You'd never guess which species orcas evolved from
They are among the most formidable animals in the ocean - pack-hunting creatures that feed on everything from salmon to blue whales. Orcas, like all whales, are mammals - they breathe air and feed their young with milk, but their ancestors are not who you’d expect. #TheNatureOfThings #ListeningtoOrcas

The very first “whales” were land animals that walked on four legs - small deer-like creatures, about the size of a house cat, that ate plants and waded around in prehistoric lagoons over 50 million years ago.
But in the span of just 10 million years, those land-living vegetarians lost their hind legs, grew flippers and fins, to become the streamlined giants of the seas.
The closest-living relatives of orcas are hippos, but a modern example of what their ancestor may have been like is the chevrotain, a small deer species that dives into water when threatened, hiding from predators below the surface.
John Ford, a zoologist and renowned expert in orca acoustics, describes how orcas adapted to the ocean habitat. Watch the video above for the full story.

Thought this was going to be about how ancestral orcas (like O. citoniensis) were much smaller and less formidable than modern orcas, eating only small fish and squid.
Life starts from the ocean, evolves to adapt to land, land creature evolves to adapt back to ocean
Recent studies are starting to show that certain cultures of Orca might actually different species of Orca.
Totally makes sense that the land animal closes to a whale is a hippopotamus.
Orcas YOU SCARE me ...and also fascinate me 😅😅😅
Uh Just hjjjjmkkjjjjkk job jkjk ok Ik kjkkhgkkjnulhgjgl Gghg I’ll k Lily My uhh I

They are sonic creatures they can see if you breathing, heart beating, if your pregnant
Orca Well probably appeared in the miocene Before pliocene Megalodon went until the last ice age, there Orcinus Citonesis Orcinus meyeri and Orcinus paleorca
2:31 certainly salmon
I don't care what they say behaviour wise it's closest relative has to be the wolf
A cow is much near to an orca than a wolf since they are artiodactylous
How closely are each of the other whales like sperm whale, blue whale etc related to the orca? Isn’t an orca more similar to most dolphins than are to the other whales? When was the orca’s and sperm whales’ last common ancestors?
Totally since orcas ARE dolphins
Why didn’t whales evolve like killer whales?
What the hell is that thing!!!?
hippos and boars. without even watching the video
Without even editing the comment, either, lol. All hail the supreme intelligence, people.
Haha~ it aint get any crazier than this in modern times. Great Whites aren't related with Megalodons but Orcas and Hippos do? Hahahaha~
Megoladon is related to GW as they are both sharks, but not the same species of Shark, Megoladon is an Otadus while GW is Charcarodon.
Next they will tell us we evolved from primates 🤪
Would you consider Neanderthals as primates?
@@caniform-craze2080 they are a form of ape what are togheter with monkeys primates
carnivorous cows it was a wolf like creature mesonychid guys an idiot
I mean... yeah? and Birds are Dinosaurs. Just because your shrimp brain is too simple to understand it doesn't make it not true
White ppl are the only Neanderthals
Orcas aren’t whales why he call em that they’re dolphins
Probably because all cetaceans (whales, dolphins, and porpoises) get classifyied into the groups of toothed or baleen whales
Killer Dolphins is what I call them
one day a fish decide to left water and be the first land dweller. Next wolf decide to back to water and be water panda. Who knows what scary thing orcas gonna become if they decide to march on land
You have to Google what a mudskipper is
This all sounds so far fetched
they evolved from mesonychid a wolf like creature cows were not carnivorous
Mesonychid was still an ungulate like cows and hippos. and Orcas are still more closely related to it than to wolves.
They doesn’t have any relation with canids doesn’t matter if you see their ancestors with a dog/wolf form. They are artiodactylous , is rare now a days but in the past some land artiodactylous where carnivours the biggest carnivour land mammal (Andrewsarchus) was one of them
Baloney..
See anti captivity people, the dorsal fin is floppy because there is no bones in dorsal fin, just cartilage.
tbf the reason the dorsal fin is floppy is because of warm air. Orcas that perform tends to expose their backs to warm air much more often than wild orcas. So it is indeed correct that the floppy dorsal fin is not in any way connected with emotion captivity is still bad.
...this is so sad how you geniunely think its because of that
It's floppy because its meant to give them balance when swimming in the open ocean, if it's flopped to its side because the pool they secluded it in was too small than that's not good. what was your point? Do you just want Orcas to suffer in tiny spaces?
Both wild and captive orcas exhibit flopped fins, but captive ones do so dramatically more often.
I think they evolve from a bat like ancestor because of their echo location abilities
Sperm whale: sobbing
The wolf, it makes more sense
@@Ron_swanson_true_libertarian how does it makes sense
@@___Anakin.Skywalker they live in and hunt in social groups like wolves...
@@littlesongbird1 bats are social creatures as well. They live in communities plus their echo location abilities it's makes more sense to me
someone lie
Unremarkable
Excuse me Sir/Madam Are you saved? If you died tonight are you going to heaven? Jesus loves you. Jesus is King.
Nobody is going to heaven. Stop trying to turn people on yt videos that have nothing to do with religion. It's incredibly annoying.
Anna133199 The Bible is a historical fact Did you know about Earth when you were in your mum’s womb? For God so loved the world that he gave his only son that whoever believes in him shall not perish but have eternal life You are a person born to be loved God bless you
Anna133199 Up to you God gave us free will You choose where to spend your soul in heaven and hell There surely is a heaven and hell Jesus loves everyone even Jesus loves your enemies
