[@ComradeCorvus]

If we bring any animal back, I think the Dodo should be first. We were the main cause of their extinction both directly and indirectly. Apparently the Dodos, who had no natural predators, were unafraid of settlers to the point of trying to play with them. I have an alternate history scenario in my head where Dodos were taken more as pets rather than food, so different breeds of dodo arose, much like how dogs diversified. If some guy didnt decide to skip lunch that day, we couldve had "bird doggos". We were on the verge of greatness, we were THIS close!

[@SoulDelSol]

Good idea

[@elpito9326]

If dodos are brought back, Mauritius would have to clean the island up of invasive species before they're reintroduced, which is a monumental task, but it'd do a lot of good for the island's biodiversity

Sadly it is an illusion that backbreeding really could recreate an extinct animal. They just create knock-offs. But lets appreciate it even so because they preserve some rare and pristine genes while working their projects.

[@mr.anderson2241]

Yeah I was thinking the same about back breading, if you really think about it it’s no different than what people do with dogs, you’re not creating a new species as much as you are just creating a different version of the same animal. This theoretical quagga would need to also behave like a quagga and have some unique DNA, and it seems to be not that unless they somehow make a tightly controlled pack that somehow develops their own unique species?

[@Salted_Fysh]

Well, I'm not sure, but not necessarily? I think what you are essentially doing is breeding legacy genes of the previous species back into prominence. If the genetic profile of the two doggies species is close enough, the slight shift in prevalent genres might actually recreate the actual previous species.

[@alterbr33d]

Those are only perceived looks. The behavior and function could be totally different. Caribou and domesticated Reindeer look very similar, except Reindeer are a little smaller. Reindeer were European Caribou that were domesticated 2000 years ago. If Caribou went extinct, that doesn't mean Reindeer from Sweden that are bred to be bigger that are dropped off in Canada would do well, they behave very differently and wouldn't do so well in the wild. Or just because you start breeding big burly people doesn't mean you've created Neandethal kids.

What I think is interesting is we use machine learning and algorithms to model new DNA and then grow it out in a model to see what kind of combinations we come up with.

[@Laecy]

Even if we could assemble a complete DNA sequence, the epigenetic markers would be incoherent at best. There is evidence that imperfect methylation patterns are why we still struggle to produce healthy clones.

[@smugreptile6695]

@@Laecy Essentially we might be able to bring something back, only for the metabolism of an animal gene donor to kick in and starve the subject to death before we realize whats going on. Patching the DNA with other animals might give a stable genome, but the ramifications of all the biological factors of a multi-animal hybrid are almost endless. You might bring back a fast metabolism mammal, but if you had to add genes of say a reptile, or a mammal with a slow metabolism, then the odds of that animal surviving are low. And thats just Metabolism. There are a whole host of other issues with splicing genomes together.

[@davidschaftenaar6530]

Ahh there it is~ Some freakishly tall ice-age enthousiast let slip you were working on this ;) Interesting topic. I can't say I'm a fan of the backbreeding approach personally, selecting for appearance doesn't necessarily mean the look-a-like will match the extinct species in terms of behavior too. Selecting for behavior rather than appearance (the other way around) might be the better option if you ask me; There's an ongoing project in Russia with the aim of domesticating foxes - they've reported that their foxes are starting to not just act more like dogs, they are starting to look more and more like them too, even though that's not what the researchers are selecting them for. I think cloning is probably the more promising of the two approaches, especially combined with tools like CRISPR+CAS9. They seem to be focusing exclusively on the nuclear DNA though, which I think might be the reason for the health problems you see in many young cloned animals. Mitochondrial DNA codes for some important stuff... The encoded genes play an important role in metabolism, just to name one.

Cats, foxes, cane toads, scrubbers and rabbits ARE NOT DESTROYING australian ecosystems.. and Neither are Dingos! WE ARE tho when a new species come in an ecosystem, there are frictions at first but we know from looking at the fossil records that in the long run, it tends to produce more biodiversity than it has destroyed.. Give them 50 000 years.. And no, preserving what's left because of the actual biodiversity crisis isn't a good strategy at all on the long run, at least not from them; because unlike us, they can't destroy an ecosystem to the point of killing 99.9% of all life on it (like we do pretty much every time we settle somewhere or want to grow crops somewhere), they'll only kill off 2% at most and YES that's negligible considering how much the ecosystems can gain from their introduction on the long run..

Reminds me of a story about a futuristic amusement park where dinosaurs are brought to life through advanced cloning techniques. I call it "Billy and the Cloneasaurus."

Tropical Asian here. Cane toads are an invasive species here too. At least i havent seen ones as big as bullfrogs.

[@dodoxasaurus6904]

I think the problem is where would we put them, some of the ecosystems either are different or no longer exist/ don't have the capacity. Like the Dodo, which lived of the Island of Mauritius which only have 4% of the original forest left.

Mammoths would surly be great in siberia or canada and could help with the tundra plains and tasmanian tigers could also be a great part in their old homes but some others can truely make more harm than good

One factor that everyone seems to overlook on extinction / de-extinction is: Bionomes. I think micro extinctions are a thing that affect the macro world. Back breeding is like putting a body kit on a fierro and calling it a Porsche

[@paulinemarpaung2261]

Your right

[@Bajolzas]

when you breed zebras to look like quaggas, you get exactly that, a zebra that looks like a quagga, it will not be an actual quagga. with genetic engeneering it may end up closer to the real thing but stil...

[@FaustLimbusCompany]

Quaggas are just a type of Zebra though

[@semansco]

​@@FaustLimbusCompany The reverse-engineering of the zebra was done solely based on coloration. There were other genetic characteristics and adaptations that we were not taken into account. As it stands now, it is simply a zebra with quagga coloration. To make it clearer, there were other things besides coloration that made them quaggas, not just color.

[@FaustLimbusCompany]

@@semansco You raise a good point. But let's look at it from a different perspective; if were to someone reverse-engineer a dinosaur from a chicken embryo and it is still essentially a chicken but looks like a dinosaur, wouldn't people would still go out of their way to see it and call it a dinosaur? For most people, they'll pay to see something that fulfills their experience. There are people who care a lot for authenticity but there are more people who would simply settle for a substitute as long as it gives the same experience.

[@semansco]

@@FaustLimbusCompany Whether people would pay to see such a thing or believe that they are seeing a dinosaur resurrected from the past is their business. The chicken would be a modified chicken, not a dinosaur. That is the subject of this discussion. It was worthwhile science but does not achieve the aim we are after. We are hoping to bring back a species with all of its unique attributes from extinction. We understand that the animal they produced may look like a quagga but is not. Exactly what @bajolzas said above.

[@FaustLimbusCompany]

@@semansco All I'm saying is that if it might be impossible to bring back a 100% authentic species, people who aren't scientists will still be content with a replica as long as it's convincing.

I think it's our responsibility to bring back animals that we hunted down to extinction in the last 50-100 year. Or at least we should try to prevent species from dying out in the future.

[@renarddubois940]

no, not prevent species from dying out.. this is extremely dangerous and very very much not the right way to go about it.. bringing back species is fine but natural extinction need to happen so that new species can form out of competing for the ecological niches left behind.. it's important to think in ecological time, not politic and economic time.; For an invasive species to start producing more biodiversity than it has destroyed takes time, but we know it happens most of the time thanks to the fossil record.. what we need to do isn't prevent extinction but stop destroying the world, stop taking all the land for ourselves and stop controlling ecosystems and managing them to keep them orderly because they aren't supposed to be orderly and it's certainly not by being orderly and managed that they will be able to produce the diversity and strengths they need to produce to fix our mess..

[@hitenshah821]

Your videos have an extreme amount of detailing which can only be achieved by painstaking research. Your hard work literally shows at each minute of the video.

[@frankeneh-lf6fb]

Speaking of de extinction I would try to cross a red handfish with not so much spines and a red handfish with not enough red on it's body to get a smooth handfish. But I might need some other angler fish species maybe a frogfish or a coffinfish to get a smooth handfish
