Maned wolves are mythical creatures lol. Absolutely stunning animals. Was lucky enough to see then feeding at Yorkshire Wildlife Park. I love all dogs but these are up there as one of my favourite animals, alongside African wild dogs. Also damn we really took out Falkland's wolf while they were still young.

[@robertgotschall1246]

Great topic, thanks. Just one caveat about the Falklands Wolf. That they appeared during the Glacial Maximum may be significant. The Antarctic Ice Sheets could have extended that far north. But this was also the time of a huge lowering of sea level. Maps of that period show the Falkland Islands actually connected to South America by a land bridge, much like Berengia in the northern hemisphere. They would have been cut off when sea level rose.

[@AnnaMarianne]

If there was as a land bridge between the Falkland Islands and the mainland, more than just the Falkland Wolf would have colonized the islands. In the very least, there would be native rodents

[@nemanjastanimirovic155]

[@dr.polaris6423]

Thanks!

[@DraptorRonin]

Thank you for mentioning the Fuegian Dog! It's a shame that there are no living ones left tho...

[@Reyma777]

It may have been systematically exterminated by colonist and missionaries. Unfortunately, European colonization efforts caused loss of artifacts, languages and other cultural aspects in Indigenous communities. Disease brought by Domestic Dogs were probably a factor in the extinction of Fuegian Dog aswell.

[@RCSVirginia]

DraptorRonin I wonder if a controlled experiment with the Culpeo in either Chile or Argentina along the lines of Dmitry Belyayev's experiments with Silver Foxes in Russia could recreate the Fuegian Dog. The researchers could work to not just establish tameness and toleration of humans over generations, but, also, trainability and cooperation with people.

[@andythegoatman694]

Thank you for saying every habitable continent instead of 'every continent except Antarctica' that gets old also thanks for the video these guys catch my interest

[@slappy8941]

Imagine what the animals of the Americas would look like if the continents had never been connected to Asia or each other.

[@AnnaMarianne]

The animals of Afro-Eurasia would look very different then as well. We would have no horses, donkeys, dogs or camels in the Old World. How would human cultures have turned up then?

So if this group of canids had North American history (evolutionary wise), would they thrive in North American habitats (especially Florida) today (more so if certain environmental and climatic changes happened differently)?

[@Mr_G.B.]

Kinda impossible to say definitely but in my Opinion, Nah.

As I posted below in reply to DraptorRonin: "I wonder if a controlled experiment with the Culpeo in either Chile or Argentina along the lines of Dmitry Belyayev's experiments with Silver Foxes in Russia could recreate the Fuegian Dog. The researchers could work to not just establish tameness and toleration of humans over generations, but, also, trainability and cooperation with people."

[@N0sf3r4tuR1s3n]

I've often wondered if we could domesticate coyotes. The experiments Dr. Belyayev did with foxes are quite interesting, that's for sure- hell he not only selected for tameness but another group for aggression, genetic analysis of both groups could of course help identify genes associated with either trait. But your idea about applying this to the Culpeo is also quite interesting, maybe they wouldn't be entirely the same as the Fuegian Dog but close enough and they will properly fill that hole in the ecosystem. Considering that removing native species from an ecosystem is like pulling out Jenga blocks, their absence has probably caused effects that should be remedied.

[@RCSVirginia]

@@N0sf3r4tuR1s3n I cannot recall in which US state it was located, but there was an excavation of an ancient American Indian village that discovered something interesting. Amongst other items, there were found the bones of domesticated "dogs." When closely examined, it turned out that they were descended from coyotes and were not typical Indian dogs at all. So, this did happen at least once.

[@RCSVirginia]

@@N0sf3r4tuR1s3n The Culpeo, the ancestral source of the Fuegian Dog, is still extant and plays the role in the environment, hunting smaller animals, that it always has done. Recreating the Yahgan Dog would be aimed at making a totally domesticated animal. It could start with Dr. Dmitry Belyayev's selection of those with reduced flight response and move on to the ability to be trained. Achieving full domestication would be important because if these "dogs" started attacking people or other animals, the public would likely demand that they be destroyed. Done properly, they could become a symbol and source of pride for the people of Argentina and Chile, as well as the descendants of the Yahgan people themselves.

[@N0sf3r4tuR1s3n]

@@RCSVirginia hmm, well I seem to remember reading in an encyclopedia about dogs years ago that South American tribes domesticated like 3 kinds of "foxes" before European settlers moved in, so the idea that coyotes haven't been domesticated, or the Yaghan dog, well they apparently did. After all, the domestication of dogs from wolves was largely based on the pack orientation of wolves and that would apply to these closely related species. And I definitely agree that Yaghan dogs would have that added protection of Chilean and Argentinan pride- they'd consider them a cultural heritage probably. Yet another win for those countries on the international stage and I'm all for it, they've accomplished some interesting things so far and this proposal would be yet another accomplishment for them.

[@carlorielmendez6505]

This made me realize, on ground, hypercarnivores are either solitary megafauna that never reached sizes of the largest herbivores of their ecosystems, or mid-sized pack hunters. It seems to be the case with the seas as well like how whales are filter feeders but killer whales are pack hunters that are just a fraction of the size of baleen whales. Are there huge filter feeders during the time of Triassic til age of dinos equivalent to whales? I know back in the age of anomalocarids, the largest one seems to be a filter feeder that is niche-wise equivalent to modern whales.

People say Chihuahua, but when you DNA test them they come out as European dogs. My guess is that there has been SUCH a flood of European dog DNA introduced into the canine genome that most indigenous DNA has been drowned forever, sadly.

[@GrandviewKing]

Why are there so few large South American herbivores.. tapirs, llama and ilk, capybara .. probably an ungulate I’m missing but there isn’t much…

[@dr.polaris6423]

Because South America's once diverse megafauna perished at the end of the Pleistocene due to a mixture of climate change and hunting by humans. Of all continents, only Africa (as well as south eastern Eurasia) retained some of their original large mammals.

[@MrBonners]

Interesting. Never thought the idea of a South American 'dog/wolf/fox' animal'. .

[@BigJFindAWay]

I think that the Falkland wolf should be recreated by carefully over time selectively breeding maned wolves to have smaller ears, shorter legs, thicker coats, and more of a farm coloration.

They are a basal (primitive) member of the subtribe Canina, making there closest living relatives the African jackals of the genus (Lupulella), and not the Grey wolf of the genus (Canis) that was originally thought.
