Releasing Chinese giant salamanders back into the wild sounds like a good idea, but it's causing problems for the salamanders and for our understanding of what a species even is.

For 5 years in the early 1990s, I lived in the NW part of Kyoto, a short bicycle ride from the Kiyotake River. This tributary of the Hozu River is a clear, fast flowing mountain stream with numerous cascades and deep pools. It is also ideal habitat for the Japanese giant salamander, a species closely related to the Chinese giant salamander featured in your video. The river supports a healthy breeding population of giant salamanders, and large individuals could routinely be spotted while diving with a mask and snorkel in the deep pools. The largest known salamander in the section of river where I used to hang out was 154cm, around 5 ft. Thanks for reminding me of an earlier, fun time of my life.

While it may still be worth trying to save the individual Chinese Giant Salamander populations, if that turns out to be impossible, then the hybrids likely will at least fill the same ecological role as their ancestors without too much trouble. Obviously its never good to lose so much genetic variation, but in this specific case, we'd still have the opportunity to fill that ecological role with a functionally equivalent animal, which can at least prevent a trophic cascade

@davidegaruti2582 2 года назад

Yeah , also they might re adapt to get the same caracteristics of the previus morphs : it would be like reintroducing husky/german shepard/golden retriver/bloodhound half breeds in siberia in the place of siberian husky , Eventually over the generations the genes of the husky would come to prevail , I know this isn't a perfect example and dog breeds are different than these guys , it's an example for natural selection operating at the genes leves

@oliverwilson11 2 года назад

Genetic variation isn't lost by releasing farmed animals. In fact more of it can be retained because instead of small isolated populations dying out they can find mates and their genes can survive. What would be lost is the segregation between genetically distinct populations.

@kyrab7914 2 года назад

My thoughts as well. Bringing back a species from extinction means either literally genetically piecing it back together and inserting that egg into a host animal, or an animal bred to be like the former animal, iirc from... One of the scishow channels. I know losing species isn't great, and genetic variation good. But we didn't know, and at least the hybrids are made from native animals instead of invasive ones?

@Beryllahawk 2 года назад

I could hear the mild headache at the "life finds a way" bit, haha Fascinating that the species are so genetically similar - and it makes a kind of sense that there are species (or sub species) adapted to specific river systems. Each river probably has a really distinct character - not just its ecosystem but the geological characteristics too, right? Hopefully, we humans will untangle the mess in some way that allows us to preserve diversity and also not cause anybody to go hungry...

@sampagano205 2 года назад

One point that I think also comes into this is also how important saving individual species is vs making sure the group survives at all. Is it the actual lineages that you prioritize or the fact that there are animals doing what the giant salamander does in it's environment, and the specific lineage matters less.

I am no expert but I would consider them as overall as one species and each "sub-species" contributing to its overall biodiversity. How well adapted they are is also a variable with the biodiversity. Sort of a weird sort of sum of adaptation * genetic distinctiveness. Say that we wouldn't try to breed say albino giant salamanders just to be more distinct. There wouldn't be a niche for them and they would soon die out in nature anyway. But if we discovered albino giant salamanders in underwater cave systems they would be good for biodiversity.

I feel like interbreeding between these guys is a good thing overall. More genetic diversity is actually helpful for species to thrive. Maybe we won't have 5 to 8 slightly different species of giant salamanders anymore, but we'll have 1 extremely successful species that combines the best traits of all of them. It's not quite natural evolution, but its basically evolution anyway

@alonealien1474 2 года назад

I don't understand this at an expert level so can't say whether I'm right or wrong, but on a basic level I agree with your reasoning. Like if breeding and creating fertile offspring isn't an issue, then is purity of species a thing we should be concerned about?

@pyrogamerpredator1016 2 года назад

@wezul 2 года назад

The problem with that is, the one homogenous species would be really well adapted to _current conditions_. If (and when) conditions change, they may not be well adapted to the new way of things, and may have lost the genetic diversity that would allow them to adapt. Thus, they would ultimately die out. This is why genetic diversity is so important: for the ability to adapt to new changes, which will surely come, given enough time.

@raccoontrashpanda1467 2 года назад

Problem is if there is only 1 species instead of 8+ then one disease that is particularly deadly to that one species could wipe them all out. 8+ species would have a much better chance of some resisting it.

I thought fertile offspring at all defined species and fertile offspring in nature defined subspecies. But then there's also species complex (or was it ring species?) weirdness where every member can interbreed with some other member but not all members can interbreed with each other, but I'm willing to chalk that up to incomplete speciation.

@Great_Olaf5 2 года назад

Ring and chain species are usually very geographical. You get them around large mountains, where various subspecies that are directly adjacent to each other can interbreed, but if you go too far down the chain, they can't. It's not a random mixture of one's which can and can't, they're divided up by geography, and even if they're brought together they can't breed, either at all or with fertile offspring.

@MLeoDaalder 2 года назад

A series of species of gulls in europe/scadinavia/iceland/greenland/US if I remember by scishow correctly. Where one end of the ring/chain _can't_ interbreed with the other end, yet they are geographically connected (share nesting sites) but every other link/pair of species in the ring/chain _can_ interbreed.

@nidohime6233 2 года назад

Just by looking at some domestic house cat hybrids. Thanks for the video keep them coming and the weird are the better.

@Ezullof 2 года назад

Honestly, most debates about species/subspecies definitions miss the point. Which is - what do we use those concepts for? And the thing is - it depends. Sometimes we need to use a definition, other times we need another. When your goal is preservation, it's important to know whether two individuals will be able to breed to produce fertile offsprings. But when you're researching about evolutionary biology, you need to use a definition that integrates intraspecies diversity in a different way. Paleonthology? Interbreeding cannot even be a factor, it's all anatomy and genetics. etc. And technically that's what researchers do. When they are using the concept of species, they are often defining it at the beginning on their paper, depending on their needs. So overall the debate about the definition of what a species is, is mostly a philosophy of sciences debate.

@kitgodsey 2 года назад

The caveat introduced in the video (hybridization in nature) saves BSC for me a bit, since it pulls out that human element of "we put a lion and tiger together and got a liger!" So, going off grizzly/polar bear hybrids, the main drive of that seems to be polar bears searching in vain for more space, while grizzlies can move further north due to warming weather, giving rise to hybrids when they meet. But because climate change and habitat loss is caused by humans, it's safe to say these species likely wouldn't have met and been able to interbreed in the first place. Personally I'm still not the biggest fan of BSC, but it's relatively easy to teach at a large scale and at least works in separating stuff to family/genera (mostly)

The fertile offpsring definition makes me think of Australian dingos. People disagree about whether they're a separate species or just a breed of dog. Dingos separated from dogs 10s of thousands of years ago, but can still interbreed with regular dogs. Which is also why "purebred" dingos are becoming more and more rare as they're often interbreeding with dogs (often, but not always, feral ones). It's very common for dogs in Australia, especially in more rural areas, to have some dingo in them.

@kitgodsey 2 года назад

Last summer I worked with two bird species that are *definitely* different species (Neslon's Sparrow & Saltmarsh Sparrow) since their breeding behavior and regionalism separate them, but they also hybridize so much that within their small band of hybrid zone we aren't sure how much NELS are in the SALS and vice-versa It's even crazier because Nelson's Sparrows are inland (Great Plains) marsh birds and not as well adapted to saltmarsh conditions, but somehow they found their way to the North Atlantic and set up a big enough breeding population to then hybridize!

@kitgodsey 2 года назад

When it comes to conservation this is a big issue, since NELS are listed as Least Concern, but SALS are Endangered. But like Hank said, where does a species stop or begin? In this case it's pretty clear they're distinct species who happen to have a foggy hybrid zone, but the question still stands. (And let's not get started on the Golden-winged vs Blue-winged warbler debates)

@j.e.h.648 2 года назад

There are also crossbreeds of species in the wild. Especially in river fishes it’s common that in the crosssections of different habitat the different species interbreed sometimes and develop new features sometimes not know in either species. A lot of those fish are fertile but usually their features breed out after a couple of generations with one of its parental species.

With regards to our own species, paleoanthropologists now argue for a pan-african origin for Homo sapiens. Essentially, we came from a mixing of all the archaic human populations in Africa that could interbreed. What complicates this further is that the first fossil skull recognised as Homo sapiens does not actual resemble a modern human skull, possessing a massive brow ridge, but it was on to line that would become us eventually. This is all to say there's no 1 single point where Homp sapiens emerged out of this interbreeding madness between African populations.

@GenaTrius 2 года назад

Take the species question out of the equation and look at what's happening. You've got an animal that's easily grouped by a shared bauplan and ecological niche that's had very little gene flow between its populations for a very long time. And now a pyramid scheme and government action has suddenly allowed those long isolated populations to randomly interbreed, and they've been successful in doing so. Some individuals might die when introduced to an area that doesn't quite meet their needs, but now that they're being farmed there's plenty more and some of them will. It also doesn't seem very likely that they're going to act like invasive species when they're being reintroduced to the original native range of creatures that are phenotypically nigh identical to them. Overall, and once again ignoring the species question, this is probably a pretty good thing for remarkably large salamanders from China.

The question is which will prove more beneficial - the genes specific to each “pure” species of salamander that gets lost in hybridization, or, the various genes from all the different salamanders that get introduced during hybridization. There is only 1 factor that is true, the Habitat has, and will continue to, change. Habitat Specific Traits will probably be more detrimental than beneficial. In the long run, diverse genes in the hybrid populations, might just be what the salamanders need to ultimately survive.

I volunteer to host some in my pond. As long as it doesn't try and eat my dogs.

This episode made me think. What makes pizzly bears so different from other hybrid animals that they can breed?

@Zarzar22 2 года назад

So basically they were doing their best to evolve into separate distinct species in their niche environments and we caught them and tossed them all together to destroy all of their progress :'(

That would be seriously sick if they breed it a bunch of tigers and lions together and then they released a bunch of ligers back onto the African continent. Totally awesome dude

These animals are so cool! I kind of want one as a pet. I'll never do it, but I want one, lol.

We actually had this come up in my biology college course they had changed the definition in the book that year so I ended up learning the wrong one because I was using last years book the professor was cool about it though and didn't count it off

So basically a mule is a normal horse brought together by 2 weird horses that adapted to different environments

@barrybarlowe5640 Год назад

Actually sounds like a good thing. Not that they're endangered, but they can interbreed. Strengthen the species. This guy seems to be a "Everything must forever remain unchanging!" Short sighted in my opinion.

I literally had someone a few years ago down in Chinatown when I was down in the back alleys try to sell me one of these huge ass things I didn't know what the hell it was it just look like a giant newt then come to find out later on that that was a Chinese giant salamander I didn't realize how endangered they were

@maylianong8182 2 года назад

reminds me of blue gill and sun gill fish hybridization .

@Charlie._.Niron22 2 года назад

Couldn't we call the species of Chinese Salamanders that are found in the different rivers a Subspecies and Depending on the Genetic and Morphological differences between the Japanese and Chinese Salamanders we could classify them as Either Subspecies or just a full-blown Species right? Like how we call the Asian Elephant species that are found in Sri Lanka and India are Subspecies but the ones found all the way in Myanmar are considered as the same Indian Elephant subspecies or Am I missing something important?

I think the important question here that is weighing on everybody's mind is, "Are they delicious?"

Yeah Word. (World Typo.)

@theflyingdutchguy9870 2 года назад

if something is the same species when they can hybridize. then there would be a lit less species. such as the rhino and gaboon viper. i think it should ciunt different for different groupzls. because something like an amphibian can diversivy into other species a lot faster than something like a mammal.

A Tiger and a Lion can interbreed I will never call them the same species

@charlieewing1810 11 месяцев назад

Is the major difference going to be something like pigmentation or lactose tolerance we see in humans, making it one species with generationally selected genes for their ecosystem, but still genetically compatible with their cousins a few rivers over?

I like you about as much as mike on that chapter. Which is a lot btw

@marcwhittle9810 11 месяцев назад

No such thing as an endangered hybrid and therefore no CITES listing is possible for hybrid Chinese Giant Salamanders opening up the possibility of an unregulated international trade as has occurred with some salamanders such as the hybridization of Ambystoma andersoni with Ambystoma mexicanum as well as with some hybridization of Crocodilians

@kylestanley7843 2 года назад

This beast doesn't really strike me as all that bizarre. Its history was fascinating as well as the discussions that bubbled up with it, but really... it's just a salamander that's big and sorta goofy looking.

@apocalypse487 2 года назад

What if salamanders have races?

@bookworm3005 2 года назад

OK so these salamanders might be different species, but a chihuahua, a great dane, and a pug are all one species??

@brandondavidson4085 Год назад

That brings up a good point about humans. Can ancient humans who interbred be considered the same species, since modern humans have Neanderthal, Homo Erectus, and Denisovan DNA?

@SuperZombieFanatic 2 года назад

Oh this is very similar to the problem with tarantulas; example being Mexican Redknee tarantulas (hamorii and smithii)

@marcob1729 День назад

just because two animals are separated by a river that they can’t cross, they shouldn’t be different species. That’s ridiculous lol

@sweithshetty9463 2 года назад

Well I guess that's the case with all other animals not just giant salamanders. In the past too interbreeding among different so called "species" is pretty common as common as in present

@sciencegremlin8307 20 дней назад

Do oceans count as physical barriers? Because if so then before ocean travel was possible between NA and Europe/Asia would North American humans and European/Asian humans be different species? Only to be considered the same species again once transoceanic travel between the two areas was established?
