Anything with wings? Like the only group more or less related to spiders, which has wings, are insects, and they are as related to spiders as fish are to humans, maybe learn some biology, it will certainly make a better less stressful life to not gear something impossible
Several years ago I spent a few weeks in the higher arctic (construction). Once I had a chance to go fishing with local residents (Inuits). They mentioned we must be careful not to cross with grizzly a bear. I was shocked - a grizzly at latitude 70 on an Arctic island?! But they said at their location now grizzlies outnumber polar bears by far! (~1:6) Amazing how they are making their dens to hibernate through long arctic winters having no trees.
It's not really surprising when you think about the origin of polar bears. They were brown bears that lived north when it was warmer and evolved into polar bears as the climate got colder.
We had Coyote/wolf mixes where I used to live. Smartest canines I've ever had the pleasure of dealing with. They weren't afraid of humans, just cautious around us. They traveled in groups of 3 (6 total) and hunted the local foxes and cats out before going after the deer. There was one in particular that would try to "sneakily" follow me along the river bank. I say that with quotations because the dingus was too big to hide in the bank grass lol
@@nickkerr5714 That is false. Coyotes that share their NC range with red wolves are sterilized to prevent breeding, but the hybrids pups are not typically harmed.
I'm surprised you didn't mention the coywolf. Also raccoons have been splitting into two species over the last few hundred years. The city raccoons are now faster in a drag race than their country cousins. Four-lane road crossings eliminated the slower ones from gene pool.
We're talking hunters - cowardly, messed up brains that think a good time is shooting animals. If they cared about ethics they wouldn't be doing it in the first place. There's quite often a hunter or farmer with a gun responsible for killing the last of a species after intruding on their ecosystem. And the many, many before it become extinct.
@@--Nath-- what about hunting to feed a family? Or killing an animal threatening your livelihood? Trophy hunting is stupid but the reasons I stated are absolutely acceptable.
@@drakemasterson9874 indeed, trophy hunting is total utter BS but hunting for the meat or safety is totally valid it checks my great grandfather list of reasons to kill, hunger and defense.
It truly is heartbreaking to learn about the habitat for polar bears. 😭 I imagine those poor animals are starving to death. No species should have to die like that. I really hope they find a way to survive.
The polar bears are thriving. They are not being pushed closer to extinction as this highly inaccurate clip states. There are more polar bears now as there is an abundance of food as the glaciers have retreated. The population is nearly tripled in 40years. This nature show is more fiction than fact. Climate change is very real. Humans need to stop their waste. But please, this show is off the hook with made up facts.
It reminds me of that episode of the Simpsons were the bees are dying off so they crossbreed them with another species of bee to make super bees that can survive under any conditions.
There are also other hybrids showing up in other places. In northern Ontario we commonly see crosses with wolves and coyotes. We call them coywolf. They have the opportunistic and inquiry of a coyotes and the bite force and strength of a wolf.
2:02 mins in, I can say that I think the reason why animals are hybridizing is to share more positive traits across environments since humans are taking more of their natural habitats. Like the best of both worlds.
Sorry, but who ever is responsible for naming the hybrid species, please, PLEASE keep working on those names and put in some effort... A pizzly must not stay...
@@batfurs3001 Sometimes they are seen as different species, sometimes subspecies. Dosen't really matter. Different dog breeds could also be argued are, sometimes, different species. It's all just semantics. Cats though are genetically very similar to wild cats. People just fed them to have them hang around and keep vermin away. Dogs were bred for specific tasks, such as standig guard, herding sheep and so on. They are also far larger and are kept closer, so you can't have them be as aggressive and so on.
@@batfurs3001 But I am betting not distinct enough that any hybrids are sterile am I right? Plus Im pretty sure Coywolves count as much as the Pizzly and Grolar bears.
@@batfurs3001 Domestic dogs are literally the same species as wolves which is Canis lupus. Domestic dogs are sometimes known as Canis lupus familiaris, which is still the same species, just a subspecies of Canis lupus. Edit: Over 30 subspecies of Canis lupus exist, most of those being Wolves but also include Dingos and Dogs.
They are but its not because they're not having enough offspring... its due to habitat loss from the polar ice melting. Letting them breed more won't save the species when their hunting grounds are gone...

@@davidhenningson4782 that bit about Bezos 😒 he should pay fair share of taxes instead of being treated like some monopolizing god. But as far "we're still here," until we're not. Plenty of animals have gone extinct and if humans don't take better care, it's only a matter of time!
The age of internet is truely a wonderful era. Hey, if you like animals facts I also make animal and science videos. They’re no where as good as Goliath RU-vid channels like this. But over time they will and are improving.
@@bananawitchcraft they could be making so much more if they used their production team to make a documentary for a mega company. But yes. Capitalism works out sometimes.
Should be obvious. After all, wolves and dogs remain capable of interbreeding even though we tend to treat them as different "species". Despite the fact that many dogs have been artificially bred into radically different forms from their common ancestors with modern wolves.
But half-wolves are a Russian roulette since you can never know for sure how much and what of wolf the hybrid got... saying wolf or "good boy" behavioural traits? wanna bet with your hit points?
@@nosotrosloslobosestamosreg4115 - Having had some very large and aggressive GSDs, I think it can be managed so long as you don't assume that a wolfdog is suitable for urban or suburban life.
@@daniels7907 wolfdog are for outdoors and strong willed people. Russians are breding wolfdogs but selecting more dog like behaviours. Anyway, other issue with hybrids is possible loss of very specific allels.
@@daniels7907 Russians are breeding wolfdogs, but selecting dog like behaviours for that very same reason. Other issue with hybrids is the loss of particular traits associated to recessive genes, and look for the case of hybridization amnog african and indian lions.
The difference is just... this one is a nature success. There's many "defect" hybrid cat and dog killed around the world as a result of producing mass "cute" pets for buyers. Call me hypocrite but I will eat hybrid chicken but not hybrid dog, cat or bear.
What’s even worse is they did an interview with the guy that killed the Grolar Bear in 2006 and he says he doesn’t even regret it and says that he’s proud to be the only person in the world to have it stuffed as a trophy in his house.
There have been others in the past, just that no one thought to DNA test them until recently, as DNA testing wasn't available when they died. Polar bears are very closely related to brown/ grizzly bears. In fact genetically they are just a more specialized version of the brown/ grizzly bear.
Maybe breeding like this is how evolution always has been. First, a species evolves into two as they split paths Later, somehow and sometime those two species meet again and breed Then a new species adapted to new things appears, and then it all repeats again.
Yeah, makes sense. Kinda frustrating people are making a problem out of that.. I mean, let nature be. They are trying to adapt to our shitty way of living so let them fuck whoever they want xD
your hypothesis seems logical, tho I must add some detail to it to make it more convincing:- 1- changes in climate and nature seperate two groups of the same specie, and they evolve into slightly different species over a period of thousands to millions of years. 2- climate change reconnect their isolated areas, and they interbreed, creating a very diverse hybrid specie. 3- climate seperates them again, the hybrid specie adapt to their enviroment. and the cycle continues. ps: I am not a scientist of any sort, you can take all the credit, as I'd prefer to not be called an "Evolutionary Biologist" where I live (the middle east).
@@creedorian Climate change isn't new at all. How do you think Polar bears came into existence in the first place? They are an offshoot species of the brown bear that diverged 100k+ years ago when the arctic got cold.
The first letter of the father species is the first letter of the hybrid name If the father is a polar bear and the mother is a grizzly then it’s a pizzly Is the father is a grizzly and the mother is a polar bear then it’s a grolar bear This rule goes for almost all hybrids
Pizzly and Grolar bears have two different body plans. The Pizzly has the body plan of a Polar bear, so it should have a close to the same lifestyle as the Polar bear. While the Grolar Bear has the body plan of a Grizzly, so it should have a lifestyle similar to that of a Grizzly. Both may be better suited to the Artic/sub-artic all the way down to more temperate climates. With the Pizzly staying more north while the Grolar moving further south. At least if the body plan is taken into account and that translates over to them, taking after one parent more than the other in their diets.
You're misusing 'body plan', a term already utilised in zoology regarding the morphology of organisms more generally. Here, you are referring to variation of specific characteristics of their morphology.

Actually it is possible for a mule to have offspring albeit rare. The latest I've heard of was in Colorado, and yes it was proven genetically. Thought to occur when by astronomical chance a viable gamete is formed during meiosis.
Polar bears weren't even going extinct, along with a lot of other animals they said we're going extinct and then they find out they've just haven't been seeing them. People are wondering if the ivory billed woodpecker is still around. I wouldn't be surprised if our government has their hand in these organizations asking for donations because of climate change, or Marxist are just trying to drain us of our money.. has nothing to do with actual animals going extinct. I really don't even know if it's a smart thing to do to keep animals from going extinct when maybe it was God's plan for them to go extinct. Now if there's something that we've directly done that impacted them, I can understand us doing something but if it's nature's cause, it needs to be left alone.

I think it's the government doing these hybrid experiments, releasing them into the wild. Could it play a part in the gain of function research? 🤔 We have coywolves here in Michigan. How? I get it, upper peninsula has wolves, very few sightings after the bridge but what? Wolves and coyotes mating and then migrating bc they aren't your typical wolf or coyote? I don't know.

No their numbers are BOOMING in Canada. They have become monsterous pests and have driven each other further and further toward people because they are territorial and eat a lot.
It's a fine line. We want to save the species, but when they hang around human territory too much... Polar bears are extremely dangerous. Most animals will not actively hunt humans, but polar bears very much will.

I find myself addicted to Real Science, Real engineering, PBS Spacetime, PBS Eons, and similar RU-vid channels. I am working on my second degree and still managed to learn more from such channels than I ever have in school. It is always refreshing to see that there are always thousands upon thousands of people who love learning and understanding how things work as much as I do. Sadly, many students attending my university only seem to be here because college is just something people do. I too have deleted social media from my phone and have not watched actual TV in years. Those media sources only seem to emphasize the flaws of humanity, over and over. As a kid in the early 2000's, I preferred reading encyclopedias and textbooks over watching whatever my piers were into at the time. Channels like this have made my hunger for knowledge much more convenient to satiate. Thank you.
I remember that episode in Ba Sing Se when the king holds a birthday party for his pet bear and then they guess if it's platypus bear, skunk bear or armadillo bear and it turns out the pet is only a bear. Knowing that they seem kinda confused as if normal animal is very rare and hybrid animals are a lot more common. Even toph comment that it is weird.
Speaking of hybrids we have mice that are now the size of large rats--12 inches+ nose to tail. Having raised rats years ago, my experience is that rats are very hostile to mice so I have no idea how they could have mated together.
One family I knew had a rabbit hutch in their backyard and one morning the dad was going to work and looked in. He saw the kid’s rabbits were covered in blood. He called work and told them he had to see to the rabbits before his kids saw them. He thought they were injured. He pulled them out and brought them to a sink in the basement to shampoo them and examined them. He found no injuries on them. Inside the hutch were dead rats. The rabbits tore them apart. Also when I went to college they had an animal lab. I went in one day and a student was sitting with a long haired animal on his lap brushing him. The animal was white, brown and black. I said what a pretty cat. The student said that was no cat. He lifted up the tail and said this is a rat. It was so big it covered his whole lap. I saw a smaller one of those in the country once and said if they all had this hair and were so pretty less people would dislike them.
I would have never known about evolution or any of this if it wasn't for the internet and content creators like you. Thank you. It's such a High quality content
Find out, the video was all about evolution. It even mentioned speciation. Polar bears and grizzly bears can hybridize because they evolved from a common ancestor 150,000 years ago, horses and donkeys can hybridize but only produce infertile offspring because they diverged 4 million years ago and have been evolving separately for 4 millions years. That’s what the video said, not sure how you missed that.
@@Randomhandlename So you completely ignore what I said while at the same time misunderstanding the whole video. Okay. And that's not what evolution is.
@@Djarms67 usually its the male liger hybrid is sterile, but the females ligerless are fertile. Also documented incidence of female mules sometimes fertile, while male mules are totally sterile
@@Djarms67 as it seems Neanderthal/Homo Sapiens offspring wasn't infertile and probably interbred with other Neanderthals and Homo Sapiens and we still carry their DNA in us (people from Southern Europe up to 4%). So the offspring either wasn't infertile, or interbreeding was much more common that scientists thought
I hope scientist are capturing a variety of endangered species DNA samples. Since stopping extinction of many species seems impossible, given the size of the problem and human attitude, perhaps we'll be able to revive these species in the future. Hopefully, responsibly.
It’s sad that species are lost. But you can’t keep everything “pure” and alive. The last time we tried to keep something “pure”, it resulted in sick breeds like dogs that can’t breathe or have hip problems. That doesn’t mean we shouldn’t do our best, we should just be aware of that and hope there are no other problems we can’t think of. Some zoos try to keep animals for conservation. It’s a little better than keeping their DNA because nature is evolving and living things need constantly to adapt. I hope they will succeed in having enclosures as natural as possible. Sadly not all zoos do it well. Hybrids are something natural and an adaption to the environment, it’s happening all the time. Nature finds a way and will be fine in the end, humans less.
I wouldn’t worry too much. While it is sad ti see species become extinct. Scientists have collected thousands upon thousands of dna samples from teeth, bones, mitochondria, tissue and organs from each species of currently known animals that are in danger of becoming extinct.
@Urusovite The big problem is that Nature does not follow its normal cycles anymore given the huge impact of human activity for centuries. The imbalance is clear and the results will be unprecedented.
A lot of prehistoric animals look like hybrids and the current wild animals we have roaming the planet look like isolated species that adapted and specialized to their geographic location.
Just a thought watching the video (great video as always), when talking about the time since two species diverged, wouldn't it be interesting to add an estimated amount of generations? Because I suppose 150k years of evolution to a Drosophila isn't the same as to a polar bear.
@@processedpotato9378 bad ass? nah man, it's cowardly bullshit. go hunt bears with your knuckles and a jack knife, make it a fair contest, then I'll give the person a "that's bad ass" and totally mean it haha hiding in a tree and deading a beautiful, gorgeous beast like a bear with the break of a trigger is, and always will be, cowardly, disgraceful, bullshit. In my (oh so incredibly) humble opinion.... obviously.
I assume you think their endangered, but in reality Polar bears numbers are growing and have been for many years. The only reason they were even endangered to begin with was due to over hunting and after regulation their numbers have bounced back to vulnerable. Global warming has had no effect on them, the activist were just lying, which they do a lot, and then have the gall to complain about how some people won't believe in climate change. YOUR THE REASON DAMMIT! STOP LYING! YOU ARE KILLING YOUR OWN CAUSE! Polar bears are supper predators and, despite what video says, are having no visible trouble. It's the hybridization that is the real threat to them, and that IS climate changes fault because its letting grizzles into places they couldn't live in before. If you have trouble believing me, considered this; the pizzily in this video was found in polar bear territory, so the migratory parent was likely the grizzly parent not the polar bear one.
I rescued a cat 🐈 my grandmother took in as a pet. It kept Getting abnormaly large very fast. After taking it to the vet she found out it was half Bob cat.
It is rare that a video such as this teaches me of a new type of animal as I have spent a lot of time time researching. Especially my favorites; cetaceans! So I was thrilled to hear about these hybrid Narwhal/Beluga. Thank you for the excellent video!
For those wondering: hybrids are named based on their parents. The father species (lion) & the mother species (tiger) is what results in the name like liger or narluga or pizzly bear. They're not just given silly names for no reason.
Lion + tiger = Liger Narwhal + Beluga = Narluga Grizzly + Polar = Pizzly Am i the only one that saw the anomaly here...? P/S: you really don't think it should be Grizzlar...?

My cousin has a hybrid snake. He took a male corn snake and mated it with a female black ratsnake. The resulting mixes were kind of strange looking and he kept 1 of them and sold the rest but he specifically sold them as hybrids. I don't know if they would be considered true hybrids though because a corn snake is technically a kind of ratsnake as well. Different ratsnakes and corn snakes have been known to mate in the wild occasionally as well.
I have always wondered if you could create a mamba hybrid if you mated a green and a black. Despite my efforts I’ve never found a definitive answer. If you speak to your cousin, maybe you’d ask for me? Cheers
hybrids is what helps with evolution at times, I mean, look at humans. We mixed with Neanderthals, Denisovans, and two other unnamed hominids. The Pizzly is just a start of a new line of bear that will generically diverge into a new species. Honestly, I think hybridism is over looked ALOT of the history of evolution. So doesn't that mean Pizzly would have 'two' common ancestors Domesticated Arctic dogs have 1.4% taiymer wolf in their genetics, were other dogs dont. Wolfdogs are hybrids, some people try to argue they are the same and not a hybrid. It is, just like a Coydog. Not to mention the constant hybridization of plants. I have seen photos of a tarantula hybrid of p.Irminia and p.Cambridgei, though it was sterile. Actually, now that I remember, hybridization was a HUGE touchy subject in the tarantula hobby. lol

Thank you - Great episode - Perfect examples of how during different times of existence it's important to be able to be flexible - becoming a generalist and able to take advantage of anything that exists, in order to survive, while at times becoming a specialist for the purpose of differentiation and survival. This is both at a macro level (over long periods of time as animals adapt within their species to survive) as well as micro-level (with the individual human having to redefine our own skills to become more specialized as we search to find a career that will span more than just a couple of years). Change is constant - Thank you Real Science

Coywolves (Coyote x wolves) tend to pop up as well, especially along the geographical edges where the two populations intermingle. In fact, a decent portion of red and eastern wolves have coyote genetics. This makes Coywolves larger than coyotes, smaller than wolves, and they form more cohesive social units. I live in the Great Lakes region, so it strikes me as interesting just how many hybrids exist.
@@willthelucky9582 You can use Life. It's a better term that leads to no confusion (especially since some people consider humans, or anything related to humans, apart from nature).

I love science, and this was a fascinating video. When you got to the African cichlid portion and the diversity in the Rift lakes of East Africa, I was hooked!
i found this video very eye opening because my understanding of how species come about, is simply that it could only happen after thousands if not millsions of years.
While it generally does. Hybridization is one of the many ways new species form and just part of evolution. Look up the story of big bird. A hybrid between 2 Galapagos finch species. It’s actually a really interesting story. Btw I also make educational animals videos. Try watching one :)

It's still diverging. The new species is a new different kind of species, with different traits. Speciation through hybridization can occur on the boundaries between two different environments, and the resulting species finds a niche it can occupy that wasn't by the former parental species (diverse geography leading to hybridization). Although it does happen a lot easier in smaller regions or environments, like recently in the Galapagos, we found a new species that came through hybridization (why is it a new species? its population is maintained stable by the hybrids reproducing with each other.)
