbills and were called pengouin in many languages (scientific name is pinguinus actually ^^). And in french, we call the auks "pingouin" and the penguins "manchots" (literally armless XD), which cause a great confusion when translating english "penguin" ^^
@@eritain Exactly. Whether you Anglicize the final "e" as an "ee" sound, or whether your keep it Romance as an "eh" sound, the point is that the "-bile" in the word "mirabile" is not pronounced like the bile stored in our gall bladders. "Mirabile" is Latin for "miracle" (lit. "spectacle" or "a thing to behold"), and is pronounced accordingly.

thank you pbs eons for this video i absolutely loved it! it would be cool for a semi follow up discussing the other extremely large sea dwellers like ancient sea lions/ toothed whales
I guess I would stay on Eons because I can't afford the subscription, even the internet is my neighbors. I enjoy your lectures. Thanks for sharing knowledge.
I absolutely loved this video!!! I've been questioning myself about how penguins gave up flying for diving for years since they are my favourite animals!!! I'd like to point one thing out, though: On the minute 6:38 of the video, the penguin species that was illustrated to compare of the size of the Emperor penguin (Aptenodytes forsteri) to that of a human being IS THE WRONG ONE...that illustration is actually from a King penguin (Aptenodytes forsteri), the closest relative of the Emperor, it even belongs to the exact same genus ("Aptenodytes"), but it's slightly smaller, it's more abundant, skinnier, way more colourful & unlike the Emperor, which only breeds in the Antarctic ice, the King likes to breed in sub-antarctic islands, further north, when it's ice-free most of the time, such as the Falklands, South Georgia, Macquarie, Kerguelen, Crozet and even in Tierra del Fuego, in Chile (the only known continental colony).
Amazing video! It's very interesting to think about oceans ruled by penguins instead of cetaceans. But, It would be very interesting doing a video about the place of the meiolanids in turtle evolution tree
As someone who lives near Sydney Harbour and its population of penguins, I can say they are the most delightful of all birds. The funniest memory of them is coming across about a dozen of them waddling down a Manly street after dark. They were in the middle of the street with houses all around. They looked like they were sizing up their domain as if they were rulers of the universe. Because they live and breed just meters from houses and swim in a harbor full of ferries, ships, and yachts they are fairly fearless around humans. I am sure, that in their minds we are their pets, put here for their amusement. In the daytime it is not uncommon to see them swimming beside the ferry when crossing the harbor. I love our penguin neighbors.
The genomes of all living penguin species have been sequenced. academic.oup.com/gigascience/article/8/9/giz117/5571031 The data show clearly that penguins share a flying common ancestor with the seabird Order Procellariiformes (albatrosses, petrels, shearwaters, and storm petrels), which lived close to the Cretaceous-Paleogene boundary (66 million years ago), marked by the mass extinction event which wiped out the non-avian dinosaurs and most birds. Their genomes also show that penguins have lost many of their taste senses.
A 6-foot penguin? From behind you wouldn't be able to tell if it was a bird or a person in a suit!

Don't forget there beautiful musical talents
@@cintronproductions9430 I knew that. But did you know they also like to wear cute red and white hats?
Happy feet reference?
They also have brand loyalty for colas

"Sure, bro. C'mon, let's go!"
Those giant penguins sound kinda like an avatar animal...
Love penguins. They look regal and goofy at the same time.
Also hard as nails.
Atom-Phyr Royals are often goofy, to much inbreeding I guess!
I love that they always put the animal next to the person, to really put the size in perspective! Really helps to picture it!

So did Allan Poe
They didn't say anything about blind albino ones though.

Giant penguins look like they could pierce your abdomen repeatability leaving a bunch of see-through holes
Accidentally finding this channel is one of the best things that has happened to me in the last year. Keep up the good work!
This is like being in grad school all over again. I worked on penguin feather microstructure in paleontology grad school at UT Austin in a lab almost entirely devoted to penguin evolution. Definitely think I touched some Waimanu bones while in Texas. One of the other grad students was working on the evolution of wing-propelled diving and worked with some New Zealand paleontologists who worked on Waimanu. Also, my grad advisor discovered Inkayacu. Did you guys consult Dr. Julia Clarke at UT Austin? This is a lot of what she researches.
Another fun fact:
In NZ Waimanu literately means "water bird"
Wai: Water
Manu: Bird
Is Waimanu Maori for penguin too?
It's weird that penguins never took the leap into the big oceans such as other land mammals, whales. Perhaps we need a couple of million years more before we see deep sea penguins at the same sizes a s blue whales.
I'd like to see one of that size
Probably because the niches were already occupied by mammals and fish.
In the book *After Man: A Zoology of the Future* by geologist Dougal Dixon, penguins did just that, after whales went extinct. Two species are depicted, the porpoise-like porpin and the baleen whale-like vortex.
i don't think being the size of a blue whale is really an option when you have to return to land to breed.
@@kelbyreid7254 Check out After Man. The book has a species of filter feeding penguin called the Vortex.
yes you talked about Little Blue Penguins! i recently learned they exist and they're one of my new favorite animals (too bad there are none at the zoos near me.)
Can confirm, they are the best. I have seen them in the wild and at my local zoo, and they are the cutest!
It is not a bad thing that they are not in a zoo... They are free! Be happy for them.
@@nuamarusaenz6548 Many animals in zoos are also free. In the wild most animals are not that free because not only do humans restrict their territories but other animals do too.
Can you say anything about evolution of ruminants, especially deers? I've heard that there were some weird cancer-related stuff about their antlers...
Look up the Chinese tonic, "Pantocrin", made from deer antler,, I read in the book, "Chinese Tonic Herbs", written by Ray T... ? ("Tenuchigowan", spelling phonetically as best i recall from 20 years ago).
I'll check that out, thank you
probably the first thing we call a deer got cancer in its horn buds (where the horns grow out of on the head), but it didn’t die and the cancer didn’t spread anywhere else
@@iainmawhinney8867 does this mean that one day the jackalope could be real?
@@iainmawhinney8867 Wait, cancer can be inherited?
It would be helpful for reference, if when showing the dates when they jumped from island to continent to continent, if you would show the land masses as they appeared then, rather than how close they appear today.
I speculate penguins became less colorful as they became prey. Or when they started to obsess about getting promoted.
Ocean camo: dark on top, light underneath. Good for hunters and hunted.
1:49 "they're really specialized for underwater life" *shows the most adorable awkward movement 💕
I wonder if living on a ground predator free island like in new zealand lead to flightlessness and island gigantism
We know that it does. There are many, many cases of that happening all over the world with a range of unrelated species.
Yeah, new land predators spreading to the living habitats of the giant penguins might have wiped them out..
It certainly led to penguinism
New Zealand wasn't predator-free at the time? Neither was Antarctica - check out the video on Marsupials.
The world is shutting down but we still have PBS Eon! Thank you for releasing this video!
Damn, penguin ancestors were huge!
@Michael F. Tommey Not everything. The first reptiles, the first amphibians, the first fish, the first mammals, and maybe the first birds were quite small. Probably true for most vertebrates too. And prehistoric microbes were just as small as today's.
I'm just imagining people sized penguins being as inquisitive and bold as they are now, just walking up to people and it's both terrific and terrifying
Yeah, but they were big enough to ride on their backs as they swim, or piggyback on land.
Huge penguins: I'm big. I'm scary. I'm hungry.
Humans: AWWWW IT'S SO CUTE AND SQUISHY CAN I HUG IT PLEASE PLEASE
Huge penguins: *surprised Pikachu face
My kid and I have been watching your videos since the onset of Covid. Thank you for providing this content, and kudos to your contributions to educational history.
I don’t know, having a penguin that’s a foot taller than me stare down at me sounds pretty intimidating
Look up the cassowary. (shudder)
I probably sound like a kid but i really love that you guys show pics, animation and vids
Marine reptiles: *die*
Birds and mammals: "It's free real estate"
Evolution is so fascinating (and mysterious)!
So mysterious that there isn’t a single fossil of the necessarily very long transition periods between major evolutionary stages of literally any species.

Something I really like about this channel is that you guys say things like "it could be this, but maybe this, we're not sure". I don't watch TV myself but when I am around people that do they always really stretch the truth, present the least likely explanation like it's the only one and fact, or just lie. You guys seem to avoid that which I really appreciate.
Thanks for all your quality content :)

They were 🐘 that got lazy and lost Thier legs but kept Thier tusks
@@conqwiztadore2213 imagine
@@conqwiztadore2213 Laziness had nothing to do with it. Diving deeper than many whales is hard work, and digging out molluscs from the sea bottom with their tusks is too.
Why has nobody ever mentioned megafaunal penguins before?! I needed to know this. There are tons places where you can learn about mammoths, mastodons, wooly rhinos, etc. and even other mega birds are pretty commonly cited, elephant bird, giant emu, and other giant land birds... but NOBoDY ever mentioned mega penguins before that I ever saw. This is totally new information to me.
And now they have evolved into an operating system with many species we call distros, amazing!
Please do an episode titled "When India was an island". Thanks.
Yesss, I second this
Poli saanam
Please don't stop making these videos while we're all quarantined. We NEED you. Please stay safe and healthy and keep safe distances from each other w/ minimal crew while doing it though. But.... can you like keep making them from your basements or something?
the moment yxou realize HP lovecrafts giant penguins in the mountain of madness are based on actual fossils.....mind = blown
As some who is obsessed with penguins my life is more complete knowing this new information
Thanks for making these great videos during these period of uncertainty and fear.always grateful for sharing your knowledge.Wishing everyone the best for the tough times ahead.
Ay, another victory for the great courses plus in the great sponsorship wars of 2020. Brilliant, what say you?!
Love that video. Dont forgot the 2 evolutionary history episodes: one about pinnipeds and the other tyrannosaurids
Never clicked on an Eons video so quickly. Penguins are my favorite.
Are there theories as to why the penguin didnt expand beyond the southern hemisphere or of a similar separate evolution in the northern? Was hoping to a little something on that.
Supposedly it has to do with land predators that will eat their eggs, and possibly an inability to withstand warmer temperatures as they get closer to the equator. I'd like to know why we don't have river penguins - there are river dolphins...
They are not adapted to the land predators of the north, like polar bears and wolves.
There are penguins that live as far north as the Galapagos Islands just south of the equator. Perhaps competition from other sea birds such as auks prevented them from moving further north.
Penguins along with turtles are two of my favorite animals when I was a kid. There's something fun and fascinating about them.
A new EONS video is EXACTLY what I need right now! ❤️ Thanks you guys! Stay safe and healthy!
Etymology for those who are interested:
Waimanu "water bird" in Maori
Kumimanu "monster bird" in Maori
(Yes, "manu" means "bird" in Maori. I don't speak Maori; I just looked this up.)
Anthropornis "human bird" from Greek
1:25 That is actually wrong. They're semi aquatic, because they're unable to spend all their time underwater, and still have to come on land to lay eggs and keep them safe.
Ok professor what ever you say
@@conqwiztadore2213 hes right. That's the basics of aquatic versus terrestrial animals. If you can still come on land and move around, you're not fully aquatic.
Awesome, thank you everyone on PBS, nice script and incredible animation. 👍🏼💙
Seriously, almost every modern animals’ ancestors after the K/T extinction started to grow much bigger than their modern descendants. (Reptiles, crocodiles, and birds)
I wish they had stayed big. Giant penguins are way cooler than elephants and whales.
I really like it that they use metric units here.
Smallish waddling tuxedo birds 🤣🤣🤣❤️
OK, HOW did I go to primary school in NZ & never learn about our human-height paleo-penguins?? 😳 Thank you as always PBS Eons for enormously expanding my knowledge of our long history! 🙏

Amazing net

I have loved penguins since I did a science report in 5th grade oh so long ago. Really would have loved to have seen a 6 foot tall one.
"See what I did there?"
Me: "I SEA what you did there."
Good one😩👌
First thought on the murre.
"Alcides are evolving to be the next penguins!"
Then I realized that already happened but we killed it.
R.I.P., Great Auk with Big Dreams.
I love penguins! They look so cute and fancy :)
Giant penguins make me feel anxious😂
Just like how birds give up flying when ever they lands on an island not inhabited by any land predators, every single main lineage of sea-going birds have their version of the penguin. In the petrel lineage we have of course penguins, but that's not all. From Suliformes (cormorant, gannet, frigatebird and anhinga) we have the Plotopteridae that also got huge before going extinct in the miocene. And from Charadriiformes (gull, tern, skua and puffin), we have the recently extinct giant auk, which is what the word "penguin" originally refers to.
Oh, and there is also a flightless seaduck the size of a goose that survived until the Holocene in the North Pacific.
Awesome content! I suspected before that penguin ancestors looked like guillemots and razorbills .maybe next time a video about Abelisaurids rise to apex predators in gondwana,
Fun fact, penguin came from the Great Auk, which was a flightless cousin of guillemot and razorbills and were called pengouin in many languages (scientific name is pinguinus actually ^^).
And in french, we call the auks "pingouin" and the penguins "manchots" (literally armless XD), which cause a great confusion when translating english "penguin" ^^
I have to say this, but it really goes without saying. I LOVE PENGUINS!!!
2:05 - Rete mirabile is pronounced like this: “REE-tee mir-AH-bil-ee”. In Latin it means “miracle network.”
I would have gone with reh-teh mi-ra-bi-leh, but potato, potato. Point is, Latin doesn't have silent-e spellings (or any other silent letters really).
@@eritain Exactly. Whether you Anglicize the final "e" as an "ee" sound, or whether your keep it Romance as an "eh" sound, the point is that the "-bile" in the word "mirabile" is not pronounced like the bile stored in our gall bladders. "Mirabile" is Latin for "miracle" (lit. "spectacle" or "a thing to behold"), and is pronounced accordingly.
keep up the Good work Eons, you all are the best
In addition there were; literal *Giant* Goliathal Species of Penguin that easily dwarfs Humans
The DORUK doubt
I don't think that's true. But maybe some day they'll discover one. Crossvallia and Waimea were only slightly larger than an average human male.
@@dondragmer2412 p. Klekowskii was nearly 7 feet tall and anthropornis was 5'10"
@@killerqueenisbestmanneko8419 neither of those are larger than humans. Neither of those "easily dwarf" humans. The tallest man ever was closer to 8ft than to 7ft.

If you want to dwarf and almost 7 ft man you need to he atleast 14ft tall.

its sad that we're all in that state
It is but I’m glad they so many people are trying to flatten the curve. “It’s Okay to be Smart” dropped a good video about it the other day
I like the size comparison thanks PBS
I absolutely loved this video!!! I've been questioning myself about how penguins gave up flying for diving for years since they are my favourite animals!!!
I'd like to point one thing out, though:
On the minute 6:38 of the video, the penguin species that was illustrated to compare of the size of the Emperor penguin (Aptenodytes forsteri) to that of a human being IS THE WRONG ONE...that illustration is actually from a King penguin (Aptenodytes forsteri), the closest relative of the Emperor, it even belongs to the exact same genus ("Aptenodytes"), but it's slightly smaller, it's more abundant, skinnier, way more colourful & unlike the Emperor, which only breeds in the Antarctic ice, the King likes to breed in sub-antarctic islands, further north, when it's ice-free most of the time, such as the Falklands, South Georgia, Macquarie, Kerguelen, Crozet and even in Tierra del Fuego, in Chile (the only known continental colony).
penguins and albatri are my favourite birds 💕
Puffins
I can't even fathom a penguin 6 feet tall, it just does not compute... even the image next to her for scale, it still seems weird and unreal!
Amazing video! It's very interesting to think about oceans ruled by penguins instead of cetaceans. But, It would be very interesting doing a video about the place of the meiolanids in turtle evolution tree
"It's not a smol birb."
You PASS!
Bembebil Cocamberbatch would love this.
As someone who lives near Sydney Harbour and its population of penguins, I can say they are the most delightful of all birds. The funniest memory of them is coming across about a dozen of them waddling down a Manly street after dark. They were in the middle of the street with houses all around. They looked like they were sizing up their domain as if they were rulers of the universe. Because they live and breed just meters from houses and swim in a harbor full of ferries, ships, and yachts they are fairly fearless around humans. I am sure, that in their minds we are their pets, put here for their amusement. In the daytime it is not uncommon to see them swimming beside the ferry when crossing the harbor. I love our penguin neighbors.
The genomes of all living penguin species have been sequenced.
academic.oup.com/gigascience/article/8/9/giz117/5571031
The data show clearly that penguins share a flying common ancestor with the seabird Order Procellariiformes (albatrosses, petrels, shearwaters, and storm petrels), which lived close to the Cretaceous-Paleogene boundary (66 million years ago), marked by the mass extinction event which wiped out the non-avian dinosaurs and most birds.
Their genomes also show that penguins have lost many of their taste senses.
Cool post! 👏
