What if Humans & Carnivorans Disappeared? (Ep. 1 North America)

A speculative evolution (spec evo) video in which we explore what would happen to the animals of North America if humans and carnivorans were to disappear. What would happen to the herbivores now that their predators have gone? Which animal would become the top predator?

This was a really intresting and entertaining video I enjoyed it very much, I hope that you make a part 2. Thanks for your work it's really good 👍🏻

[@Eco-Nerd]

@@adamalbury111 Thank you! That's a really nice compliment 😊 I'll get around to it eventually when my channel is a bit more established and hopefully this video performs a little better

[@Coelacanth_yes]

The water opossum is another example of an animal filling the niche of an otter

[@Eco-Nerd]

@@Coelacanth_yes Yep that could happen too!

[@the13thwizard]

I would like to see more development in North America, but I would be curious about South America, Australia, New Zealand, and Madagascar.

[@Eco-Nerd]

I'd be interested to see what's going on in South America in this world. Mostly because that's where the Seriema lives, for those who are unaware, they're basically the South American version of the African Secretary bird, and out of all living birds they are the closest living relatives of the extinct Terror Birds and the most likely to evolve into that niche. We could see Seriema-descendants evolving into Terror Bird-esque forms within the first few million years easily, for most other species it would take considerably longer to evolve into that niche.

[@Eco-Nerd]

@@jessejarmon2100 Yeah they'd definitely be one of the top candidates for being the apex predator in the future!!

[@jessejarmon2100]

@@Eco-Nerd Also, fun fact: Seriemas have sickle claws on their feet exactly like those that the extinct dromaeosaurs like Velociraptor had, and they use them in much the same way as dromaeosaurs are thought to have. By pinning down small animals like lizards while ripping them apart with their sharp beak.

[@Eco-Nerd]

@@jessejarmon2100 That's pretty cool!

[@IkeReviews]

What about escaped zoo animals like life after people covered like elephants rhinos gazelles escaping zoos

[@Eco-Nerd]

@@IkeReviews Yeah some animals could definitely escape or be released! I can only focus on so many animals in one video but that's a cool idea!

[@aspiewithattitude3213]

Most birds of prey could evolve into a flightless terror bird V2.0

[@Eco-Nerd]

@@aspiewithattitude3213 yeah that's definitely another possibility! Could happen for other birds too even turkeys eat lizards, frogs and other small animals! Birds of prey would probably be a better candidate though 🤣

[@aspiewithattitude3213]

@@Eco-Nerd We can never forget that birds are suppose to be descendants of dinosaurs. Even reptiles could become dinosaurs V2.0 starting up a "Nova-Jurassic Proxima" era. Overtime continents will continue to drift and in that time the dinosaurs would get a second chance.

[@Nosoyplex1929]

Also you have seen me today but I don’t know if you have made a Latin American video as latin America has a great fauna and with out jaguars and cougars or even bush dogs it will be pretty interesting Some ideas for the video: because the fauna of the Amazon and Central America are mostly liked the most semiacuatic ecosystem in earth it will most likely caimans and harpy eagles became the apex’s predators while in the South Americans savannahs rheas and deers from the zone will most likely boom in the population and in the South American Patagonia and Andes with out predators like cougars the ecosystem will be out of predators as one of the last predators Andean condors which are most of the times eat already dead animals will be one of the last candidates from the Andean to be a predators Sorry for my ingles *is inglish in spanish* Also awesome video!,

[@Eco-Nerd]

@@Nosoyplex1929 yeah South America would be a cool one! It's on my list 😎

[@Nosoyplex1929]

@@Eco-Nerd ty!

[@Coelacanth_yes]

It's also Important to note that due to the connection of north and south america some herbivores and carnivores will move between them

[@Littlekoji-df1cf]

I would go trought each Continent first. Then take a look at them with more time passed

[@Eco-Nerd]

@@Littlekoji-df1cf yeah I think that's what I'll go for! Thanks for the suggestion 👍

[@Littlekoji-df1cf]

​@@Eco-Nerdno problem

[@dariusbrock2351]

I wonder how well would zoo animals would fare if they were able to escape?

[@Eco-Nerd]

@@dariusbrock2351 Yeah I guess it depends on the species and the part of the continent they were in, if people released them before they died and a million other factors!

I'm 3 minutes in, wracking my brain for non Canovira carnivores in North America. And I'm going to go for the ubiquitous Common Opposum as the most likely candidate for taking over that mantel... and/or feral pigs/boar. Shrews and moles are another potentially interesting avenue. We'll see in 9 minutes I guess 😅😅 Edit: How could I forget the Archosaurs?! Red Legged Sereima are another interesting possibility there. The return of the terror birds. And you forgot the escaped elephant herds ;)

[@Eco-Nerd]

You got them fairly spot on! I did think about a terror bird equivalent but I thought there were too many animals ahead of it in the pecking order. Yep, there'd definitely be some zoo escapees 😉

[@Eco-Nerd]

@@rewild6134 Just looked up Sereimas there. I thought I'd never heard of them but I'd just forgotten there name, I remember seeing that they're the closest living relatives to terror birds and also it's the bird that bounces the golf ball 🤣 From what I can see, the two species are only found in South America though

[@rewild6134]

@Eco-Nerd Haha, thanks 😅, I like the extinct Carnivora twist to the Life After People theme 👍 You don't happen to follow Trophic Rewilding and De-extinction on Facebook do you? I think you'd fit right in there 👌 I honestly thought you were one of the other admins (who's also Irish) with a secret KZbin account 😄

[@rewild6134]

@Eco-Nerd They are, but without people, there are fewer barriers to wildlife moving between the Americas, likely particularly so if there are no Carnivorans.

[@Eco-Nerd]

@@rewild6134 thanks! I was trying to do something different with it but the video hasn't done too well. The rewilding videos are growing the channel some bit though.
