The Future is Wild is a franchise focused on the possibility of how life would evolve in the future, focusing entirely on three distinct eras: 5 million years into the future, 100 and 200. Starting as a book co-written by Dougal Dixon (who also wrote After Man: A Zoology of the Future), it was later made into a documentary aired by Animal Planet, being a Canadian/European co-production. Eventually, it became popular enough to spawn a children's series; being made entirely in Canada, it lacked the accurate models of the documentary and added cartoonish animal CGI models.
After the End: The premise of the documentary is how life will evolve millions of years after humans are gone.
Animal Talk: In the children's series all animals (even absent brained invertebrates like jellyfish and sea spiders) are capable of sentience and speak a language of their own (which can be understood by all species apparently).
In the US release, humans simply left to settle/live in space. The probes documenting the various creatures were sent by them/their descendants.
In the UK release, humans are extinct.
But it's never said exactly how they went extinct. In nature, there are two ways an animal can become extinct: by being killed off, or by evolving enough that you're eventually considered a different species. The US version and the UK version are not mutually exclusive: humans could have gone off into space and diverged into multiple "alien" species over the millions of years, thus rendering Homo sapiens to be extinct while leaving other species of humans alive.
Bat out of Hell: The Deathgleaner; for some reason afterwards, bats disappear alongside other mammals, despite how adaptable they and other types of mammal like rodents are.
Big Creepy-Crawlies: Silver spiders, falconflies, slickribbons... hell, the future seems to be especially wild for invertebrates
Carnivore Confusion: In the children's series, every single animal is sentient; as a result, carnivores are portrayed as villains, ranging from genuine Affably Evil examples into at least one full fledged evil monster without a mind of its own.
Ethan: We could run around in the grass and play Marco Polo.
C.G.: You want to pretend to be the 13th century explorer who journeyed to China?
Crapsaccharine World: This is pretty much the Poggle's natural habitat. They are farmed by Silver Spiders, who provide them with loads of food, look after them, and protect them until they are fully grown, at which point they are brutally slaughtered and fed to the spider colony's queen.
Expy: Many creatures are expies of other animal species, both living and extinct, since they all fill similar ecological niches, and were subject to convergent evolution. There are also a lot of expys from After Man: A Zoology of the Future.
Snow Stalker: Bardelot
Shagrat: Woolly Gigantelope
Gannetwhale: Vortex and Porpin
Cryptile: Fin lizard
Scrofa: Zarander and Turmi
Spink: Termite Burrower
Great Blue Windrunner: Bootie Bird
Rattleback: The Grassland Rattleback is an expy of the Testadon and Spine-tailed Squirrel. The Desert Rattleback is an expy of the Rootsucker.
Feathered Fiend: The Carakiller. Also, while only trying to defend themselves, both the Gannetwhale and the Spitfire have very lethal defense mechanisms.
Giant Flyer: The Great Blue Windrunner. The sources don't seem to agree on its size; some offer a realistic approach at 3 meters (about the same size as the largest modern flying birds), but the official site states a wingspan of 15 meters, which would make flight impossible given how thin the atmosphere is at the altitudes it flies at and how narrow its wings are (though it can increase the wing area by raising its legs, which have wing feathers).
Humanity's Wake: The British version of the documentary was after humanity went extinct, the American version changed it so that the human race simply left the system.
Kaiju: The Toraton. Weighing 120 tonnes and 15 times the size of an elephant, the Toraton is the biggest animal ever to live (dwarfing even the largest known dinosaur, the 90-ton Argentinosaurus).
Killer Rabbit: The Snowstalker, the Spitfire Bird, and the Gryken
The Spitfire Bird, at least. While the Snowstalker and Gryken aren't much bigger than a wolverine, they look just as scary as they act.
Irony: "These strange creatures are called Babookari." Yeah, compared to tree-swinging squid, jumping snails, flying fish, acid-shooting hummingbirds and dinosaur turtles, a blue-assed baboon would look really strange.
Light Is Not Good: The Sharkopaths, whose yellow bioluminescence fits them well. Also, one of the main problems for life in the high plateau is ultraviolet radiation, and thus both the Windrunner and the Silver Spider reflect it, looking as if glowing in blue and silver light respectively.
The Deathgleaner, a gigantic carnivorous diurnal bat, also fits this trope.
Mix-and-Match Critter: Justified that convergent evolution has forced new creatures into vacated niches, and so adapted into a form that resembles a now-extinct familiar animal (whether prehistoric or from the age of man).
Ragnarok-Proofing: Completely and utterly averted. The only times it's brought up are during the Paris time lapse scene and occasional mentions of how geological processes would have long destroyed any sign of human civilization.
Super-Persistent Predator: Refreshingly averted. The Snowstalker reastically flees after the Gannetwhales bombard it with their vomit, the Deathgleaners give up on attacking the baby Rattleback after its mother charges them, and the Falconfly flees after the Spitfire Bird starts squirting it with reactive chemicals. Granted, the Snowstalker does wound a Shagrat and track it down until it dies from blood loss, but this is a Real Life tactic that many predators use.
Team Pet: Squibby the Squibbon from the children's series.
Too Dumb to Live: If you're a juvenile Toraton, then walking straight into a nest of amphibious squid, with a highly venomous bite, may not be such a good idea.
The lost baby Scrofa, that, separated from its parents, runs out into the salt desert until it dies of heatstroke. When it was alredy on a safe place among the rocks, at that!
Too Important to Walk: Every terabyte caste except the porters, which haul the other castes' members around.
Totally Radical: In the children's series, the Antarctic Forest is described as 'trippy'. Uh, that's not really what trippy means...
Vomit Indiscretion Shot: Literally. The Gannetwhales regurgitate and spit their last meal at possible predators while they are incubating their eggs at the shore.
To explain, the toraton is introduced as an elephant-sized herbivore descended from tortoises. It is then killed by a swampus. We then find out that it was only a baby. Adult toraton are the heaviest land animals ever, and have no predators.
