Sycom that's evolution, baby. don't forget the fate of the mini sauropods. Doesn't take a human hand to stomp on an island recluse, just any new animal.
DISTurbedwaffle918 that's not evolution well at least the mini sauropods died off due to a natural predators the rest were salutered by humans that's not evolution that's just humans killing thousands of species
It's predators arriving in an ecosystem and doing what they naturally do. It is perfectly natural, humans are just too much of an apex predator for most animals to handle.
I'm going to buy a chain of islands and populate each with a single species. The only food source will be only available by solving puzzles. As the creatures adapt, the puzzles will increase in difficulty, and demand more creative thinking. My money is on racoons being the first learn golf.

Pigs are my pick. Intelligent, strong, adaptable, quick breeders with versatile diets. They’re very similar to humans in a lot of ways, to the point that I’m pretty sure xenotransplantation of pig organs into humans is a thing. The only real mark against them is their hooves. There’s a reason they were the leaders in Animal Farm.
As Richard Dawkins quoted from a New Zealand verse in "The Ancestor's Tale:" "No Moa, No Moa, In old Aotearoa, Can't get them, they've et them. They're gone, And there ain't no Moa."
Five years ago I was indecisive as to what to do with my life. I was majoring in English but I knew it wasn't for me. This video rekindled in me a apssiom for biology I haven't felt since I was a kid and now I'm close to finishing my biology major on my path to become a biology teacher. I always look back to it as a decisive point in my life that led to a path full of trials and tribulations, but a path I'm happy I took. I'll always feel indebted to paying back to the world in trying to inspire as much people as I can in the path of science the way this video inspired me.
The inbreeding from small populations founded by even smaller number of genetically distinct individuals leads to homozygosity in some island populations
I really like how you showed that the principle of evolution doesn't only apply to biology but to technology as well. Hmm, in a way, all of technology is part of biology, because every technological thing is invented and bulid by a living thing. And biology itself is part of chemistry which is part of physics which is based on mathematical principles. Damn, our world is amazing.
yeah I find it quite odd when people say humans and what they made is not part of nature. like a species searching for (too much) power is about as natural as you will get. any animal would take over the world if they could
I would say it's all about supply and demand - competition. So it will apply to any scenario where a specific goal is sought after for a large enough number of creatures (survival, market adoption etc.)
You stalk at night you prey at night, you're the rats. I'm the giant rat that makes all of the rules. Let's see what kind of trouble we can get ourselves into.
TREY the Explainer can you make a video on the subject of the competition for the apex niche like what you show at 3:33, based on the south american continent, because it very difficult and very time consuming for me to search informations about that because I'm French and they have a lake of scientific things in that language. I had also loved your video ;-)
+TREY the Explainer Have ever you read The Sixth Extinction, by Elizabeth Kolbert? It covers this subject quite well, and I think you'd enjoy it. It won a Pulitzer prize, too.
There was one area where predatory ungulates succeed where carnivoroians became second, the ocean. Cetaceans are even toed ungulates closely related to the predatory ungulates andrewsarcus, Entelodont, etc.
I just read an article about some studies from scientists from the Australian National University saying that homo floresiensis must have separated a lot earlier (about 1,75 million years ago) and not from homo erectus but from homo habilis.
I find convergent evolution to be such an amazing concept. It's just such an amazing show of evolution when you see traits appear repeatedly within these niches, like this glimpse of perfection that has obviously worked through time and across the planet.
16:56 *KING JULIAN TRIES PRE-WORKOUT* This was your best video in my opinion Trey. I loved every bit of it. Had to pause every 30s to look up the interesting stuff you were talking about. I immensely enjoyed this one.
We only recently find out that New Zealand sits on top of it's own continent shelf (I've been hearing some information hinting at that since the early 2000's) and it has been named as an island since at least back to colonization times. The point being that the use of island instead of continent is a construct and there is not fixed definition of what they mean. Just to put an example Australia can be considered an island or a continent depending on who you ask. Some people could argue that Europe is a subcontinent of Asia just like India, but we still consider it a continent out of convention (that and the fact that the people who come up with the term "continent" were Europeans, so naturally they considered their continent separated).
I always take away important information from these video's, so incredibly interesting. I never want them to end! I live in Tasmania, would love to see you do a video on carnivorous marsupials. Just thought I'd suggest it. Keep the great content coming :)
I wonder if someone actually still reads this after almost a year. But to my knowledge gigantism occurs when a species only competes with itself (so it has no competition by other species) und thus bigger individuals are favoured, because they can dominate smaller version of themselfes. they don't grow bigger for a lack of competition. Lack of competition would lead to diversification because small inefficiencies aren't punished as hard (by, for example, hunger not an actual punisher). The latter being in line with you statement about competition causing uniformity. I'm d'accord with your explaination for in general though i wouldn't call "growing less big before reaching adulthood" necessarily neoteny. Also my zoology prof back in bacherlor's statet, that homothermic (constant body temp. like us) animals tend grow smaller to conserve energy while poikilothermic (no constant bodytemp. like lizards) grow bigger to physically dominate better. but this doesn't really work out for me.
All these recent extinctions of unique creatures makes my depressed :(. But it was still a very interesting video and I loved how you added an adventure time song at the end.
hey TREY the Explainer have you seen the movie dinosaur island do you thank you can make a video talking about how scientifically accurate the dinosaurs are in the movie also the dinosaurs have feathers
i don't think so, most of our nutrient already goes into our brain, growing a bigger body would be a disadvantage since you would need to eat more to sustain your brain AND your bigger body, more time to eat means less time to develop our brain further, so most likely we will only gradually getting smarter with that much food resources to feed our brain and maybe grow slightly taller by a few inch
Draco master HamZ Probably not. They'd be bigger sure, but the human body has a hard limit of ~7 feet and even that is pushing it. The thing is the human heart will have to work harder to go against gravity so blood can get to the brain. The tallest people ever never exceeded the limit I stated earlier. (Goliath of Gath in the Bible was like 6'9" which would have been terrifying to the average man of the day)
technically they could, but like i said in my previous comment growing bigger body parts require a lot of nutrient and make our body bigger would mean we need to eat significanly more than we are normally, our body is a perfect match for our brain, BUT if human does evolve into a giant, they would probably become a little bit more dumb, since they favor big body to survive rather than better brains, tehy would probably act like a land version of Orca, they are smart.. for an animal but not so smart if compared to a human
Well, what is probably the main cause of us ruining everything is that we only look out to make human lives better. Humans will cut down a forest, because the choices are made by people who doing that will only improve their lives. For instance, the air in china is so bad because the people who could cut down on coal use don't care if the atmosphere gets fucked. They think global warming won't affect their lifetime, so they don't do anything about it because it gets them more money. That is my take on the idea.
More like human values has changed (for the better?), traditionally we would not understand nor appreciate bio-diversity and wonders of evolution, but as we study more and grow wiser as a specie thanks to evident based scientific methods we learn to value those things that we were once take for granted.
Because instead of sharing and using our resources for the good of all, our economic system accumulate as much power and resources in the hands of few.
We don't look out to make people lives better. We struggle to keep living while great company owners play poker with economy. They only care about profit and we would have to really get out of our way to have a micro impact in changing anything. How many Island species have you saved last week? None? I think so. Things only would change with a revolution but that's not gonna happen anytime soon
Love your videos! Especially the ones about paleontology and evolution. Another great example of this island phenomena are the Channel Islands off Southern California. There dwarf mammoths evolved from Columbia mammoths and there is a giant mouse too.
Loved your video, man! I don't understand the dislikes (even though there are only two at this point). You're giving out free information on a fascinating biological subject coherently and you're super entertaining! How could anybody dislike this? You should totally make a Patreon though! Thanks for the awesome stuff brahh!
This is the best video you've ever done! The waits between them are getting longer nowadays but this was well, well worth it! I have researched bits and pieces about a lot of the content you've included here and it is such an interesting topic! I saw a bit about Hateg Island in a documentary and thought it was like something from a Sci Fi novel! Hatzegopteryx swallowing sauropods whole, haha! Looking forward to your next one! Cheers!
hey trey just wanted to say really good video this time. Islands do play a very important role in the history of evolution. By the way i think that you should make a little series about every extinction event ever. Not just mass extinctions, but the small extinctions like the Jurassic and eocene extinctions. Some extinctions like these are very vaguely described, so if you could model the importance of these extinctions, how big we're they, that would be really helpful. (By the way for a paleo profile A personal favorite of mine would be Paleo profile Hyaenodon)
So if for example parrots evolved to become flightless ground herbivores simply because there was no need of flight to escape predators So does that mean if those flightless parrots still live will they evolve to fly again? Because there will be cats etc etc predators
this was the first vid of yours i ever saw, at the time i was really in a rough state and not doing well, but your videos were something that helped inspire me to learn more about the world we live in and try to make a better impact on the environment. I’ve been a big fan since this first video all the way back when i was in high school, graduating college soon and your videos still inspire me
Gosh, I love your videos so much!! I used to do these types of research myself years ago but now with college and a job, I barely have time for anything anymore so it's a real blessing to be able to play one of your videos in the background while I'm doing chores or work :'3
Trey, you explain it well.Just had to know how much I truly enjoy your work. Wish I had a teacher like you when I was a kid. Well done Sir, well done and thrice so.
Islands are where the devs let the lower tier classes take over to see how well they would do in similar roles. Their also places used to test new potential metas in the game. Sadly most island meta gamers don’t make it when competing with their continental counterparts 😭
trey you are an inspiration to me, your videos have inspired me to pursue science and develop a really strong fascination and interest in it thanks to these videos. Thank you
Hey Trey! I know mammology isn't your biggest field of expertise but I'd love to see you do an episode on the history of carnivorans and why they're so good at outcompeting other predators like sparassodonts and whatnot.
Another great video! always so excited to see you've uploaded, I never get to watch them first thing though because all my roommates want to watch them together! We usually have some pretty good discussions afterwards. Keep it up :D
There used to be miniature humans on an island with giant lizards? I'd love to play a game as one of them. Fighting off giant monitor lizards with spears, I could have a tiny elephant friend, thatd be awesome!
ALSO WAIT, THERE IS ACTUALLY GIANT SWANS? I THOUGHT I MADE THAT UP, MY DINO WAS A SWAN THAT LIVED ON AN ISLAND WITH NO DINOSAURS, ALLOWING IT TO EVOLVE INTO TREX SIZED OMNIVORES OMG
Okay, so I need to write the rest of this for class tomorrow and then read a few pages in..huh.. *TREY UPLOADED A NEW VIDEO!* (Drops everything and puts on headphones) Educate me with your dulcet tones Lord Explainer
It's truly amazing how you create thesevideo's. It's like a lesson of a professor, I'm even taking notes while watching this. The fact that you can see that this is not just a interest you picked up knowledge over time and wanted to talk about, but that you actually took the time to research this subject. make it really worthwhile to watch, even for these longer types of video's. just saying, good job, and keep it up.
Thanks man! I'm always happy to inform. I take great pride in my research and I'm really honored that other people respect that too. I really appreciate it ;)
im so glad you talked abt our kakapos. they're so cute, i did a tertiary studies report on them last year, they basically became too chunky to fly. bloody legends
also! you said about how there are only 100 or so more on the island, theyre actually not on our main island, im pretty sure theyre all on smaller seperate islands which are protected to try conserve them, and the islands went under strict pest control so there are no ferrets or cats etc on them:)
I think this is my favourite of your videos. So interesting! I was really interested about that small type of human you mentioned. Do you think you will do more videos on different prehistoric types of humans? I think that would be really interesting. :3
Fascinating. I remember Jerry Coyne talking about islands in Why Evolution is True. He said there are 2 different kinds of islands. Ones that broke off of the continent and others that formed I'm the middle of the sea. He said the continental islands has animals related to the ones on the continent and the oceanic islands are conspicuously devoid of terrestrial mammals, reptiles, amphibians and fresh water fish. But had plenty of bats, birds, insects, spiders, in other words, stuff that could get there. Bats, birds and even insects can be blown hundreds of miles by storms. And by using large nets dragged behind planes and ships, they found insects, pollen and such miles out to sea. That might make a cool video.
Xer Serpentine An island is a categorized by it being smaller than traditional landmasses. After a certain size threshold a landmass is no longer an island and becomes something greater. Pangaea, for example, is categorized as a super continent, seeing as it was all continents formed together.
Biology on Islands summed up:
"Cool stuff evolves... humans come and kill it"
Sycom that's evolution, baby. don't forget the fate of the mini sauropods. Doesn't take a human hand to stomp on an island recluse, just any new animal.
DISTurbedwaffle918 that's not evolution well at least the mini sauropods died off due to a natural predators the rest were salutered by humans that's not evolution that's just humans killing thousands of species

Soo say primative humans landed on a island with plenty food and water would they become giants?
most likely, if there were no pretadors of course
i don't think so, most of our nutrient already goes into our brain, growing a bigger body would be a disadvantage since you would need to eat more to sustain your brain AND your bigger body, more time to eat means less time to develop our brain further, so most likely we will only gradually getting smarter with that much food resources to feed our brain and maybe grow slightly taller by a few inch

technically they could, but like i said in my previous comment growing bigger body parts require a lot of nutrient and make our body bigger would mean we need to eat significanly more than we are normally, our body is a perfect match for our brain, BUT if human does evolve into a giant, they would probably become a little bit more dumb, since they favor big body to survive rather than better brains, tehy would probably act like a land version of Orca, they are smart.. for an animal but not so smart if compared to a human
What the hell?! I would LOVE to see some of these animals. God dammit, humans, why you gotta ruin everything :(
Yeah, why do we ruin everything?!
Well, what is probably the main cause of us ruining everything is that we only look out to make human lives better. Humans will cut down a forest, because the choices are made by people who doing that will only improve their lives. For instance, the air in china is so bad because the people who could cut down on coal use don't care if the atmosphere gets fucked. They think global warming won't affect their lifetime, so they don't do anything about it because it gets them more money. That is my take on the idea.
More like human values has changed (for the better?), traditionally we would not understand nor appreciate bio-diversity and wonders of evolution, but as we study more and grow wiser as a specie thanks to evident based scientific methods we learn to value those things that we were once take for granted.
Because instead of sharing and using our resources for the good of all, our economic system accumulate as much power and resources in the hands of few.
We don't look out to make people lives better. We struggle to keep living while great company owners play poker with economy. They only care about profit and we would have to really get out of our way to have a micro impact in changing anything. How many Island species have you saved last week? None? I think so.
Things only would change with a revolution but that's not gonna happen anytime soon

Freaking Satan Stork.
Also, I’m so glad you said Fossa correct, it upsets me when people say “Fow-sa” not “foosa”
your channel is missing something???
more subscribers.
great video as always man.
I'm missing subscribers. 😰
Love your videos! Especially the ones about paleontology and evolution. Another great example of this island phenomena are the Channel Islands off Southern California. There dwarf mammoths evolved from Columbia mammoths and there is a giant mouse too.
Thank you! I'm happy you enjoy them ;)
There's many amazing examples of island evolution around the world, I wouldn't be surprised if I missed a lot
Loved your video, man! I don't understand the dislikes (even though there are only two at this point). You're giving out free information on a fascinating biological subject coherently and you're super entertaining! How could anybody dislike this? You should totally make a Patreon though! Thanks for the awesome stuff brahh!
Oh and if you ever need any semi-realistic art stuff for your videos you can contact me at seve.paalanen@gmail.com!
Man, I miss dislikes...
Man, I miss dislikes...
That's funny, I saw that he'd uploaded this right after I'd done a school presentation on how animals on islands evolve differently.
This is the best video you've ever done! The waits between them are getting longer nowadays but this was well, well worth it! I have researched bits and pieces about a lot of the content you've included here and it is such an interesting topic! I saw a bit about Hateg Island in a documentary and thought it was like something from a Sci Fi novel! Hatzegopteryx swallowing sauropods whole, haha!
Looking forward to your next one!
Cheers!
Same.
I actually learned a lot a lot about islands from this video than in school.
hey trey just wanted to say really good video this time. Islands do play a very important role in the history of evolution. By the way i think that you should make a little series about every extinction event ever. Not just mass extinctions, but the small extinctions like the Jurassic and eocene extinctions. Some extinctions like these are very vaguely described, so if you could model the importance of these extinctions, how big we're they, that would be really helpful.
(By the way for a paleo profile A personal favorite of mine would be Paleo profile Hyaenodon)
This is reminding me of Pokemon Alola forms!
The Poke'Saurus Alolan forms are based on adaptation. But you are sort off on the right track
The Poke'Saurus Also Alolan exeggcutor
shortfuse 87 lmao giraffe looking ass
They are illustrating what he just said
So if for example parrots evolved to become flightless ground herbivores simply because there was no need of flight to escape predators
So does that mean if those flightless parrots still live will they evolve to fly again? Because there will be cats etc etc predators
That or become bigger
However we will never know now since we killed them
15:17 He looks like some guy's roommate.
this was the first vid of yours i ever saw, at the time i was really in a rough state and not doing well, but your videos were something that helped inspire me to learn more about the world we live in and try to make a better impact on the environment. I’ve been a big fan since this first video all the way back when i was in high school, graduating college soon and your videos still inspire me
Im a simple man , when I see trey . I watch him
Hungarian
Creepy guy
Me: I hope New Zealand is mentioned
New Zealand is the first island mentioned
YAY!!!
I'm genuinely mad about the extension of those birds in New Zeldand, it's so sad so so sad
So hobbits and those giant birds are not fictional species. Good to know
Gosh, I love your videos so much!! I used to do these types of research myself years ago but now with college and a job, I barely have time for anything anymore so it's a real blessing to be able to play one of your videos in the background while I'm doing chores or work :'3
When you upload a video it feels like Chistmas/my birthday/the day Saurian comes out!
I learned more from this video than i learn in school in a month. And im a Straight A student
GalaxyNote 7 same. And I'm Asian xD
Not sure if you meant college but it's also bad in college. These clowns aren't even teaching me what I want to learn. I'm so sick of it.
Yeah, school is just qualifications. Not actual knowledge, unfortunately. I've learned pretty much everything myself.
I agree. all the subjects can be soooooo interesting, but they either focus on an unimportant/boring part or take 3x as long as they should.
Alexander Knight Your black so what
It's ......beautifull *wipes a tear*
video of the decade at this point, remember watching this when it first came out. this video has shaped my life so much its insane
The kakopo sounds like a great bird to make domestic......
Too bad we didn't think about that.
@Chicken Tortilla YES
7:36 A species of parrot that has managed to converge evolve into to a predatory eagle parrot.
Now I've seen it all.
Trey, will you make a video about the recent rearrangement of the Dinosaur classification?
Trey, you explain it well.Just had to know how much I truly enjoy your work. Wish I had a teacher like you when I was a kid. Well done Sir, well done and thrice so.
That AT song really surprised me haha, really good video! just found your channel and I love it!
Incredible video, cool illustrations! I like that the pics you use actually say something and aren't just for the looks. 👌
Thank you! and no problem ;)
yeah finnaly a new vid , trey could you make a vid on the ice age
Islands are where the devs let the lower tier classes take over to see how well they would do in similar roles. Their also places used to test new potential metas in the game. Sadly most island meta gamers don’t make it when competing with their continental counterparts 😭
A tierzoo fan, eh?
trey you are an inspiration to me, your videos have inspired me to pursue science and develop a really strong fascination and interest in it thanks to these videos. Thank you
Hey Trey! I know mammology isn't your biggest field of expertise but I'd love to see you do an episode on the history of carnivorans and why they're so good at outcompeting other predators like sparassodonts and whatnot.
Great video! Trey has a talent to lay down all the facts perfectly. I'd love to see a video about Laramidia phenomena.
Oh boy, Trey uploaded!
Not so disappointed now, eh?
Well islands were always set on a lower difficulty, which enabled low tiers to rise to power. This is just the game catching up to them...
its alive, ITS ALIVE :D
Another great video! always so excited to see you've uploaded, I never get to watch them first thing though because all my roommates want to watch them together! We usually have some pretty good discussions afterwards. Keep it up :D
There used to be miniature humans on an island with giant lizards? I'd love to play a game as one of them. Fighting off giant monitor lizards with spears, I could have a tiny elephant friend, thatd be awesome!
*hears how some animals were bigger in Australia*
Explains why there's unholy giant bugs and stuff
ALSO WAIT, THERE IS ACTUALLY GIANT SWANS? I THOUGHT I MADE THAT UP, MY DINO WAS A SWAN THAT LIVED ON AN ISLAND WITH NO DINOSAURS, ALLOWING IT TO EVOLVE INTO TREX SIZED OMNIVORES OMG
Okay, so I need to write the rest of this for class tomorrow and then read a few pages in..huh.. *TREY UPLOADED A NEW VIDEO!* (Drops everything and puts on headphones) Educate me with your dulcet tones Lord Explainer
Trey: 12 vids a year
desert fox better than JonTron
Awesome that you mentioned Leachianus! I was wondering if you'd mention them as soon as I saw you made this. Another awesome video!
It's truly amazing how you create thesevideo's. It's like a lesson of a professor, I'm even taking notes while watching this. The fact that you can see that this is not just a interest you picked up knowledge over time and wanted to talk about, but that you actually took the time to research this subject. make it really worthwhile to watch, even for these longer types of video's.
just saying, good job, and keep it up.
Thanks man! I'm always happy to inform. I take great pride in my research and I'm really honored that other people respect that too. I really appreciate it ;)
Mini mammoths! Too cute :-)
This video has been out how long and it only has 4k likes!? We aren't doing our job. We gotta boost these rookie numbers guys!
You're like the Bill Nye of Biology
George Derswagger thats an insult to trey
Your channel keeps getting better over the years. Keep up the good work!
Thanks man!
im so glad you talked abt our kakapos. they're so cute, i did a tertiary studies report on them last year, they basically became too chunky to fly. bloody legends
also! you said about how there are only 100 or so more on the island, theyre actually not on our main island, im pretty sure theyre all on smaller seperate islands which are protected to try conserve them, and the islands went under strict pest control so there are no ferrets or cats etc on them:)
to Americans, don't call an emu a "eemoo"it's pronounced EEM-YOU
When parrots are eating your sheep, that's when you know nature screwed things up
Can u make a vid about the accuracy's and inaccuracy'a of ark survival evolved's Dino's and prehistoric mammals?
I think this is my favourite of your videos. So interesting! I was really interested about that small type of human you mentioned. Do you think you will do more videos on different prehistoric types of humans? I think that would be really interesting. :3
Fascinating. I remember Jerry Coyne talking about islands in Why Evolution is True. He said there are 2 different kinds of islands. Ones that broke off of the continent and others that formed I'm the middle of the sea. He said the continental islands has animals related to the ones on the continent and the oceanic islands are conspicuously devoid of terrestrial mammals, reptiles, amphibians and fresh water fish. But had plenty of bats, birds, insects, spiders, in other words, stuff that could get there. Bats, birds and even insects can be blown hundreds of miles by storms. And by using large nets dragged behind planes and ships, they found insects, pollen and such miles out to sea. That might make a cool video.
Very interesting
trey, make another vidio on crocodylomorphs. plz :)
It's annoying how so many animals went extinct because of humans.
It is but talking about it helps us learn from our mistakes, so it doesn’t happen again
If anything surrounded by ocean on all sides is an island then Pangea was an island
Xer Serpentine An island is a categorized by it being smaller than traditional landmasses. After a certain size threshold a landmass is no longer an island and becomes something greater. Pangaea, for example, is categorized as a super continent, seeing as it was all continents formed together.
Wow, I never really realized that kiwis are basically rat birds lmao. That was pretty mind blowing.
11:58 yeah I love the megalovania
